Accessory opaque oxides from hybrid granitoid rocks of the southern Snake Range, Nevada
Donald E. Lee, Richard E. Van Loenen
1979, Open-File Report 79-1608
Analytical data are presented for 12 magnetite and 6 ilmenite samples recovered from hybrid granitoid rocks of the southern Snake Range, Nevada. The magnetites are unusual for their very low contents of TiO2 and for their similarity of composition over a range of petrologic types. The ilmenites are somewhat unusual...

Joel S. Leventhal
1979, Open-File Report 79-1503
Core samples from Devonian shales from five localities in the Appalachian Basin have been analyzed for major, minor, and trace constituents. The contents of major elements are rather similar; however, the minor constituents, organic C, S, PO4, and CO3, show variations by a factor of 10. Trace elements Mo, Ni,...
Geologic description of selected strong-motion accelerograph sites, Part II
B.L. Silverstein
1979, Open-File Report 79-428
One of the major tasks of the U.S. Geological Survey as regards seismic engineering is the collection and dissemination of strong-motion accelerograph records. When analyzing these records certain information describing the instrument site is important: local geology; instrument housing (buildings, dams, bridges, instrument shelters, etc.); local topography; and proximity of...

1979, Open-File Report 79-1190
The largest and most productive mine in Saudi Arabia in ancient and modern times has been Mand adh Dhahab. Country rocks in the district are pyroclastic and clastic rocks that belong to the Halaban group of late Precambrian age. From oldest to youngest, the units are: andesite, lower agglomerate, lower...
Organic matter and sandstone-type uranium deposits: a primer
Joel S. Leventhal
1979, Open-File Report 79-1310
Organic material is intimately associated with sandstone-type uranium deposits in the western United States.. This report gives details of the types of organic matter and their possible role in producing a uranium deposit. These steps include mobilization of uranium from igneous rocks, transportation from the surface, concentration by organic matter,...

Near-surface heat flow in Saline Valley, California
Charles W. Mase, S.P. Galanis, Robert J. Munroe
1979, Open-File Report 79-1136
With the exception of values from one borehole drilled at Palm Spring and three boreholes drilled around Saline Valley dry lake, eight new heat-flow values in Saline Valley, California, are within or somewhat below the range one would expect for this region of the Basin and Range heat-flow province. The...
Hydrologic data for urban studies in the Fort Worth, Texas, metropolitan area, 1977
R.M. Slade Jr., J.M. Taylor, D.L. Haynes
1979, Open-File Report 79-216
Hydrologic investigations of urban areas in Texas were begun by the U.S. Geological Survey in 1954. These investigations are now in progress in several major metropolitan areas including Austin, Dallas, Dallas County, Fort Worth, Houston, and San Antonio.In October 1968, the Geological Survey, in cooperation with the city of Fort...
