Geology is the study of the earth and the processes which affect it. Because the earth is very complex, geology has many possible fields of study. Most geologists study a broad base of  topics and then  go on to specialize in one. This web site provides some additional information regarding some of the main fields of geology.

These fields include:
 

 

Fossils

Paleontology is the study of ancient life. Fossils are the traces left by these life forms, many of which no longer exist. Fossils may consist of bones, shells, imprints, molds, and casts that have been preserved in the rocks that geologists examine

Stratigraphy

Stratigraphy is the study of the relationships between stratified (layered) rocks. These relationships form the basis of deciphering geologic history. Each layer of rock provides clues to environment that existed when the layer was deposited. As changes in rock types occur from location this reveals a record of differing environment conditions. 

Rocks

Petrology is the study of rocks, their composition, and the conditions that lead to their creation. 

Caves

Karst - refers to  caves and the land forms created  as caves develop. In some place this field of study is critical because the collapse of caves can damage property. This is one aspect of the field of geology called geomorphology. Geomorphology is the study of land forms and the processes that create them.

Minerals

Mineralogy is the study of the building blocks of rocks (minerals). A mineral has a distinct chemical composition and structure. Minerals form under many different conditions and these conditions in turn are reflected in the type of mineral that forms. So by understanding minerals you can learn a lot about the environment when and where it formed.

Climate Change

Climate change is in some ways  a relatively new field of geologic study. Because of issues like global warming and degradation of the ozone layer, this field of study has become very important. But in actually it was always an important part of  geology; although it was not generally considered separately. The climate can help to determine what types of rocks and land forms can form. In turn geologic processes can change the climate, both locally  and globally.

Plate Tectonics 

The crust of the earth has been broken in to large pieces called plates. Plate Tectonics is the study of the movements that have occurred in the crust of the earth through time.


 

 
About the author

This page is still under construction. For now I am incorporating a lot of pictures of the fossils and rocks that I have collected, because I think this will make a useful reference for others who collect rocks and fossils. There is still a lot of information that I am going to add over time. 

My names for the rocks, minerals, and fossils are pretty much, my best guess using the references I have. If you see a rock, mineral, or fossil that you know is really something else I would appreciate it if you would let me know.
