40Ar/39Ar geochronology of the Tonopah, Divide, and Goldfield districts, Nevada Ar/Ar data are reported from minerals and rocks that were collected as part of a mineral resource investigation of the Tonopah, Divide, and Goldfield districts in Nevada. Data are reported from 92 samples and associated standards from eight separate neutron irradiations in the Denver USGS TRIGA reactor, including separated mineral grains and whole rocks. Data were collected by infrared laser heating of irradiated samples, either incremental heating or fusion, and analysis by multi-collector mass spectrometry. The reported data have been corrected for blanks, radioactive decay, and interfering nucleogenic reactions associated with sample irradiation.

Four mineral separates from the Butte Main Stage vein deposit and two from the Bingham pyrite-enargite vein deposits were also analyzed. Fifteen separates are from hand samples collected from underground mine workings and the remaining 16 are from mine tailings piles and pits excavated within the past 100 years. The separates consist dominantly of pyrite, enargite, and quartz, with lesser amounts of sphalerite, galena, potassium feldspar, bismuthinite, marcasite,...

Much of the data presented here for the Tonopah and Divide districts are for samples collected by Bonham and Garside (1979) during geologic mapping in and around those districts, whereas much of that for samples from the Goldfield district were obtained by Ashley (1974; 1979; 1990). Additional data were derived from samples collected between 2012–2017, as part of the U.S. Geological Survey Mineral Resources Program funded project titled: “Magmatic-tectonic history...

Tellurium (Te)-bearing adularia-sericite epithermal Au-Ag deposits are widely distributed in calc-alkaline magmatic arcs and are an important current and future source of precious and critical metals. However, the source of ore-forming fluids in these deposits remain unclear due to the lack of isotopic evidence on Au-, Ag-, and Te-bearing minerals. To advance understanding of the source of Te and precious...
