A lead isotope study of mineralization in the Saudi Arabian Shield

Autor: John S. Stacey, Ralph Jackson Roberts, J. W. Gramlich, Maryse H. Delevaux, Bruce R. Doe

Publikováno v: Contributions to Mineralogy and Petrology. 74:175-188

New lead isotope data are presented for some late Precambrian and early Paleozoic vein and massive sulfide deposits in the Arabian Shield. Using the Stacey Kramers (1975) model for lead isotope evolution, isochron model ages range between 720 m.y. an

The plumbotectonics of the West Shasta mining district, eastern Klamath Mountains, California

Autor: John P. Albers, Bruce R. Doe, Maryse H. Delevaux

Publikováno v: Economic Geology. 80:2136-2148

The tectonic setting comprising the West Shasta mining district has often been compared with that of primitive island arcs. Concentrations of uranium, thorium, and lead and lead isotope compositions were determined for Devonian ores and rocks of the

The potential source of lead in the Permian Kupferschiefer bed of Europe and some selected Paleozoic mineral deposits in the Federal Republic of Germany

Autor: Maryse H. Delevaux, K. H. Wedepohl, Bruce R. Doe

Publikováno v: Contributions to Mineralogy and Petrology. 65:273-281

New lead isotopic compositions have been measured for Paleozoic bedded and vein ore deposits of Europe by the high precision thermal emission (triple filament) technique. Eleven samples have been analyzed from the Upper Permian Kupferschiefer bed wit

Lead and strontium isotopic evidence for crustal interaction and compositional zonation in the source regions of Pleistocene basaltic and rhyolitic magmas of the Coso volcanic field, California

Autor: Charles R. Bacon, Ronald W. Kistler, Bruce R. Doe, Hajime Kurasawa, Maryse H. Delevaux

Publikováno v: Contributions to Mineralogy and Petrology. 85:366-375

The isotopic compositions of Pb and Sr in Pleistocene basalt, high-silica rhyolite, and andesitic inclusions in rhyolite of the Coso volcanic field indicate that these rocks were derived from different levels of compositionally zoned magmatic systems

Paragenesis and tectonic significance of base and precious metal occurrences along the San Andreas Fault at Point Delgada, California

Autor: D. H. Sorg, Janet L. Morton, R. J. McLaughlin, Charles Meyer, Maryse H. Delevaux, T. G. Theodore

Publikováno v: Economic Geology. 80:344-359

Studies of sulfide vein mineralization at Point Delgada, California, suggest that the mineralizing process was intimately associated with the San Andreas fault system and/or plate-margin tectonism. The deposits occur along north-south to northeast-so
