Appalachian Maps & Diagrams


Map of the Appalachian Basin. This foreland basin accumulated Paleozoic sedimentary rocks of Early Cambrian through Early Permian age. North to south, the Appalachian Basin Province crosses New York, Pennsylvania, eastern Ohio, West Virginia, western Maryland, eastern Kentucky, western Virginia, eastern Tennessee, northwestern Georgia, and northeastern Alabama (After R. T. Ryder of USGS).

Appalachian Maps, Cross sections and Diagrams
 
The sources of maps, diagrams and photographic images have been referenced on that particular illustration. The Kentucky Geological Survey is a source of most of the measured sections for Route 23, while many of the maps and diagrams tracking continental paleogeography were created by Dr. Ron Blakey of Northern Arizona University at Flagstaff, Arizona; while the paleogeographic maps and cross sections for the late Paleozoic of the Appalachians were created by Dr. Lynn S. Fichter of the Department of Geology/Environmental Science of James Madison University in Harrisonburg, Virginia.
