Major-element geochemistry of the Silent Canyon-Black Mountain peralkaline volcanic centers, northwestern Nevada Test Site: applications to an assessment of renewed volcanism
Bruce M. Crowe, Kenneth A. Sargent
1979, Open-File Report 79-926
The Silent Canyon and Black Mountain volcanic centers are located in the northern part of the Nevada Test Site. The Silent Canyon volcanic center is a buried cauldron complex of Miocene age (13-15 m.y.). Black Mountain volcanic center is an elliptical-shaped cauldron complex of late Miocene age. The lavas and...
Hydrologic data for urban studies in the Dallas, Texas, metropolitan area, 1977
B.B. Hampton, C.M. Wood
1979, Open-File Report 79-562
In August 1961, the Geological Survey, in cooperation with the city of Dallas, began a program of investigations designed to evaluate hydrologic factors affecting floods on several small streams in Dallas. During the 1977 water year, the original program was expanded to include the greater Dallas metropolitan area....
Geology of the Aspen 15-minute quadrangle, Pitkin and Gunnison counties, Colorado
Bruce Bryant
1979, Professional Paper 1073
The Aspen area, located 170 km southwest of Denver, Colo., lies at the intersection of the northeast-trending Colorado mineral belt and the west margin of the north-trending Sawatch uplift of Laramide age; it is within the southwest part of the northwest-trending late Paleozoic Eagle basin. Precambrian shales and graywackes, perhaps...
Sand dunes on the central Delmarva Peninsula, Maryland and Delaware

George H. Carlson, Kurt T. Gunard
1979, Open-File Report 79-1061
An investigation of flood flows from small drainage basins in Minnesota is being made to aid in the design of bridges, culverts and other highway drainage structures. Results of the investigation provide peak-flow data on streams generally with drainage areas less than 50 square miles, placing particular emphasis on those...
Preliminary catalog of earthquakes in northern Imperial Valley, California, October 1978-December 1978
V. Lamanuzzi, C.E. Johnson, P.T. German
1979, Open-File Report 79-930
The northern section of the Imperial Valley region in southern California is an area of known geothermal resources and high seismicity. To investigate the relationship between geothermal areas and earthquakes in the Imperial Valley, a 16-station seismic network was established in early 1973 by the U. S. Geological Survey. Six...
