["FLYSCH , a remarkable formation, composed mainly of sandstones, soft marls and sandy shales found extending from S. W. Switzerland eastward along the northern Alpine Vienna basin, whence it may be followed round the northern flanks of the Carpathians into the Balkan peninsula. It is represented in the Pyrenees, the Apennines, the Caucasus and extends into Asia; similar flysch-like deposits are related to the Himalayas as the European formations are to the Alps. The Flysch is not of the same age in every place; thus in the western parts of Switzerland the oldest portions probably belong to the Eocene period, but the principal development is of Oligocene age; as it is traced eastward we find in the east Alps that it descends into the upper Cretaceous, and in the Vienna region and the Carpathians it contains intercalations which clearly indicate a lower Cretaceous horizon for the lower parts. It appears indeed that his type of formation was in progress of deposition at one point or another in the regions enumerated above from Jurassic to late Tertiary times. The absence of fossils from enormous thicknesses of Flysch makes the correlation with other formations difficult ; often the only indications of organisms are the abundant markings supposed to represent Algae (Chondrites, &c.), which have given rise to the term " Hieroglyphic-sandstone." The most noteworthy exceptions are perhaps the Oligocene fish-bed of Glarus, the Eocene nummulitic beds in Calabria, and the Aptychus beds of Waidhofen. Local phases of the Flysch have received special names; it is the " Vienna " or " Carpathian " sandstone of those regions; the " macigno " (a soft sandstone with calcareous cement) of the Maritime Alps and Apennines; the " scagliose " (scaly clays) and " alberese " (limestones) of the same places are portions of this formation. The grès de Menton, the grès d'Annot of the Basses Alpes, and the grès d'Embrun of Chaillot appear in Switzerland as the gris de Taveyannaz. At several places the upper layers of the Flysch are iron-stained, as in the region of Leman and at the foot of the Dent du Midi; it is then styled the " Red-Flysch." Lenticular intercalations of gabbro, diabase, &c., occur in the Flysch in Calabria, on the Pyrenees. Large exotic blocks of granite, gneiss and other crystalline rocks in coarse conglomerates are found near Vienna, near Sonthofen in Bavaria,near Lake Thun Wild Flysch and at other points, which have been variously regarded as indications of glaciation or of coastal conditions."
Are the absence of fossils and the presence of iron impactmarkers ?
Jacques Debelmas mentions from page 36 to page 38 of "Discovery of Geology of Southern Alps": "... a rhythmic alternation of sandstone benches, some coarse, the other very fine black silt (called pelitic ...). This sandwich is probably [not] ... from climate origin... such alternatives are known as flysch tertiary sandstone ... these are often folded dramatically. ... The schistosity becomes the rule ... "
Is there sorting of coarse-grained and silt and ejection linked to an impact? Does the heat of the ball of fire over 3000 ° operates "mille-feuilles" (thousand sheets pastry in french) cooking ? The Science special file of April/June 2006 "The raging elements" says page 112 ( "Avalanches of mud and snow" by Christophe ANCEY and Eric BARDOU): "... for fast fluid inertia interstitial increases, and the liquid penetrates the grain and contacts. The mixture behaves like a liquid. This is for debris flows and avalanches aerosol. When we add colloidal particles, like clay, the behavior of the suspension becomes more complex, and varies with time. In terms of very short solicitation, the material behaves like a viscous liquid, while on long time, it looks like a granular material. In fact, after few seconds, it breaks the contacts between the coarse particles, causing the "liquefaction" of the material. When we seek the mixture on longer time (several minutes) the particles heavier than the interstitial fluid have time to settle and the fluid between two neighboring particles is expelled [as in LOWE sequences ?]. The material behaves so again granular ... "

KEY POINTS :
Plate tectonics (continental drift) provides the global and local explanation for physical geography: it defines the system of the landscape. It became scientifical thanks to the geophysicists.
