Strain in southern California: Measured uniaxial north-south regional contraction
J.C. Savage, W.H. Prescott, M. Lisowski, N. King
1978, Science (202) 883-885
The plate tectonics model of the Pacific moving northwest relative to North America implies that the regional strain in California should be simple shear across a vertical plane striking N45°W or equivalently equal parts of north-south contraction and east-west extension. Measurements of the strain accumulation at seven separate sites in...

Wendell A. Duffield, George I. Smith
1978, Journal of Research of the U.S. Geological Survey (6) 395-408
During pluvial periods of the Pleistocene and Holocene, a large river flowed south from Owens Lake to China Lake between the Sierra Nevada and the Coso Range. The most recent channel, dry during historic time, is clearly marked by cliffs and falls. An older, now-abandoned part of the channel beneath...
Occurrence and formation of avicennite, Tl2O3 , as a secondary mineral at the Carlin gold deposit, Nevada
Arthur S. Radtke, Frank W. Dickson, John F. Slack
1978, Journal of Research of the U.S. Geological Survey (6) 241-246
Avicennite, Tl2O3, occurs as grains disseminated in silicified limestones in the upper part of the East ore zone of the Carlin gold deposit, Nevada. The avicennite is formed by the oxidation of carlinite, Tl2S, found in primary unoxidized carbonaceous ore immediately below the avicennite. The grains of avicennite closely...
Stable isotope studies of bedded barite at East Northumberland Canyon in Toquima Range, central Nevada
R. O. Rye, D. R. Shawe, F. G. Poole
1978, Journal of Research of the U.S. Geological Survey (6) 221-229
Several beds of barite occur in the Slaven Chert at East Northumberland Canyon in the Toquima Range of central Nevada. Most of the barite is internally laminated but shows massive weathering. However, rosette, disseminated, conglomeratic, and concretionary varieties also occur. New fossil evidence from conodonts and brachiopods indicates a Late...

Lucy M. Force, George K. Moncure
1978, Journal of Research of the U.S. Geological Survey (6) 203-214
Sedimentary clay that crops out in the coastal plains of New Jersey, Delaware, the part of Maryland north and east of Washington, B.C., and the northeast half of Washington, D.C., in the nonmarine Cretaceous Potomac Group is predominantly kaolinite and illite. In contrast, in part of southeastern Maryland, the...
A tuya in Togiak Valley, Southwest Alaska
J. M. Hoare, W. L. Coonrad
1978, Journal of Research of the U.S. Geological Survey (6) 193-201
The shape, composition, structure, and location of a conspicuous flat-topped mountain in the lower Togiak Valley, southwest Alaska, all indicate that it formed by a subglacial volcanic eruption of olivine basalt. Volcanoes of this type are known as "tuyas." The Togiak tuya erupted into an intraglacial lake in a hole...

E.J. Pluhowski, A. G. Spinello
1978, Journal of Research of the U.S. Geological Survey (6) 263-271
Statistically significant decreases in the ratio of base flow to total flow of streams along the south shore of Long Island, N.Y., are due to the use of expanding storm-sewer and sanitary-sewer networks. Base-flow losses due to sewering ranging from virtually none at Connetquot River (largely unaffected by urban development)...
