Environmental conditions and resources of southwestern Mississippi
U.S. Geological Survey
1970, Report
The impending phase-out of Saturn V testing by the National Aeronautics and Space Administration at the Mississippi Test Facility (MTF) necessitates consideration of possible alternative uses for the Facility and surrounding region. To make a rapid and up-to-date study of pertinent environmental factors in that region, remote sensing techniques and...
Origin of the disturbed belt in northwestern Montana
Melville R. Mudge
1970, Article
The northern part of the disturbed belt in Montana is a northwesterly trending zone of closely spaced westerly dipping thrust faults, many folds, and some longitudinal normal faults and transverse faults. The theory of vertical uplift that results in gravitational gliding is a reasonable explanation of the origin of the...
Effects of local geology on ground motion near San Francisco Bay
Roger D. Borcherdt
1970, Bulletin of the Seismological Society of America (60) 29-61
Measurements of ground motion generated by nuclear explosions in Nevada were made for 37 locations near San Francisco Bay, California. The results were compared with the San Francisco 1906 earthquake intensities and the strong-motion recordings of the San Francisco earthquake of March 22, 1957. The recordings show marked amplitude variations...
Variations of major chemical constituents across the central Sierra Nevada batholith
P. C. Bateman, F. C. W. Dodge
1970, Bulletin of the Geological Society of America (81) 409-420
A study of 193 chemical analyses of plutonic rocks from 132 localities in the central Sierra Nevada shows convincingly that K2O decreases systematically westward and suggests that Fe2O3 and TiO2 may also decrease westward and that FeO, MgO, and CaO may increase. The ratio K2O/SiO2 obviously decreases westward across six of eight provisionally...
Petrogenesis of mylonites of high metamorphic grade in the Peninsular Ranges of southern California
Ted G. Theodore
1970, Bulletin of the Geological Society of America (81) 435-449
A fairly continuous, narrow belt of mylonite gneisses extends approximately 60 miles across southern California and crops out prominently at Coyote Mountain, near Borrego Springs, San Diego County. At Coyote Mountain, both prebatholithic rocks and igneous rocks lithologically similar to rocks from the nearby southern...
Sedimentary volumes and their significance
James Gilluly, John C. Reed Jr., Wallace M. Cady
1970, Bulletin of the Geological Society of America (81) 353-375
Sedimentary volumes are of prime interest in many fields of geology: as measures of erosional rates, of geochemical balance, and recently, with the virtual demonstration of continental drift, as measures of movement of the continental and oceanic plates.The Basement Map of the United States, published by the U.S. Geological Survey...
Nuclear methods applied to uranium geochemistry
J. N. Rosholt
1970, IEEE Transactions on Nuclear Science (17) 173-176
Stable and radioactive daughter products produced from nuclear disintegrations of uranium have proved useful in fundamental studies of the geochemistry of uranium in igneous rock and sedimentary environments and in ore deposits. Information gained from geochemical studies of uranium migration has been used to develop models...

Pedro, Livengood, and Tanana: A study of place-names near Fairbanks, Alaska
Paul J. Sorvo
1970, Names (18) 185-190
In the early hours of March 30, 1867, Secretary of State William H. Seward completed the purchase of the remote and unexplored land known as Russian America, or Alaska. Discovered in 1741 by Vitus Bering, Alaska progressed from a Czarist colony to a territory of the United States, and finally,...
Estimating steady-state evaporation rates from bare soils under conditions of high water table
C.D. Ripple, J. Rubin, T. E. A. Van Hylckama
1970, Report
A procedure that combines meteorological and soil equations of water transfer makes it possible to estimate approximately the steady-state evaporation from bare soils under conditions of high water table. Field data required include soil-water retention curves, water table depth and a record of air temperature, air humidity and wind velocity...
Water resources data for Indiana, 1969
Water Resources Division, U.S. Geological Survey
1970, Water Data Report IN-69-1
Surface-water records for the 1969 water year for Indiana, including records of streamflow or reservoir storage at gaging stations, partial-record stations, and miscellaneous sites, are given in this report and their locations shown in figures 1 and 3. Records for a few pertinent gaging stations in bordering States are also...

Aquilapollenites (Rouse) Funkhouser — Selected Rocky Mountain taxa and their stratigraphic ranges
Bernadine D. Tschudy, Estella B. Leopold
Robert M. Kosanke, Aureal T. Cross, editor(s)
1970, Book chapter, Symposium on palynology of the late Cretaceous and early Tertiary
The genus Aquilapollenites and its type species, A. quadrilobus, are redescribed, and the latter is illustrated. This report summarizes our present information on stratigraphic ranges of selected Rocky Mountain species and varieties of Aquilapollenites. Of the 17 taxa...
Geology and ground-water resources of Linn County, Iowa
Robert E. Hansen
1970, Water Supply Bulletin 10
Linn County, in east-central Iowa, covers about 713 square miles and lies in the Western Young Drift section of the Central Lowlands physiographic province. The normal annual rainfall in the county is about 88 inches and the annual mean temperature is about 48°F. The population in 1960 was 136,899, of...
Remote sensor application studies report, July 1, 1968 to June 30, 1969: Remote sensing reconnaissance, Mill creek area, Arbuckle Mountains, Oklahoma
L. C. Rowan, Terry W. Offield, Kenneth Watson, P. J. Cannon, R. D. Watson
1970, Report
As part of the U.S. Geological Survey's Remote Sensor Application Studies program, infrared images and several kinds of photographs were obtained on reconnaissance flights over two areas in the Arbuckle Mountains near Mill Creek, Oklahoma. These data were used in a preliminary investigation (1) to determine the diagnostic reflection and...