The best works (in French) are those of Mattauer ("Mounts and wonders" and "What do the stones say", best initiation), Debelmas and Mascle ("Great geological structures", general panorama), Jolivet and Nataf ("Geodynamic and deformation of the continents", presentation of the mechanisms), Lemoine, de Graciansky and Tricart ("From the ocean to the mountain chain. Plate tectonics in the Alps", a wonder of clearness), under the direction of Avouac and De Wever ("Himalayas-Tibet. The shock of the continents", a wonder of clearness which explains pages 48 and 60 the origin of the molassic basins of Po and Swiss plate and page 62 the collapses type Bassin and Range), Dercourt ("Geology and geodynamics of France"), the websites Tethys http://www-sst.unil.ch/research/plate_tecto/prototet.htm http://www-sst.unil.ch/research/seismic/W_Alps.htm, http://www.geol-alp.com , sous la direction de Avouac et De Wever Elmi and Babin ("History of the earth", with a good history of the continental drift between Rodinia and Pangea) and especially Girault, Bouysse and Rançon ("Volcanos seen from space", world panorama exceptionally clear by its charts and its comments).

|Neville PRICE, London University College, with "Major impacts and plate tectonics", when he was 71 years old, will be the 2000 year WEGENER. Andrew Y.GLIKSON is following not very far from him.http://www.mantleplumes.org/WebDocuments/Glikson1999.pdf http://www.futura-sciences.com/news-asteroides-massifs-ont-transforme-surface-terre_6888.php|
"Neville Price evaluates the mechanisms that give rise to plate movements. Generally, such plates move slowly at about the rate-of-growth of human nails and their tracks are usually smooth, gentle curves . "Major Impacts and Plate Tectonics" presents evidence to show that impacts can cause significant and dramatic changes in track, which cannot be explained by current theories of plate tectonics. The book also demonstrates that such major impact events often coincide with the development of continental flood basalts and oceanic plateau basalts and frequently coincide with major stratigraphic stage boundaries and toxicity, which in turn can be associated with periods of extinction. It concludes that geological history comprises periods of relatively orderly, evolutionary change in Earth and life-forms punctuated by catastrophic changes induced by major impacts that reset the evolutionary clock."
For Gregory Retallack it is possible that a giant meteor impact triggered Siberian traps http://126.96.36.199/search?q=cache:ghi35WSVcEQJ:membres.lycos.fr/jcboulay/astro/sommaire/astronomie/univers/galaxie/etoile/systeme_solaire/terre1/extinction/page_extinction.htm+trapps+impact&hl=en
"Previous tests by Poreda on this same layer found shocked quartz and fullerenes, cage-like molecules, containing atoms of extraterrestrial gases, which again hinted at a meteorite or comet strike. These results, however, were disputed by some researchers. Coming at the problem from another angle, Basu and Poreda separated out the magnetic particles from the samples from Graphite Peak and from a source of P/T strata in Meishan, China, and Japan. To their surprise they found that the grains that sorted out contained an iron alloy that does not occur on Earth. Some 40 pieces were tiny fragments of meteorite 4.56 billion years old, while other grains displayed metallic characteristics that were more indicative of being formed by extreme heat, such as that in a severe meteorite impact. The very fact that these grains had not deteriorated from weathering means they must have been buried quickly under sedimentary deposits, again, indicative of a major impact... Critics of the P/T impact theory may point to the lack of iridium, the element that is so rare on Earth but common in asteroids and which alerted Alvarez to the possibility of a meteorite as the death knell for the dinosaurs. The Rochester team's work shows strong evidence that not all collisions with extraterrestrial bodies will leave an iridium footprint. Basu suggests that a collision with a comet, which may have a meteoric core, would be low in iridium."
Panjal and Emeishan are related to rifting and extinction. Traps are linked to less known extinctions : Baltic Shield and Pripryat Dniepr Donets (Dévonian) et CAMP (Trias-Jurassic) avec the begining of North America rifting and a huge trap over America, Africa and Western Europe.
For dinosaurs extinction : "... the occurence of a thick shocked quartz layer below the lowermost lavas flow strongly imply that the Deccan volcanism may have been triggered by the Shiva impact..."
For Jones the giant meteor impact crater is under the trap basalt flood : "Adrian Jones models the effects of impact on the Earth's geological crust. He has a hunch that meteorite crater hunters are looking for the wrong thing. After an impact, the crust rebounds to form a large shallow crater. If the meteorite is truly massive though, an extra process occurs. The combined heat of the impact and rebound is enough to melt the crust. Lava floods through and the crater disappears beneath new crust. If he's right, the Permian meteorite crater can't be found because it doesn't exist." Michael Rampino is often quoted : ""In fact," he says, "I think there's a case to be made that large impacts may be the triggers for large-scale tectonic movements and massive volcanic eruptions. If this is true, then to a large degree, huge impacts control the geology and biology of Earth."... "There are too many coincidences for there not to be a connection between impacts, basalt volcanism and mass extinction," Rampino asserts."
