Salt structure and sediment thickness, Texas-Louisiana continental slope, northwestern Gulf of Mexico
Raymond G. Martin Jr.
1973, Open-File Report 73-179
The objectives of this study were to determine the general configuration of the salt surface beneath the Texas-Louisiana continental slope and to isopach the Mesozoic-Cenozoic sedimentary section lying upon it. The structure contour map discloses that the entire slope province between the shelf edge and Sigsbee Escarpment is underlain by salt...
Measurement of lateral erosion at proposed river crossing sites of the Alaskan pipeline
James Brice
1973, Open-File Report 73-31
This study of lateral erosion rates by comparison of aerial photographs was undertaken at the request of D. M. Culbertson, hydraulic engineer, U.S. Geological Survey, Menlo Park, Calif., and preparatory work in Alaska (during June 1-18, 1971) was done with the cooperation of Harry Hulsing, district chief, Alaska District. Examination...
Atlas of Mars, Memnonia quadrangle, MC-16
United States Geological Survey
1973, Open-File Report 73-332
This mosaic was made with Mariner 9 pictures provided by the Jet Propulsion Laboratory (JPL), California Institute of Technology. The Image Processing Laboratory (IPL) of JPL processed the digital pictures to remove image artifacts and geometric distortions, to enhance high-frequency topographic detail while subduing low-frequency albedo variation, and to transform...
Catalog of earthquakes along the San Andreas fault system in Central California, April-June 1972
R. L. Wesson, R.E. Bennett, F.W. Lester
1973, Open-File Report 73-361
Numerous small earthquakes occur each day in the coast ranges of Central California. The detailed study of these earthquakes provides a tool for gaining insight into the tectonic and physical processes responsible for the generation of damaging earthquakes. This catalog contains the fundamental parameters for earthquakes located within and adjacent...
Barite in Pakistan
F.L. Klinger, R.L. Richards
1973, Open-File Report 73-145
Before 1953 almost no barite deposits were known in Pakistan. Discovery of such deposits relatively close to oil fields in northern Pakistan in 1953 led to increased barite production from 1957 to 1961 and to doubling of production in 1962, firmly establishing new industry for the country. During 1962 and...
