Description: This map from the U. S. Geological Survey Professional Paper 1403-C shows generalized geologic features of the southeastern United States, including the area of the Floridan aquifer system. The map shows the physiologic features of the coastal plain and the fall line or inner margin of the coastal plain. The map shows sedimentary rocks ranging in age from Paleozoic to Post-Miocene, and crystalline rock from Paleozoic to Precambrian. In Florida there are no crystalline rocks, and sedimentary rocks range from Post-Miocene to Lower Tertiary.