For Becker in Pour la Science mai 2002 p65, at the Permian end a meteor would probably strike Panthalassa with few impact products.
"Massive Meteorites in Geological History" (by David ALT, James W. SEARS, Donald W. HYNDMAN). "The impact of asteroids or comets striking the earth may have cracked the planet's crust, causing cataclysmic lava flows, environmental upheaval, mass extinctions, and plate boundaries... All of the earth's flood basalt provinces appeared suddenly within plates, without any recognizable setting in previous events. No evidence suggests that the earth generates them through its own internal processes; they just happen, exactly as you would expect of asteroid or comet impacts. Most flood basalt provinces are the starting points of oceanic ridges; all oceanic ridges started in flood basalt plateaus. The evidence shows that impacts establish new plate boundaries, thus setting the pattern of plate motion. The earth does not set its own agenda of plate motions; instead, it passively awaits its destiny in random collisions with wandering asteroids or comets."
For Andrew GLIKSON, Australian National University, 1999 "... Isotopic ages of crater clusters and flood
basalts increasingly allow tests of possible genetic relationships
between these clusters, episodic continental flood volcanism, rifting
and continental breakup... "http://abob.libs.uga.edu/bobk/ccc/ce051499.html

"A great rift known the Narmada Son, extends east-west across India. Seismic data indicate that it crosses the Moho into the mantle. When the Narmada Son rift passed over the Deccan Traps plume head, basaltic lavas were able to quickly flood through it along a great distance." " The Gulf of Cambay lies on the triple junction as three major tectonic lineaments originate from here: Cambay rift and Panvel flexure running in north-south direction and Narmada-Son rift in EW direction. The Narmada-Son lineament is seismically very active and marks the boundary between shield and Indo-Gangetic plain." Was Indian Ocean rifting due to Shiva impact ?

Are oceanic plateaus linked with arcs : "Very recent developments suggest that oceanic plateaux in the Precambrian are the focal point of continental growth. Such plateaux even in the Cretaceous are as big as France, and their thick basaltic sequences, coupled with the presence of high-temperature komatiites, suggests they have formed by decompression melting of mantle plumes. Whereas greenstone belts are now widely regarded as Precambrian oceanic plateaux, it is apparent that up to 50% of them have arc-like compositional characteristics, and are extensively invaded by contemporaneous tonalites. This project is designed to examine the relationship between mantle plumes and arcs..." For Neville Price in "Major impacts and plate tectonics" p263-267 Mariannes arc is linked with an impact.

For Gregory Retallack... it's possible that an impact induced Siberian traps.
"Previous tests by Poreda on this same layer found shocked quartz and fullerenes, cage-like molecules, containing atoms of extraterrestrial gases, which again hinted at a meteorite or comet strike. These results, however, were disputed by some researchers. Coming at the problem from another angle, Basu and Poreda separated out the magnetic particles from the samples from Graphite Peak and from a source of P/T strata in Meishan, China, and Japan. To their surprise they found that the grains that sorted out contained an iron alloy that does not occur on Earth. Some 40 pieces were tiny fragments of meteorite 4.56 billion years old, while other grains displayed metallic characteristics that were more indicative of being formed by extreme heat, such as that in a severe meteorite impact. The very fact that these grains had not deteriorated from weathering means they must have been buried quickly under sedimentary deposits, again, indicative of a major impact... Critics of the P/T impact theory may point to the lack of iridium, the element that is so rare on Earth but common in asteroids and which alerted Alvarez to the possibility of a meteorite as the death knell for the dinosaurs. The Rochester team's work shows strong evidence that not all collisions with extraterrestrial bodies will leave an iridium footprint. Basu suggests that a collision with a comet, which may have a meteoric core, would be low in iridium." http://www.eurekalert.org/pub_releases/2003-11/uor-nes112003.php http://appl003.lsu.edu/unv002.nsf/9faf000d8eb58d4986256abe00720a51/fe4ed1a5901f7ba086256d42006edcaf?OpenDocument
What about Panjal and Emeishan related with rifting and extinction ? Baltic Shield and Pripryat Dniepr Donets (Dévonian) and CAMP (Trias-Jurassic) with the beginning of North America rifting ?
