Late Paleozoic and Mesozoic continental sedimentation, northeastern North America; a symposium

Recently many nonmarine units in the conceptual framework of the northern Appalachians have been reinvestigated. Earlier work stressed regional paleogeography, cyclicity, and mineralogy; the modern approach is to combine sediment texture, primary structures, directional mapping, vertical sequences, and mineral composition to integrate their depositional mechanics and origin. In this volume are nine separately cited papers originally presented at the 1966 meeting of the Northeast Section of the Geological Society of America, which summarize these current investigations. These papers show that two basic continental sedimentation models occur in the northern Appalachians--the Coastal Plain and the Fault Trough.
