Geochemical data for ultramafic rocks and sulfide minerals from the disrupted lower stratigraphy of the Stillwater Complex, USA Geochemical data for ultramafic rocks and sulfide minerals from the disrupted lower stratigraphy of the Stillwater Complex, USA
The layered mafic and ultramafic Stillwater Complex in southwest Montana is known for its platinum-group element (PGE) production from reef-style mineralization (J-M Reef) in the Lower Banded series. Rocks near the base of the complex—the Basal series and Ultramafic series, Peridotite zone—also host elevated concentrations of Ni, Cu, Co, Cr, and PGE. These rocks of the complex’s lower...
Whole rock geochemical data from Arizona porphyry mineral systems (2024) Whole rock geochemical data from Arizona porphyry mineral systems (2024)
This report includes whole rock geochemical data from a newly collected suite of samples from igneous systems across Arizona. The data release includes samples collected in calendar year 2024 that support an ongoing, multi-year project dedicated to characterizing magmatic porphyry systems toward understanding possible basement influence on porphyry style mineralization. This preliminary...
Landslide monitoring site installation details, geotechnical parameters, hydrologic time series data, and landslide locations from storms occurring between 25 December 2022 and 19 January 2023 in the San Francisco Bay area, California. Landslide monitoring site installation details, geotechnical parameters, hydrologic time series data, and landslide locations from storms occurring between 25 December 2022 and 19 January 2023 in the San Francisco Bay area, California.
This data release provides datasets supporting research on landslides triggered by a series of storms in the San Francisco Bay Area, California, that occurred between December 25, 2022, through January 19, 2023. During this period, eight atmospheric river storms delivered intense and prolonged rainfall across the region, leading to significant hydrological responses and widespread...
Geochemical data for volcanic rocks of the northern Mojave Desert Geochemical data for volcanic rocks of the northern Mojave Desert
This release of geochemical data for the northern Mojave Desert is for 330 volcanic rocks sampled over 43 years, with an emphasis on basaltic rocks. It supports a field trip road log in the 2024 Geological Society of America Field Trip Guidebook for the Annual Meeting to be held in Anaheim, CA.
Magnetotelluric data from the Clear Lake Region, Northern California Magnetotelluric data from the Clear Lake Region, Northern California
The Clear Lake Volcanic Field (CLVF) in northern California is a young (2 Ma-0.008 Ma) volcanic system that could be hazardous upon eruption. Magnetotellurics (MT) is a passive electromagnetic geophysical method that measures subsurface electrical resistivity by recording the Earth's electrical response to natural time varying magnetic fields. To further understand the magmatic system of...
Airborne magnetic and radiometric data acquired over parts of Cochise, Graham, Greenlee, Pima, Pinal, and Santa Cruz Counties, Arizona Airborne magnetic and radiometric data acquired over parts of Cochise, Graham, Greenlee, Pima, Pinal, and Santa Cruz Counties, Arizona
This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey of the Arizona Porphyry Copper Belt in southeastern Arizona. The airborne survey was funded by the Earth Mapping Resources Initiative. NV5 Geospatial, in collaboration with EDCON-PRJ, Inc., acquired high-precision airborne magnetic and radiometric data from November 15, 2023...