For KT extinction : "... the occurence of a thick shocked quartz layer below the lowermost lavas flow strongly imply that the Deccan volcanism may have been triggered by the Shiva impact..."
James Lawrence POWELL, “Night Comes to the Cretaceous: Comets, Craters, Controversy, and the Last Days of the Dinosaurs”, about Deccan traps: “... a group of Indian geologists, led by N. Bhandari...sampled in the Anjar region of Gujurat State, where seven basalt flows are recognized, each separated from the next by intertrappean sedimentary layers several meters thick. The third intertrappean bed from the bottom, ITIII, contains bones and eggshells of dinosaurs.The Indian geologists used the argon-argon method to date the lava beds designated FIII and FIV, which lie above and below ITIII, at 65.5 ± 0.7 and 65.4 ± 0.7 million years, identical to the 65.0-million-year date for the K-T boundary. (This evidence also shows that dinosaurs were still alive up to the very end of the Cretaceous.)” Not only were dinosaurs not found in the first two intertrappean layers, which show that dinosaur fossilization is exceedingly rare in this locality, but they were found in the 3rd layer (along with dinosaur eggshells!), thus simultaneously proving that not only did the dinosaurs survived the first several episodes of volcanism, but they died right at the K-T boundary, and in such large numbers that either the decomposers and the scavengers (which were probably also killed in large numbers) could not finish their work before the sediments covered up the carcasses, or else the iridium rich dust that must have been thrown into the atmosphere in large quantities covered up the carcasses before all of them can decompose completely. BTW, the sediment found immediately above the dinosaurs at this locality is iridium rich while the volcanic basalt is atypically iridium poor, showing that the iridium comes from the meteorite and not the volcanic activity."
For Jones the impact crater is under the trap : "Adrian Jones models the effects of impact on the Earth's geological crust. He has a hunch that meteorite crater hunters are looking for the wrong thing. After an impact, the crust rebounds to form a large shallow crater. If the meteorite is truly massive though, an extra process occurs. The combined heat of the impact and rebound is enough to melt the crust. Lava floods through and the crater disappears beneath new crust. If he's right, the Permian meteorite crater can't be found because it doesn't exist." For Michael Rampino : ""In fact, I think there's a case to be made that large impacts may be the triggers for large-scale tectonic movements and massive volcanic eruptions. If this is true, then to a large degree, huge impacts control the geology and biology of Earth."... "There are too many coincidences for there not to be a connection between impacts, basalt volcanism and mass extinction," Rampino asserts."
For Becker in Pour le Science mai 2002 p65 : "... At the end of Permian... un impact would probably occur on Panthalassa. With few impact products... "
"Andy Saunders is Professor of Geochemistry and has extensive research experience in the study of mantle plumes. He has carried out investigation into the origin of large igneous provinces for several years and is currently studying the links between flood basalts, bolide impacts and mass extinctions." http://www.le.ac.uk/gl/ads/adsnew.html
"New theory explains flood basalts of Columbia Plateau and the hotspot track of Snake River Plain as result of giant meteor impact about 17 million years ago." (est-ce le cas de Long Valley, du Toba, du Taupo, comme de Yellowstone ?) For Neville Price in "Major impacts and plate tectonics" p199-200, CRBG Columbia River Basalt Group is related with jetting (Rattlesnake and Horse Heaven Hills).
For Ontong Java an impact is possible : "... Rogers (1982) suggested that the Pacific plateaus represent massive outpourings of basalt formed by the cataclysmic excavation of asthenosphere by large but rare meteorite impacts. We find this hypothesis attractive in that it can explain the absence of a post-plateau seamount chain and any obvious present-day hotspot that can be linked with the OJP... Another potential advantage of the impact hypothesis is that it may help explain the enigmatic 300-km-thick, seismically slow mantle “root” beneath the OJP (Ingle & Coffin, 2004)..." "... Thus as recently suggested by Cofin and Ingle (AGU, EUG Nice Meeting April 2003), the Ontong Java Oceanic Plateau does not seem to be explainable by the plume hypothesis, but rather they advocate an impact origin... The fundamental relationship between impact-generated melt volume (both from kinetic energy and gravitational energy via decompression) and thermal structure is reminiscent of the komatiite conundrum."
For Neville Price in "Major impacts and plate tectonics" p206-210 Ontong Java is linked with an impact and has same age near structures Manihiki, Nauru basin, Pigafetta and East Mariannes basins.
