COGEOMAP; a new era in cooperative geologic mapping

A program of cooperative geologic mapping was established between the U.S. Geological Survey and the State geological surveys in fiscal year 1985. The main purpose of the program is to increase general-purpose geologic mapping throughout the Nation. By combining State and Federal resources for geologic mapping through this cooperative program, new mapping has been started, and both geologic and geophysical maps that resulted from the program have already been published. The program grew from mapping projects in 18 States in fiscal year 1985 to a program involving 29 States in 1986, as the combined State and Federal resources in the program grew from about $2 million to nearly $3 million. As the program enlarges its scope, it faces the challenge of producing high-quality maps with uniform standards while promoting the use of new technologies to increase the speed of geologic and geophysical mapping and map production.

A lithologic log of the Oak Grove core, northeastern Virginia

The Oak Grove core was taken as part of a multifaceted project to develop a stratigraphic and tectonic framework for the Rappahannock drainage basin, northeastern Virginia. This core is at present the only continuously cored Cretaceous and Tertiary section on the Northern Neck of Virginia and is one of the few deep cores in the entire Salisbury embayment. The core includes most of the Chesapeake Group sediments (Miocene part) in the Oak Grove area, the Pamunkey Group (Paleocene and Eocene) and nearly all of the Potomac Group (Lower Cretaceous part) (see Table 1).

Preliminary report on Belair Exploratory Trench No. 10-76 near Augusta, Georgia

The Belair Exploratory Trench #10-76 was dug in October,1976, for the purpose of testing the conclusions of Prowell, O'Connor, and Rubin, 1975, and O'Connor and Prowell, 1976, concerning the time of latest movement along the Belair fault zone. The trench site is located 800 meters (2600 ft.) S27°W of the old Belair railroad station on U.S. Route 1 & 78 (see inset on Plate 1) in the southernmost clay pit of the Georgia Vitrified Brick and Clay Company. The trench was oriented almost nor-mal to the strike of the Belair fault zone (N27°E) about 100 meters (330 ft.) south of the trench exposure reported by Prowell, O'Connor, and Rubin, 1975. In this report, we are maintaining the terminology of Prowell, O'Connor, and Rubin, 1975, in defining the main fault as the fault that juxtaposes the crystalline phyllites and the Coastal Plain sediments (Plate 1 - at meter 106). Similarly, we refer to the eastside of the Belair fault zone as the upblock and the west side as the downblock.
