Quaternary Nonglacial Geology

Includes 5 topical chapters covering paleoclimates, dating methods, volcanism, tephrochronology, and Pacific margin tephrochronologic correlation, and 15 chapters of regional synthesis covering: the Pacific margin; the Columbia Plateau; the Snake River Plain; the major pluvial lakes of the Great Basin; the Basin and Range in California, Arizona, and New Mexico; the Colorado Plateau; the Southern and Central Rocky Mountains; the Northern and Southern Great Plains, Osage Plains, and Interior Highlands; the Lower Mississippi Valley; the Gulf of Mexico Coastal Plain and Florida; the Appalachian Highlands and Interior Low Plateaus; and the Atlantic Coastal Plain. A large, full-color geologic map of the Quaternary deposits of the Lower Mississippi Valley, in addition to correlation charts, tables, and cross-sections relating to other chapters, is also included.

Abstract
The Atlantic Coastal Plain south of the glacial limit stretches 2,200 km from southeastern New York and northern New Jersey to the Florida Keys, and is as much as 320 km wide from the Piedmont to the continental slope (Figs. 1 and 2). It is divided into three subdivisions/belts that parallel the Atlantic Coast: the Upper (Inner), Middle, and Lower (Outer) Coastal Plains (Fig. 1). The subdivisions commonly are separated by escarpments and each subdivision has distinctive topography and surficial stratigraphy.
The Upper Coastal Plain is underlain by Cretaceous and Tertiary sediments that unconformably onlap Mesozoic to Precambrian rocks...