Are Mexican Gulf and Carribean trap related with impacts ? "Satellite-derived bathymetry reveals a circular depression, some 180km in diameter, on the floor of the Venezuelan Basin, just SE of the Beata Ridge (intersection W70°-N15° falls on its eastern rim at 3 o’clock). I christened this the Beata Crater. I am tempted to relate it to a regional, abrupt and violent Middle Eocene event in which giant olistostromes became emplaced around the Caribbean and to the Eocene strewn field of the SE USA. This was also the beginning of easterly drift of the Caribbean Plate relative to both N and S America. However, the Beata Crater is unconfirmed by geophysical/geological investigation and its age is unknown. It could be an oceanic relative of Chicxulub. A further circular anomaly, which I tentatively name the Tierra del Fuego Crater, occurs at 64°30’W, 56°30’S, close to the tip of S America." For Neville Price in "Major impacts and plate tectonics" p240-255 Carribean and Scotia plates are linked with impacts.
Was Corsica-Sardinia movement linked with an impact ?
For Louis Lliboutry « Géophysique et géologie » Masson 1998 pVI « plate tectonics theory has limits and do not explain that basins occur suddenly on the borders of continents..."
Louis Lliboutry asks good questions p334-342 : Appenins came from nowhere from the west where there is a hole today. Is the Tyrrhenian sea linked with an impact ? Calabria is a terrane. Lliboutry can't understand how it came. The dykes are radiating in the Tyrrhenian sea (E-W, N-S et NE-SW). The Wadati-Benioff plan is fluted. It's the same for Valencia basin, Alboran sea, with an ophiolites belt, RIf and Betic cordillera jetting. For Lliboutry there is no subduction in Ionian basin.
The crust swelled and then collapsed creating Thyrrhenian basin. It's an impact story !
Is it the same for Aegean Sea where a moutain chain disappeared ?
Was hercynian Brittany-Galicia arc destroyed by an impact ?
Antalya-Adalia gulf looks like Bas-Dauphiné with Jura looking like Cilicia and Cyprus. Is Oman related too with an impact ?
For Jolivet in « La déformation des continents » p343 : « In fact thyrrenian extension is related with Appenins collapsing as soon as forming… » Alpin Corsica ["Géologie et géodynamique de la France" by Dercourt p99] looks like Aegean Sea. « … like in the west Pacific one does not understand the engine of this back-arc extension... There is the same process in the Alps in Dora Maira..." Impacts ?

What about (on Geology map of France by BRGM 1/1 000 000) the huge block south of Limagne between Ambert and Brioude basins ? Are Velay and Forez basins related with impacts ?
Do 3 impacts explain Bassin Parisien ?
- huge curl in south-west Normandy drawing jurassique and crétacé arcs as far as Basse-Seine and Beauce.
- geological 2000 m hole Orléans-Vierzon inducing the curl Val de Loire, Sologne, Beauce, Indre, Berry jurassic.
- geological 3000 m hole Ourcq-Grand Morin drawing East Bassin Parisien (is there an impact going from Champagne to Southampton, with 3 curls Champagne Ile de France Picardie coast and the tail on Southampton).
The micro-maps "cycle alpin" and "cycle varisque", on Geology map of France by BRGM 1/1 000 000de, ask the following questions :
- are the "reliques de croûte subductée" related with impacts (Nantes, Rochechouart, Limagne, Grands Causses, Forez-Lyonnais) and what about Velay ? The huge circle in the Grands Causses V pointing to the north-east gives on Michelin map an extraordinary ovale, centered on Pareloup lake and going from de Pont de Salat to Alrance and Bouloc by Pont de Prunhac with radiating rivers and another wave from Forêt des Palanges to Puech del Pal and Puech de L'Oule.
- are the big faults related with impacts on Atlantic Ocean and on Po basin?
- does Parentis hole draw Arcachon basin and river la Leyre, Landes sands and forest, the jurassic busting Massif Central ?

"Géologie de la France" tome 1 by Debelmas p406 : there are two V shapes in the South Alps [ http://skaly.lezec.cz/clanek.php?key=914 shows an ovale near Annot]. The Bornes arc with two symetrical klippes has a hole on the east (Megève basin and Contamines). There are diapirs on Ventoux Valréas Sisteron Vallée des Merveilles. "De l'océan à la chaîne de montagne. Tectonique des plaques dans les Alpes." by Lemoine, Graciansky, Tricart, p165, asks questions about Dévoluy.
