Glen F. Brown
1971, Open-File Report 71-57
In 1963, in response to a request from the Ministry of Petroleum and Mineral Resources, the Saudi Arabian Government and the U. S. Geological Survey, U. S. Department of the Interior, with the approval of the U. S. Department of State, undertook a joint and cooperative effort to map and...
ERTS-A: a new apogee for mineral finding
William D. Carter
1971, Mining Engineering (23) 51-53
The EROS Program will continue investigations to select or develop optimum, economical airborne and space systems that will expand man's ability to observe and profit from natural resources. It is to be hoped that several of these systems will eventually prove useful supplements to current and developing mineral exploration technology....

Availability of ground water for public-water supply in the Pensacola area, Florida: interim report, June 1971
Henry Trapp Jr.
1971, Open-File Report 72-002
Statement of the problem Earlier hydrologic studies show that ample quantities of soft water of low dissolved solids content are obtainable from the sand-and-gravel aquifer in the Pensacola area. Some wells drilled for the city of Pensacola have yielded water with unacceptably high amounts of iron and carbon dioxide, and wells...
Palynology, age, and correlation of the Wanship Formation and their implications for the tectonic history of northeastern Utah
Douglas J. Nichols, M.A. Warner
1971, Geology (6) 30-33
Although never formally introduced, the stratigraphic name Wanship Formation has become entrenched in the literature; recently, misunderstanding of its age and correlation has led to invalid interpretations of the structural evolution of northeastern Utah. The basal Wanship conglomerate has been erroneously correlated with a conglomerate within the Frontier Formation at Coalville. The Coalville section has been dated as Cenomanian-Coniacian. The Wanship Formation at its "type locality"...
Water resources data for Indiana, 1970
Water Resources Division, U.S. Geological Survey
1971, Water Data Report IN-70-1
Water resources data for the 1970 water year for Indiana, including records of streamflow or reservoir storage at gaging stations, partial-record stations, and miscellaneous sites, and records of water-quality data on the chemical and physical characteristics of surface-water are given in this report. Records for a few pertinent gaging and...

The acoustic streamflow-measuring system on the Columbia River at The Dalles, Oregon
Winchell Smith, Larry L. Hubbard, Antonius Laenen
1971, Report
Records of discharge on the Columbia River at The Dalles, Oreg., are vital to the management of the complex water-development projects in the Columbia River basin. Accurate discharge figures are needed for consistent day-to-day management and are required to meet treaty obligations with Canada. Because dams have been erected that completely...
Interstitial water studies on small core samples, deep sea drilling Project, leg 7
F.L. Sayles, Frank T. Manheim
1971, Initial reports of the Deep Sea Drilling Project (7) 871-881
The sediments cored on Leg 7 are predominantly deep sea biogenic oozes and chalks; only rarely were significant quantities of pelagic clays and volcanic detritus encountered. The biogenic sections include both siliceous and calcareous deposits. At three sites the drilling terminated in basalt, one of which (Site 62) is interpreted...

Precipitation depth-duration-frequency relations for the San Francisco Bay region, California, with isohyetal map of San Francisco Bay region, California, showing mean annual precipitation
S. E. Rantz
1971, Basic Data Contribution 25
Precipitation depth-duration-frequency relations have been derived for the San Francisco Bay region, California. The regimen of precipitation in the region is such that depth-duration-frequency characteristics for a site are closely related to the mean annual precipitation for that site....

Comparative acute oral toxicity of pesticides to six species of birds
Richard K. Tucker, M. A. Haegele
1971, Toxicology and Applied Pharmacology (20) 57-65
Acute oral LD50 values were determined for 16 common pesticides on mallard ducks (Anas platyrhynchos), ring-necked pheasants (Phasianus colchicus), chukar partridges (Alectoris graeca), coturnix quail (Coturnix coturnix japonica), common pigeons (Columba livia), and house sparrows (Passer domesticus). Analyses of the data revealed that...
On the nature of the Boulder Batholith of Montana
M. R. Klepper, G.D. Robinson, H.W. Smedes
1971, Geological Society of America Bulletin (82) 1563-1580
In a recent review of the nature of batholiths, Hamilton and Myers (1967) interpreted the Boulder batholith of western Montana to be "in effect a gigantic mantled lava flow .... only a few kilometers thick," that flowed, under a crust of its own ejecta, across a broad structural basin. Such...
Structural implications of an offset Early Cretaceous shoreline in northern California
D. L. Jones, W. P. Irwin
1971, GSA Bulletin (82) 815-822
Recognition of a nonmarine to marine transition in sedimentary rocks at Glade Creek and Big Bar in the southern Klamath Mountains permits reconstruction of the approximate position of a north-trending Early Cretaceous (Valanginian) shoreline. At the southern end of the Klamath Mountains, the shoreline is displaced 60 mi or more...
Paleozoic metasediments in the northern Ruby Mountains, Nevada
Keith A. Howard
1971, GSA Bulletin (82) 259-264
New evidence indicates that high-grade regionally metamorphosed marble and quartzite in the northern Ruby Mountains are Paleozoic strata. Correlation is based on a match of the lithologic sequence to strata of Cambrian to Devonian age in nearby areas; particularly diagnostic is a brown dolomite at the...
The earthquake sequence near Danville, California, 1970
W.H.K. Lee, M.S. Eaton, E. E. Brabb
1971, Bulletin of the Seismological Society of America (61) 1771-1794
Several thousand small earthquakes, with magnitudes ranging up to 4, occurred near Danville, California, during May, June, and July 1970. Seven temporary seismographs were installed near the epicentral region to augment an existing telemetered network within 1 day after the first felt earthquake. The dense concentration of 10 seismographs within...
Impact breccias in carbonate rocks, Sierra Madera, Texas
H. G. Wilshire, Keith A. Howard, Terry W. Offield
1971, GSA Bulletin (82) 1009-1018
Two main types of deformational breccia occur in the Sierra Madera cryptoexplosion structure: monolithologic breccias composed of shattered rock of a single lithology and mixed breccias composed of rocks of several lithologies. Monolithologic breccias generally show no mineralogic signs of shock deformation, but a few samples are shatter-coned in a...
Investigations at active volcanoes
Thomas L. Wright
1971, Eos, Transactions, American Geophysical Union (52) 57-62
The field of volcanology has expanded greatly in the years 1967–1970, and work on active volcanoes has kept pace with this expansion. I have restricted this summary and the accompanying bibliography to studies by U.S.‐based investigators of active or potentially active volcanoes. I have been immeasurably aided in writing this...
Origin of the differentiated and hybrid lavas of Kilauea Volcano, Hawaii
Thomas L. Wright, Richard S. Fiske
1971, Journal of Petrology (12) 1-65
Kilauea Volcano has erupted lava from its summit caldera and from two rift zones that extend from the summit towards the east and south-west. Lavas erupted from the summit of the volcano differ from each other principally in their content of olivine and define lines of ‘olivine control’ on magnesia...
