Basin and range structure: A system of horsts and grabens produced by deep-seated extension
John H. Stewart
1971, Bulletin of the Geological Society of America (82) 1019-1043
Basin and Range structure can be interpreted as a system of horsts and grabens produced by the fragmentation of a crustal slab above a plastically extending substratum. According to this view, the extension...

F. K. Miller, Edwin H. McKee
1971, Bulletin of the Geological Society of America (82) 717-722
Thrust and strike-slip faulting are recognized in the Plomosa Mountains, southwestern Arizona. The distribution of rock types and the geometry of the thrust faults necessitate that the upper plate moved from east to west. The amount of displacement is not known, but is considered to...

Max D. Crittenden Jr., Frederick E. Schaeffer, D. E. Trimble, Lee A. Woodward
1971, Bulletin of the Geological Society of America (82) 581-602
Recent stratigraphic studies in three widely separated localities in southeastern Idaho and western Utah have revealed a startling continuity of both individual rock units and of rock sequences over a distance of some 300 mi parallel to the strike of a late Precambrian and Cambrian depositional trough. Between 15,000 and...
Coronadite — Modes of occurrence and origin
D. F. Hewett
1971, Economic Geology (66) 164-177
The lead manganate, "coronadite," was first recognized at the Coronado mine in the Morenci district, Arizona, by Lindgren in 1903. Several years later, the identity of the mineral was questioned and it was not until 1932 that Orcel recognized it in material from Morocco. Since...

Thin skin distension in Tertiary rocks of southeastern Nevada
R. Ernest Anderson
1971, Bulletin of the Geological Society of America (82) 43-58
Volcanic rocks of late Tertiary age, aggregating about 17,000 ft, accumulated on a surface of low relief cut on Precambrian rocks in the Basin and Range province south of Lake Mead, in Nevada and Arizona. They consist mostly of lava and flow breccia of intermediate composition with minor ash-flow tuff,...

1971, Geological Society of America Bulletin (82) 2187-2208
A composite map of detailed aeromagnetic surveys over the midcontinent gravity high provides coverage of the 600-mi-long buried belt of mafic rocks of the Keweenawan Series from their outcrop localities in Minnesota and Wisconsin through Iowa and Nebraska. A map of the subsurface extent of the mafic rocks, based on...

An annotated bibliography of fauna and flora described from the Dockum Group of Triassic age in eastern New Mexico and West Texas
James C. Wright, Warren I. Finch
1971, Open-File Report 71-333
This annotated bibliography was prepared by Warren I. Finch from a rough copy compiled by the late James C. Wright in either late 1967 or early 1968 as an aid to his understanding of the stratigraphic distribution of uranium deposits in Triassic rocks of the Southern high Plains. He did...
Geology and ground water resources of Wells County, North Dakota
John P. Binemie, George A. Falgle, Ronald J. Bred, John R. Reid, Frank Buturla Jr.
1970, Bulletin 51
Wells County is in east-central North Dakota on the eastern flank of the Williston Basin. It is underlain by 4000 to 6000 feet of Paleozoic and Mesozoic rocks that dip gently to the west. The uppermost Cretaceous rocks, the Hell Creek, Fox Hills and Pierre Formations, lie directly beneath the...
Geology and ground water resources of Grand Forks County
Dan E. Hansen, Jack Kume, T. E. Kelly, Q.F. Paulson
1970, Bulletin 53
Grand Forks County in northeastern North Dakota is underlain by glacial drift, westward-dipping Paleozoic and Mesozoic sedimentary rocks and Precambrian igneous and metamorphic rocks. Glacial drift that covers the bedrock reaches a maximum thickness of 455 feet. It can be differentiated into 5 drift sheets, each of which in turn...
Geology and ground water resources, Williams County, North Dakota
Theodore F. Freers, C. A. Armstrong
1970, North Dakota Geological Survey Bulletin 48
Williams County, in northwestern North Dakota, is located near the center of the structural and sedimentary Williston basin. The preglacial sedimentary formations beneath the county are as much as 14,828 feet thick. Their beds dip generally to the south except along the flanks of the north-south striking Nesson anticline in...
Hydrogeologic data for the lower Housatonic River basin, Connecticut
I.G. Grossman, William E. Wilson
1970, Connecticut Water Resources Bulletin 20
This report contains hydrologic and geologic data collected for an investigation of the lower Housatonic River basin by the U.S. Geological Survey in financial cooperation with the Connecticut Water Resources Commission. The report also summarizes data that are available in other publications. The towns within the 557 square mile area...
Base-flow study of East River basin Brown and Calumet counties, Wisconsin
Robert W. Devaul
1970, Report
Streams in the East River basin gain ground water throughout most of their reaches, however, ground-water pumping of the Green Bay - DePere area may reduce the water being gained by the streams from ground water. The August 13, 14 measurements were made during base-flow period when flow duration was...

Relationship between subsidence and volcanic load, Hawaii
J.G. Moore
1970, Bulletin Volcanologique (34) 562-576
A computer analysis of tide-gage records in the northeast Pacific indicates that the active volcanic islands of eastern Hawaii are subsiding at a rate considerably faster than the eustatic rise of sea level. The rate of absolute subsidence increases progressively toward the center of current activity on the Island of...
Coastal currents and mass transport of surface sediments over the shelf regions of Monterey Bay, California
Stephen C. Wolf
1970, Marine Geology (8) 321-336
In Monterey Bay, the highest concentrations of medium and fine sands occur nearshore between ten and thirty fathoms. Silt and clay accumulate in greater depths. Contours of median diameter roughly parallel the isobaths.Fine-grained materials are supplied to the bay region from erosion of cliffs which partly surround Monterey Bay, from...

Morphology, sedimentation, and seismic characteristics of an arctic beach, Nome, Alaska - with economic significances
H. Gary Greene
1970, Open-File Report 70-142
Arctic beaches exhibit characteristics that do not occur on beaches in more temperate zones. In the summer of 1967 morphological, sedimentological, and seismic refraction studies were made on an arctic beach near Nome, Alaska, in order to better define these distinguishing characteristics.Several distinct microrelief structures are developed during ice break-up...
