Middle Tertiary plutonism in the Santa Catalina and Tortolita Mountains, Arizona
S.C. Creasey, Norman G. Banks, R. P. Ashley, Ted G. Theodore
1976, Open-File Report 76-262
Recent reconnaissance geologic mapping in the Santa Catalina and Tortolita Mountains of southeastern Arizona, supplemented by new and published potassium-argon and fission-track ages, suggests that a large middle Tertiary (about 25 m.y.) composite batholith crops out extensively in both mountains. More than two-thirds of the batholith and the contiguous wallrocks...
Measured and simulated ground-water levels in the Franklin area, southeastern Virginia
O. J. Cosner
1976, Water-Resources Investigations Report 76-83
The Lower Cretaceous aquifer is the principal source of water in Southeastern Virginia. Synoptic water-level measurements made since 1970 have been used to verify a digital model of the aquifer. Measurements made in December 1973, August and December 1974 were used to further verify the model, using updated pumpage for...
Teton Dam flood of June 1976, Rose quadrangle, Idaho
John H. Bartells, Larry L. Hubbard
1976, Hydrologic Atlas 578
The failure of the Teton Dam caused extreme flooding along the Teton River, Henrys Fork, and Snake River in southeastern Idaho on June 5-8, 1976. No flooding occurred downstream from American Falls Reservoir. The inundated areas and maximum water-surface elevations are shown in a series of 17 hydrologic atlases. The...
Preliminary investigation of the elemental variation and diagenesis of a tabular uranium deposit, La Sal Mine, San Juan County, Utah
Robert A. Brooks, John A. Campbell
1976, Open-File Report 76-287
Ore in the La Sal mine, San Juan County, Utah, occurs as a typical tabular-type uranium deposit of the-Colorado Plateau. Uranium-vanadium occurs in the Salt Wash Member of the Jurassic Morrison Formation. Chemical and petrographic analyses were used to determine elemental variation and diagenetic aspects across the orebody. Vanadium is...
Submarine faults and slides that disrupt surficial sedimentary units, northern Gulf of Alaska
Paul R. Carlson
1976, Open-File Report 76-294
Faults and submarine slides or slumps of Quaternary age are potential environmental hazards on the outer continental shelf (OCS) of the northern Gulf of Alaska. Most of the faults that approach or reach the seafloor cut strata that may be equivalent to the upper Yakataga Formation (Pliocene-Pleistocene). Along several faults...
