Late Mesozoic and Cenozoic Stratigraphic and Structural Framework Near Hopewell, Virginia

Description: From introduction: This study was undertaken as part of the U.S. Geological Survey's (USGS) Reactor Hazards Reduction Program. One of the goals of this program is to contribute to the growing recognition and cataloging of Cenozoic faults in the Atlantic Coastal Plain. Once the faults are recognized and cataloged, the stress field and resulting tectonic framework that produced these faults can be determined. This study defines the stratigraphic and structural relationships of a tectonically anom… more

Stratigraphic Nomenclature of the Central Santa Monica Mountains, Los Angeles County, California

Description: From abstract: The stratigraphic nomenclature of the central Santa Monica Mountains is revised to conform with present knowledge of the age, distribution, and stratigraphic relations of about 35 bedrock units. The revision is based on 1:12,000-scale mapping of the entire stratigraphic sequence and its facies, the position and stage assignment of abundant fossils, and contact relations.

Revisions in Stratigraphic Nomenclature of the Columbia River Basalt Group

Description: From abstract: New stratigraphic nomenclature for units within the Columbia River Basalt Group is introduced to revise and expand that currently in use; it is based largely on subdivisions made informally by T. L. Wright, M. J. Grolier, and D. A. Swanson in 1973. The Yakima Basalt is raised to subgroup status, and three formations-the Grande Ronde Basalt, Wanapum Basalt, and Saddle Mountains Basalt, in order of decreasing age-are defined within it.

Nomenclature of Precambrian Rocks in Colorado

Description: Abstract: "The Precambrian rocks of Colorado consist of a metaphoric complex more than 1,700 million years in age, three groups of igneous rocks about 1,700, 1,400, and 1,000 million years in age, here designated informal age groups, and two areally restricted units of sedimentary rocks, one between 1,400 and 1,700 million years in age and one between 950 and 1,400 million years. A systematic nomenclature for many of the rocks does not exist, but the present state of knowledge will permit estab… more