What about 2 impacts on Chamonix and Megève : with an odd symetry. Chamonix arc (busted south-east by Megève impact ?), Val Ferret/Dranse de Ferret-Val Veny/Cormet de Roselend, Brévent-Aiguilles Rouges, Col d'Anterne-Mt Buet, Désert de Platée-Cirque du Fer à Cheval, klippes and jetting on Chablais... North-west curl and south-east curls for Megève, vallée des Contamines, Nant Rouge-Dorinet-Doron, Val de Sallanches- Val d'Ugine-Faverges, Bornes arcs, Aravis extraordinary fluting (like Tyrrhenian sea and east of Valréas... ), klippes.
Pelvoux is also symetric. Mont Blanc and Pelvoux have central "coffee grain" shape. Pelvoux (Val Jouffrey et Val Senestre, Champoléon) and Argentera have "coffee grain" and spread-out shapes. Related with impacts ? Are Doigt de Dieu in la Meige and Dent du Géant, Dibona, Dru and Dent du Caïman, Capucin, Aiguilles de Chamonix and Grandes Jorasses shapes related with impact. If yes, is Fitzroy linked with an impact ?
Is the heart of Vanoise, with les Trois Vallées, the tail of a huge impact ?
Is Arvan valley, south of St Jean de Maurienne, with horseshoe shape, related with an impact ? look at http://www.geol-alp.com/h_maurienne/_lieux_maurienne_Sud/Mt_Falcon.html Valloire valley western side ends with a huge wall . The trail "GR de pays Arvan-Villards" makes a curl around Mt Falcon. Aiguilles d’Arves and Roche Courbe are symetric with three symetric valleys southwards. Northwards there are Charbonnet and Mt Charvin uplifts, Arvan canyon, , forêt du Rieubel listric valley, Fontcouverte byke circus. Eastwards and westwards Valloire and col du Glandon valleys, Setaz and Etendard. Have a look on http://www.geol-alp.com/h_maurienne/_lieux_maurienne_Sud/CombeGenin.html http://morphoglaciaire.free.fr/site_source/Photos_complementaires/aiguilles_cargneule.html Are the rauhwacke "fairy chimneys" ("cheminées de fées") markers like shattercones ?

Mt Charvin looks like "Upheaval Dome" in Utah. Is Valloire valley with Galibier a kind of Taylor Canyon ? Is Rubielos de la Cerida spanish impact a Mt Charvin Mt Falcon shape http://www.impaktstrukturen.de/spain/rubie/Topography.htm [this website in german is wonderful for impact geological markers]
The "demoiselle coiffée" in Albiez le jeune has a curved column and a top rock which looks like a shattercone...
[Is Laus diapir, with "demoiselles coiffées" of Théus, related with an impact as the "demoiselles coiffées" of Bolzano ? Laus diapir is in the center of Gap curl, on SE-NO axis, with a tail on Serre-Ponçon and Remollon klippe on the side. Or is it related with the end of a schockwave coming from Trentino ? There are "demoiselles coiffées" east of Bédoin in the heart of Ventoux impact. UPHEAVAL DOME AND ARVAN SHOW THAT "RAUHWACKE FLAMES SHAPES" ARE ON THE CENTRAL UPLIFT AND "DEMOISELLES COIFFEES SHAPES" ON THE IMPACT CRATER RIM (Albiez le Jeune for Mt Charvin !)

Italy has "piramidi di terra" erdpyramiden : Segonzano north-east from Trento ; Renon Ritten and Plata Perca north-east from Bolzano ; Terento north-east de Bolzano before Brunico ; San Genesio au nord from Bolzano ; Cislano Zone noth from Brescia and north-east from lago d'Iseo ; Sondalo north far from Brescia ; Postalesio north from Bergame et au nord-est de Lecco ; Rezzago west from Canzo and Lecco ; St Nicolas en Val d'Aoste ; Protomagno di Sopra in Etruria. They are concentrated near Bolzano curl or near the lakes. For Bolzano curl: Drave Gail axis and on the southside of Bolzano curl around Talvera river. Two on Iseo lake. One on Locarno Bellinzona Gravedona axis, the other Locarno Lugano Lecco axis end of a "ray manta shape". "Demoiselles coiffées" "piramidi di terra" or "erdpyramiden" are not randomly placed.
some rocks on top of piramidi di terra or erdpyramiden look like shattercone shapes http://www.pyramidencafe.it/deutsch.htm
Is Haughton like Verdon ? Is Kara Kul impact like Arvan ? Is Wells Creek a coffer shape impact ? Do Sierra Madera and Riess impacts have a forehead and a tail (with side valleys for Riess ?) ? Do Lawn Hill and Goat Paddock have a "ray manta shape with curled wings" ?
