Stages of Geological Evolution

The Sixteen Stages of Geological Evolution in Virginia
This 16 page history is a summary of the geological evolution of Virginia.  Additionally, we try to reconstruct what Virginia may have been like in the past, what sort of environments were dominant , and what the climate was like during each of the stages. Theoretically the simplest model for Virginia's geologic history is the Wilson Cycle; the opening and closing of an ocean basin. This cycle is implicit in the pages to follow, but is not dealt with directly. To get a quick review of the Wilson Cycle go here.
