Mississippian geology
Throughout both the Valley and Ridge and the Appalachian Plateau, the geology is dominated by a succession of Paleozoic sedimentary rocks deposited when eastern North America was flooded by the ancient Iapetus Ocean. The continent lay close to the equator, and sequences of shallow-marine limestone and shale were deposited with occasional incursions of deltaic or shallow-marine sandstone.Mapping of the surface geology in Texas is being done to provide a geologic map database and related basic geologic framework information that is sufficiently detailed (1:24,000 to 1:100,000) to serve as a primary data source for applied earth science investigations. Maps constructed during recent years address a variety of needs, …Patrick Wyse Jackson is a Professor in Geology and Curator of the Geological Museum.

A SUMMARY GEOLOGIC HISTORY OF THE ILLINOIS BASIN. David H. Swann. ABSTRACT. Nearly three miles of Paleozoic sediment, largely shallow water marine, fill the Illinois Basin.
