U and sr isotopes in ground water and calcite, yucca mountain, nevada: evidence against upwelling water

Autor: Daniel R. Muhs, Zell E. Peterman, J. S. Stuckless

Publikováno v: Science (New York, N.Y.). 254(5031)

Hydrogenic calcite and opaline silica deposits in fault zones at Yucca Mountain, Nevada, have created considerable public and scientific controversy because of the possible development of a high-level nuclear waste repository at this location. Stront

The chemical and isotopic record of rock-water interaction in the Sherman Granite, Wyoming and Colorado

Autor: J. S. Stuckless, J. N. Rosholt, I. T. Nkomo, R. A. Zielinski, Zell E. Peterman

Publikováno v: Contributions to Mineralogy and Petrology. 78:209-219

Chemical, isotopic, radiographic, and rock-leaching data are combined to describe the effects of rock-water interactions in core samples of petrographically fresh, 1.43 b.y.-old Sherman Granite. The data serve to identify sensitive indicators of inci

Preliminary investigations of U-Th-Pb systematics in uranium-bearing minerals from two granitic rocks from the Granite Mountains, Wyoming

Autor: I. T. Nkomo, J. S. Stuckless

Publikováno v: Economic Geology. 75:289-295

Analyses of mineral separates from granites from the Granite Mountains, Wyoming, suggest that most of the thorium and at least half of the uranium are associated with biotite, epidote, and accessory minerals. Biotite and epidote contain most of the u

Uranium mineralization in response to regional metamorphism at Lilljuthatten, Sweden

Autor: J. S. Stuckless, B. Troeng

Publikováno v: Economic Geology. 79:509-528

Analyses of six mineralized and five nonmineralized whole-rock drill core samples from the uranium deposit at Lilljuthatten yield a lead-lead isochron age of 420 + or - 1 m.y. This age corresponds to the last stage of the Caledonian Orogeny. None of

Geochemistry of the Cenozoic Volcanic Rocks of Ross Island and Vicinity, Antarctica

Autor: N. H. Suhr, S. B. Treves, J. S. Stuckless, Samuel S. Goldich

Publikováno v: The Journal of Geology. 83:415-435

The Cenozoic volcanic rocks of Ross Island and vicinity, Antarctica, are surface flows, tuffs, breccias, and small intrusives. The prominent rock is basanitoid. Alkali-basalt magma reached the surface over an appreciable length of time and was differ

The possible bearing of the granite of the UPH Deep Drill Holes, northern Illinois, on the origin of Mississippi Valley ore deposits

Autor: J. S. Stuckless, B. R. Doe, M. H. Delevaux

Publikováno v: Journal of Geophysical Research: Solid Earth. 88:7335-7345

The Pb-Pb, Th-Pb, and U-Pb systems of whole-rock drill-core samples of the granite of UPH record at least one postcrystallization event. Treatment of the data on a concordia plot indicate the timing of this disturbance was probably 260 ±35 m.y. ago

Uranium-lead isotope systematics in uraniferous alkali-rich granites from the Granite Mountains, Wyoming; implications for uranium source rocks

Autor: J. S. Stuckless, I. T. Nkomo

Publikováno v: Economic Geology. 73:427-441

Evaluation of U-Th-Pb isotopic analyses of whole-rock granite samples from the Granite Mountains, Wyoming, suggests that uranium has been mobilized at least twice since the intrusion of the granite. Whole-rock Th-Pb, whole-rock Rb-Sr, and zircon U-Pb

A tertiary silicic cauldron complex at the northern margin of the basin and range province, central Arizona, U.S.A

Autor: R. V. Fodor, J. S. Stuckless, Michael F. Sheridan

Publikováno v: Bulletin Volcanologique. 34:649-662

The Superior volcanic field occupies approximately 8,000 square kilometers of central Arizona in the zone between the southern Basin and Range Province and the Colorado Plateaus Province. The primary structural elements of an eruptive center in the w