The southern Préalpes look complicated Ventoux impact (and Neville Price with lateral sedimentary volcanoes in "Major impacts and plate tectonics") shows that impact curls can induce mistakes and are not impacts (but there are also rebounds). Montagne de St Genis, Crête des Selles, montagne de Céüze, near Val de Durance have extraordinary shapes (like Chartreuse and Ventoux area) and the rocks are vertical in Sisteron [are diapirs an impact marker ?]! Seyne-les Alpes has a double ring with "clues de Chabrières" and "clues de Barles" have also vertical rocks. Is there a huge crater impact Durance-Bléone with an axis Coirons (basalt flood west of the Rhône) and Menton on the sea coast ? with symmetry Luberon and montagne de Lure versus Vercors south rim north of Die+Pic de Bure and Champsaur basi to the rear; Plan de Provence versus Ubaye, Durance and Larche pass in front ? explaining the French South Alps shapes ?
The "Guide géologique régional de Provence", p170-188, shows impact busting remainings for Auriol and Ste Baume, going straight to Marseille's old greek harbour and Château d'If, calanques (in La Spezia way : look at the faults on p386 in "Géologie de la France" tome 2 by Debelmas) ? Port-Miou calanque is related with a lateral arc as La Ciotat is. http://membres.lycos.fr/jgallay/calanques/ http://www.calanquesmarseille.com/ On page 386 in "Géologie de la France" tome 2 de Debelmas, the triasic "bande de Barjols" is aiming Marseille. North-east there is the Grand Plan de Canjuers and Verdon canyon. Eureka ! That's serious, in the Ventoux way, with the 20 km ovale Castellane http://www.lavaurs.com/fr/spot/0811/07 (with gypsum and salt as on St Laurent impact and Mars http://www.ggl.ulaval.ca/personnel/bourque/s2/sel.iles.madeleine.html http://scireview.de/mars/cataecr.htm http://scireview.de/mars/cataecc.htm ), Trigance, Combs-sur-Artuby, Bargème and pages 126-129 of Guide géologique régional de Provence are dreadful (vertically smashed rocks,scales...). Point Sublime, Gorges de la Mescla, Artuby canyon explain a push towards Marseille. This impact explain, related with Durance-Bléone major impact, also Moustiers-Ste Marie listric carving (as for Sault near Ventoux), plateau de Valensole and Pays de Thoard, Gréoux-les-Bains and Digne-les-Bains spas Maurice Gidon shows the wave related with Durance-Bléone major impact on http://www.geol-alp.com/gap_digne/_schemas/0_general_schemas/bloc_gap_barreme_5.gif on http://www.geol-alp.com/gap_digne/_gap_digne_general/0_nappe_digne.html and underlines the raughwacke under Digne spreading on http://www.geol-alp.com/gap_digne/_gap_digne_general/sudsasse_strati.html .] .

Mail 13/6/05 :
Can Alboran sea be a meteor impact crater ? You aren't the first one to ask that question! Personally I think not: the geology is consistent with an origin as a Mediterranean back-arc basin similar to the Tyrrhenian Sea, the Pannonian Basin, or the Aegean Sea. All of these have a roughly circular shape with arcuate thrust belts on one side: so if the Alboran Sea is an impact basin, why not the others? The Scotia arc/ Scotia sea, the Antilles arc/Caribbean Sea, the Marianas arc/Philippine sea, and many others, have a very similar geometry. So these could be impact basins too (I think GD Price and N Price suggested this for the Scotia Sea already). It makes for a lot of impact basins, all coincidently lying exactly on plate boundaries! [why not a catena ?]
