Info
Airborne magnetic and radiometric survey of the southeast Mojave Desert, California and Nevada

Digital flight-line aeromagnetic and aeroradiometric survey data over of the southeast Mojave Desert, parts of California and Nevada. Data files are provided in CSV as well as Geosoft binary database and grid exchange format (GXF).

Info
High-Resolution Airborne Radiometric Survey of Mountain Pass, California

Data obtained from a detailed airborne radiometric survey of this area flown by helicopter at a flight-line spacing of 100 and 200 m, a flight-line azimuth of 70 degrees, a nominal flight-line elevation above ground of 70 m, over about 1,814 line-kilometers. Radioelement data are presented for potassium (K), equivalent thorium (eTh), and equivalent uranium (eU). Data are provided in GXF format.

Info
Magnetotelluric data from Mountain Pass, California, 2015

Magnetotelluric (MT) data from 65 stations collected in 2015 in this area create a regional conductivity model near the Mountain Pass mine.

Info

Ar/Ar geochronology of samples from 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 this area. Data are provided in CSV format.

Info
Zircon U-Pb age and trace element data for Cenozoic igneous rocks in the Tonopah area, Nevada

U-Pb ages and concentrations of selected trace elements were analyzed in zircon crystals from nine samples of Cenozoic igneous rocks collected in this area. Data are provided in CSV format.

Info
Fluid Inclusion Noble Gas Data From Goldfield and Tonopah Epithermal Au-Ag Deposits

Helium, neon, and argon isotopic compositions contained in fluid inclusions in 25 samples from these mineral deposits. Four mineral separates from the Butte Main Stage vein deposit and two from the Bingham pyrite-enargite vein deposits were also analyzed. Includes some hand samples from underground mine workings and some from mine tailings piles and pits. Data are provided in CSV format.

Info
