   HTML VERSION - A relatively large file that may take time to load depending on your modum speed - (clickable to pages in the 16 page history)

   PDF VERSION - pdf stands for "portable document file" and is created in Adobe Acrobat. It produces images that print and photocopy with virtually the same crispness as the original drawing. They are also larger than a typical html file and require an Adobe Acrobat reader to load.

     Clickable to other pages in the 16 page history.

     The model for Virginia's geologic history is based on the Wilson cycle, the opening and closing of an ocean basin. This cycle is implicit in the history, but the cycle is not dealt with directly. A one page summary of the history can be found at this link. For more details go to this link.
