Gravity survey in part of the Snake River Plain, Idaho — A preliminary report
Harry L. Baldwin Jr., David P. Hill
1960, Open-File Report 60-11
During the early summer of 1959, a total of 1,187 gravity stations were occupied on the western part of the Snake River plain in Idaho. An area of 2,000 square miles extending from Glenns Ferry, Idaho, to Caldwell, Idaho, was covered with a station density of one station per two...
A comprehensive system of automatic computation in magnetic and gravity interpretation
R.G. Henderson
1960, Geophysics (25) 569-585
In the interpretation of magnetic and gravity anomalies, downward continuation of fields and calculation of first and second vertical derivatives of fields have been recognized as effective means for bringing into focus the latent diagnostic features of the data. A comprehensive system has been devised for the calculation of any or all of these...
Grid method of determining mean flow-distance in a drainage basin
M.W. Busby, M. A. Benson
1960, International Association of Scientific Hydrology - Bulletin (5) 32-36
The basin characteristics Σal or L ca are useful in hydrologic studies, but existing methods of determining them are either tedious or somewhat inaccurate. The grid method presented herein lessens the amount of tedious labor and provides an accurate measure of either Σal or L ca . An adaptation of the method could be used to compute the...
Transcurrent faulting and volcanism in Owens Valley, California
L. C. Pakiser
1960, Bulletin of the Geological Society of America (71) 153-160
In the Owens Valley region of California, volcanic activity of Cenozoic age was confined mainly to three areas near the ends of important faults. The volcanic eruptions seemingly took place in regions of relative tension, if the horizontal movement along these faults was left lateral. The deep depression of Owens Valley may have...
Foothills fault system, western Sierra Nevada, California
L. D. Clark
1960, Bulletin of the Geological Society of America (71) 483-496
A large fault system, here named the Foothills fault system, is the dominant structural feature of the western Sierra Nevada. The steeply dipping to vertical component faults trend northwestward through an area about 200 miles long and 30 miles wide north of 37°30' north latitude. The faulted Paleozoic and Mesozoic...
Glaciation of the east slope of Rocky Mountain National Park, Colorado
Gerald M Richmond
1960, Bulletin of the Geological Society of America (71) 1371-1382
The eastern slope of Rocky Mountain National Park, Colorado, has been subjected to at least three separate Pleistocene glaciations, which from oldest to youngest are correlated with the Buffalo, Bull Lake, and Pinedale glaciations of Blackwelder in the Wind River Mountains of Wyoming. In this area, deposits of the oldest glaciation are...
Mineral paragenesis of precambrian rocks in the Tenmile Range, Colorado
A. H. Koschmann
1960, Bulletin of the Geological Society of America (71) 1357-1370
A Precambrian complex of granulite, gneiss, and migmatite, intruded by numerous plutons of granitic rocks correlated with the Silver Plume granite, is exposed in a long narrow belt along the crest and upper slopes of the Tenmile Range, Colorado. The metamorphic rocks are predominantly felsic; bands, lenses, and irregular bodies of mafic rocks rich in biotite,...
Geophysical investigation of Mono Basin, California
L.C. Pakisek, F. Press, M. F. Kane
1960, Bulletin of the Geological Society of America (71) 415-448
Gravity and seismic studies in Mono Basin, Mono County, California, completed during the summer of 1957 revealed a large, roughly triangular block that had subsided about 18,000 ± 5000 feet and received an accumulation of about 300 ± 100 cubic miles of light clastic sediments and volcanic material of Cenozoic age....
