Studies in Tertiary stratigraphy of the California Coast Ranges
Earl E. Brabb, editor(s)
1983, Professional Paper 1213
The correlation of rocks of Paleogene age in California with those in Europe has had a long and complex history that can only be highlighted here. Kleinpell (1938, p. 168-181), in his classic work defining Miocene benthic1 foraminiferal stages of California, attempted to correlate faunas of California with those of...
Mineral resource potential map of the Dolly Ann Roadless Area, Alleghany County, Virginia
Frank G. Lesure, Jay G. Jones
1983, Miscellaneous Field Studies Map 1358-D
The Dolly Ann Roadless Area comprises 7,900 acres (3,200 ha) in the George Washington National Forest in the Valley and Ridge physiographic province of west-central Virginia. The area is at the southern ·end of Warm Springs Mountain in Alleghany County just northeast of Covington, the county seat (index map). U.S....
Hydrogeology for land-use planning: the Peters Creek area, Municipality of Anchorage, Alaska
Jilann O. Brunett, Michael Lee
1983, Water-Resources Investigations Report 82-4120
Wells currently provide all water supplies in the area. Most wells obtain enough water for individual household needs from unconsolidated, principally glacial and glacioalluvial deposits. In some places, however, wells must be drilled into the underlying bedrock to obtain adequate supplies. It may be possible to develop small community supplies--for...
Potentiometric surface of the Floridan Aquifer and its use in management of water resources, St. Johns River Water Management District, Florida
Harry George Rodis, D.A. Munch
1983, Water-Resources Investigations Report 83-4176
The Floridan aquifer supplies most of the fresh groundwater for municipal, industrial, and agricultural uses within the 12,400 sq mi St. Johns River Water Management District. Because of the growing demand for water and the variation in rainfall, resource managers need timely information on short-term and long-term changes in the...
Summary of Tertiary investigations in western Saudi Arabia, current work by the U.S. Geological Survey and recommended future studies
Donald G. Hadley, Dwight Lyman Schmidt, Robert Griffin Coleman
1983, Open-File Report 83-487
In 1936, geologic work related to the Tertiary System in western Saudi Arabia began with a study of the Umm Gerad barite deposit by K. S. Twitchell. In 1944, a study focusing specifically on Tertiary rocks was conducted by Steineke and others near Jiddah. Small-scale mapping of Tertiary sequences began...
Preliminary map of limonitic hydrothermal alteration for portions of the Needles 1° x 2° quadrangle, Arizona and California
Gary L. Raines
1983, Open-File Report 83-421
Portions of the Needles quadrangle have been designated by the Bureau of Land Management as potential wilderness areas and are being evaluated by a multidisciplinary team to determine the mineral-resource potential. As a part of this study Landsat images are being used to map the generalized distribution of limonitic materials...
A microcomputer-based data acquisition and control system for the direct shear, ring shear, triaxial shear, and consolidation tests
Philip S. Powers
1983, Open-File Report 83-491
This report is intended to provide internal documentation for the U.S. Geological Survey laboratory's automatic data acquisition system. The operating procedures for each type of test are designed to independently lead a first-time user through the various stages of using the computer to control the test. Continuing advances in computer...
Reconnaissance geology of the Thaniyah Quadrangle, sheet 20/42 C, Kingdom of Saudi Arabia
Robert C. Greene
1983, Open-File Report 83-448
The Thaniyah quadrangle, sheet 20/42 C, is located in the transition zone between the Hijaz Mountains and the Najd Plateau of southwestern Saudi Arabia between lat 20?00' and 20?30' N., long 42?00' to 42?30' E. The quadrangle is underlain by Precambrian metavolcanic, metasedimentary, plutonic, and dike rocks. Metavolcanic rocks consist...