If you want the Alboran Sea to be an impact basin, then it has to have formed at about 20 Ma (the age of the oldest sediments in the basin) [can it be a jetting coming back down in the crater or backthrusting ? the crater coming back on itself ?]. The thrust belt around it is mainly younger than this, from about 20 Ma to 6 Ma, which presents a problem. The magmatism in the basin is also mainly younger (mainly 15 - 6 Ma). Arguments ***for*** an impact origin include: 1) the olistostromes that form the oldest part of the basin fill, and also extend on land - age around 18 -20 Ma. 2) the "lithoclastic gneiss" that underlies the Ronda peridotite. This is a sheet of schist breccia with a melt matrix - now mainly crystallized as cordierite-bearing granite - which lies underneath the mantle rocks of the Ronda peridotite. Age is around 20 Ma. Could this be an impact melt sheet?
If flysch is an impact marker, Alboran sea is an impact ( see figure 6 of "Formation of arcuate orogenic belts in the western Mediterranean region" de Gideon Rosenbaum et Gordon S.Lister http://www.earth.uq.edu.au/rosenbaum/Rosenbaum_GSA_2004.pdf ).
What about arcs : Baïkal, Khangaï, Altaï, Iablonovy Mts, Zabchan, Selenga, Keroulen, Argoun, Aldan, rivers... ? What about the huge arcs in Saoudi Arabia Arabie Séoudite starting from Medina-Mecca ? Page 115 in "Comprendre et enseigner la planète terre" by Caron, Gauthier, Schaaf, Ulysse, Wozniak, 1989, there is a 50 km hole in the center of the Red Sea.
"Les impacts météoritiques" by Jehan Rondot, p42 and 142 : impacts induce ring depressions (Manicouagan and Charlevoix). Are Kola, Collinson, Prince-Albert, Wollasten, de Fox, Brodeur-Borden, peninsula and Roi Guillaume, Prince Charles, Roi-Mackensie, Ceylan or Danish islands, ring depressions ? Is Northern-Irland a double "astroblem country" with double impact : 1°) Belfast curl with Strangford Lough, 2°) Lough Neagh basin and Lough Foyle curl, Foyle, Donegal and Antrim, lough Erne and Ulster canal ? Do Norfolk-Suffolk, Käthiäwä, Rio de la Plata and Bahia Blanca , have the same kind of shape ?

«Géologie» by Paquet p101 notices helium in Massif Central, Alsace, Pyrénées, near Mediterranean Sea, in Hungary, in molassic basins of the Alps : is it related with impacts ?
Same for Arizona : "Arizona also has the thickest, youngest known bedded salt (NaCl) deposits in North America, if not the world. One deposit in the Red Lake Basin north of Kingman in Mohave County is estimated to contain more than 400 km3 (100 mi3) with thicknesses approaching 3,035 m (10,000 ft). West of Phoenix lies the Luke salt body, also thought to be about 3,035 m (10,000 ft) thick. Some scientists believe that the Picacho Basin near Eloy in south-central Arizona contains the thickest anhydrite sequence in the world. Anhydrite (CaSO4) is a gypsum-like mineral. The sequence consists of about 90 percent anhydrite and 10 percent interbedded shale and is slightly less than 1,820 m (6,000 ft) thick. Anhydrite is one of the evaporite minerals that form, under certain circumstances, when large volumes of water evaporate. The Pinta Dome east of Holbrook on the Colorado Plateau contains the only knowm helium field in the world where non-fuel gas has been commercially extracted. Normally, helium is a minor by-product in certain natural gas fields. But the Pinta Dome contains only helium and nitrogen."

Mail of 7/7/05 :
Thank you for the email. I have tried the link, and it is apparent that you have put much work into it. I will forward your work to other geologists here in the states and check into some of your suggested structures. Yes, impact craters have come a long way over the years.
We continue to research impact structures at the the University of Oklahoma, especially as they relate to oil and gas deposits.
The article link there, as you know, is http://www.edge.ou.edu/news.html [if the link is cutted click on http://www.google.com/search?hl=en&lr=&client=firefox-a&rls=org.mozilla%3Afr-FR%3Aofficial_s&q=%22Richard+DONOFRIO%22&btnG=Search ]. Some of the articles are updated periodically. We expect that, with the significant increase in oil and gas prices, that more drilling of potential astrobleme anomalies will occur.
No doubt you watched the comet impact the other day. Quite an accomplishment!
Who is going to sing the love of geographers for plate tectonics (and astroblems pepper grains in the mechanic)? The passion of systemicians for systemic ? Le Pichon, p77 of "Kaiko. Voyage aux extrêmités de la mer", speaks about his encounter with Mattauer as an « enchantement ».
