Glaciomarine deposits of Miocene through Holocene age in the Yakataga Formation along the Gulf of Alaska margin, Alaska
George Plafker, Warren O. Addicott
1976, Open-File Report 76-84
Perhaps the world's longest and most complete onshore sedimentary record of late Cenozoic glaciation is preserved in the Gulf of Alaska Tertiary province that extends 800 km along the coast of southern Alaska. The Yakataga Formation, with an aggregate outcrop thickness of about 5,000 m, is characterized by variable amounts...
Regional appraisal of the Wilcox Group in Texas for subsurface storage of fluid wastes: Part 1: Geology
Paul Hastings Jones, P. R. Stevens, J. B. Wasselman, R. H. Wallace Jr.
1976, Open-File Report 76-394
Sandy beds of the Wilcox Group in Texas are underlain and overlain by clays of the Midway and Claiborne Groups. The Wilcox is divided by a persistent shale wedge. Contrasting delta systems described as high-constructive and high-destructive exist in the divisions. Merged high constructive deltas characterize the lower, while the...
Stability of highwalls in surface coal mines, western Powder Ridge Basin, Wyoming and Montana
Fitzhugh T. Lee, William K. Smith, William Z. Savage
1976, Open-File Report 76-846
Preliminary results from the first part of a two-part investigation of the stability of highwalls in open-pit coal mines in the Fort Union Formation of the western Powder River Basin of Wyoming and Montana indicate that these highwalls are subject to time-dependent deformation. Field investigations and laboratory physical-properties tests of...
Ground-water resources in the Lompoc area, Santa Barbara County, California
G.A. Miller
1976, Open-File Report 76-183
Water supplies in the Lompoc plain are pumped from highly permeable gravel and sand, which make up the main water-bearing zone. The history of ground-water quality in the Lompoc area shows little change in the Lompoc upland and the Lompoc terrace, but an increase in the concentration of dissolved solids...
Selected field data collected in 1975, northeastern Craig Quadrangle, southeastern Alaska
Henry C. Berg, A. Marianne Fujii
1976, Open-File Report 76-490
This report consists of a computer printout of geologic field data recorded by H.C. Berg from July 2 to July 20, 1975 in the part of the Craig (CR) 1:250,000-scale quadrangle northeast of Clarence Strait (figs. 1 and 2). It contains edited and revised observations on structure, lithology, mineralogy, metamorphism,...
