Map showing faults with Quaternary displacement, northeastern San Francisco Bay region, California
Edward J. Helley, Darrell G. Herd
1977, Miscellaneous Field Studies Map 881
This map shows faults with Quaternary displacement in the northeast San Francisco Bay region of California. Faults that have been historically active or that show evidence of movement during approximately the last 2 million years (the Quaternary Period) are delineated and are classified according to the age of their last...
The geological investigation of the Taurus-Littrow Valley: Apollo 17 landing site
Edward W. Wolfe, N. G. Bailey, B.K. Lucchitta, W.R. Muehlberger, D. H. Scott, R. L. Sutton, H. G. Wilshire
1977, Open-File Report 77-783
Astronauts Cernan and Schmitt, of Apollo 17, landed in the Taurus-Littrow valley of the Moon on December 11, 1972. Their major objectives were: (1) to sample very ancient lunar material such as might be found in pre-Imbrian highlands as distant as possible from the Imbrium basin, and (2) to sample...
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...
Geochemical and mineralogical studies of a South Texas roll-front uranium deposit
Martin B. Goldhaber, Richard L. Reynolds
1977, Open-File Report 77-821
Core samples from a roll-front uranium deposit in south Texas have been analyzed for iron sulfide content and mineralogy, organic carbon content and the abundance of carbonate, iron, manganese and titanium. Sulfide occurs almost exclusively as the iron disulfides pyrite and marcasite, in concentrations as high as 2 percent of...
Urban and regional land use change detected by using Landsat data
William J. Todd
1977, Journal of Research of the U.S. Geological Survey (5) 529-534
The Atlanta Regional Commission and the Earth Resources Observation Systems Data Center participated in a demonstration of the use of Landsat digital data to detect land use change in the Atlanta, Ga., area. Temporal overlays combining Landsat band-5 data from October 1972 and 1974 were made by using the General...
A radiometric interpretive legend for Landsat digital thematic maps
Charles J. Robinove
1977, Photogrammetric Engineering and Remote Sensing (43) 593-594
A legend is suggested for use with computer-generated thematic maps made from Landsat digital data that designates some of the radiometric characteristics of each thematic map unit as well as the described terrain attributes of each map unit. The relationship between spectral band and radiance for each map unit is...
