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...
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...
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...
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...
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...
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...
Interpretation of an aeromagnetic strip across the northwestern United States
Isidore Zietz, B. Carter Hearn, Michael W. Higgins, G. D. Robinson, Donald A. Swanson
1971, Bulletin of the Geological Society of America (82) 3347-3372
This report discusses the results of aeromagnetic survey bounded by latitudes 45°30′ N. and 47°00′ N. and extending from the Rocky Mountains, to approximately 120 mi offshore in the Pacific Ocean. East of the Rocky Mountains, a larger area has been surveyed in the Great Plains bounded approximately by latitudes...
Small plate tectonics in the northeastern Pacific
Eli A. Silver
1971, Bulletin of the Geological Society of America (82) 3491-3496
Lithospheric plate motions in the northeastern Pacific were complicated at about 2.5 m.y. B.P. by the movement along a major northeast-trending fault cutting Cascadia Basin. An estimate of the slip rate along this fault gives critical information on the relative motions of four geometrically interdependent...
Upper Cenozoic basalts with high Sr87/Sr86 and Sr/Rb ratios, southern Great Basin, western United States
Carl E. Hedge, Donald C. Noble
1971, Bulletin of the Geological Society of America (82) 3503-3509
Upper Cenozoic basalts from southwestern Nevada and east-central California are unusually rich in both strontium (~ 1,200 ppm) and Sr87 (initial Sr87/Sr86 ~ 0.707). The average Rb/Sr ratio of these basalts is too low to have generated the observed Sr87/Sr86 ratio during the 4.6 b.y. of the Earth's...

Tertiary igneous chronology of the Great Basin of western United States — Implications for tectonic models
Edwin H. McKee
1971, Bulletin of the Geological Society of America (82) 3497-3501
The chronology of igneous activity in the Great Basin of western United States is used as a time framework for a simple plate model. This chronology suggests that a plate (Farallon plate) became underthrust to sufficient depth by the middle Tertiary to trigger the eruption...
