Magnetic Titanohematite Minerals in Uranium-Bearing Sandstones
Richard L. Reynolds
1977, Open-File Report 77-355
Detrital grains of the rhombohedral ilmenite (FeT1O3)--hematite (Fe2O3) solid solution series (titanohematites) have been identified by thermomagnetic, reflection microscopic, and X-ray diffraction analysis in six uranium-bearing sandstones in the western United States. Many of the titanohematites are ferrimagnetic and have Curie temperatures ranging from about 70 Deg C to 220...
Review and analysis of hydrogeologic conditions near the site of a potential nuclear-waste repository, Eddy and Lea counties, New Mexico
Jerry W. Mercer, Brennon R. Orr
1977, Open-File Report 77-123
This interim report reviews and summarizes the hydrogeology of rocks associated with the Permian salt beds (Castile and Salado Formations) of Los Medanos area in southeastern New Mexico. The information will be considered, together with other factors, in the preparation of an analysis of the impact of a potential nuclear-waste...
Appraisal of the water resources of Death Valley, California-Nevada
Glenn Allen Miller
1977, Open-File Report 77-728
The hydrologic system in Death Valley is probably in a steady-state condition--that is, recharge and discharge are equal, and net changes in the quantity of ground water in storage are not occurring. Recharge to ground water in the valley is derived from interbasin underflow and from local precipitation. The two...

Uranium in Precambrian granitic rocks of the St. Francois Mountains, southeastern Missouri, with comments on uranium resource potential
J. Thomas Nash
1977, Open-File Report 77-787
Red granites of the St. Francois Mountains are highly radioactive and contain 4 to 34 parts per million (ppm) uranium. The most radioactive is the Graniteville Granite which contains an average of 16.9 ppm U and 42.6 ppm Th. The Butler Hill and Breadtray Granites also contain anomalous amounts, averaging...
Summary of basic hydrologic data collected at Coso Hot Springs, Inyo County, California
W. R. Moyle
1977, Open-File Report 77-485
More than 200 wells and springs were visited within a 20-mile radius of Coso Hot Springs, Calif. Hydrologic and geothermal data were collected for each well or spring site. The data includes depth, chemical quality, temperature and specific conductance of water, quantity of flow, well construction, and well logs. These...
Preliminary analysis of lineaments and engineering properties of bedrock, Penobscot Bay area, Maine
Fitzhugh T. Lee, Dennis W. O’Leary, Sharon F. Diehl
1977, Open-File Report 77-886
A remote sensing study of coastal and near coastal Maine was undertaken to identify bedrock features of possible importance to construction. Major lineaments were identified that separate the region into four distinct terrains. Within each terrain, smaller lineaments and other physiographic features show distinctive and consistent patterns, reflecting similarities in...
Water resources of the Barona, Capitan Grande, and Sycuan Indian Reservations, San Diego County, California
W. R. Moyle, R.L. Blazs
1977, Open-File Report 77-289
The Barona and Capitan Grande Indian Reservations, California, have sufficient water to satisfy present (1976) domestic and stock needs; however, the Sycuan Indian Reservation is experiencing a shortage of water for domestic supply because of the decline of the water table beneath the reservation well field and a general decline...

Calcic soils and calcretes in the southwestern United States
George Odell Bachman, Michael N. Machette
1977, Open-File Report 77-794
Secondary calcium carbonate of diverse origins, 'caliche' of many authors, is widespread in the southwestern United States. 'Caliche' includes various carbonates such as calcic soils and products of groundwater cementation. The term 'caliche' is generally avoided in this report in favor of such terms as calcrete, calcic soils, and pervasively...

Seismicity of the Pahute Mesa area, Nevada Test Site: 8 October 1975 to 30 June 1976
A. M. Rogers, Geraldine M. Wuollet, P. A. Covington
1977, Open-File Report 77-826
A total of 1,075 earthquakes occurred in the Pahute Mesa area with 2.5≤ML≤4.9 during the period October 28, 1975, to June 28, 1976. The majority of these earthquakes are aftershocks of the nuclear events, Kasseri, Inlet, Muenster, Fontina, Cheshire, Estuary, Colby, and Pool (5.8≤ML≤6.3). Smaller nuclear events (ML≤5.5) on Rainier...

1977, Open-File Report 77-308
An assessment of water use in 1975 in the 39 counties and 62 Water Resources Inventory Areas of Washington, indicated that 2.49 trillion gallons of water was used for municipal, industrial, and irrigation purposes. That amount represents a 10-percent increase over a similar water-use assessment in 1965, but a slight...
Radioelement concentrations and preliminary radiometric ages of rocks of the Kigluaik Mountains, Seward Peninsula, Alaska

1977, Open-File Report 77-735
A sequence of old metamorphic rocks including the Kigluaik and Nome Groups is exposed in the Kigluaik Mountains of the Seward Peninsula. The high-grade metasedimentary rocks give a whole-rock Rb-Sr age of 735 m.y. This late Precambrian age is believed to be the time of metamorphism. Orthogneisses, intrusive into the...
