Spectroscopy and Hyperspectral Imaging of Critical Mineral Resources

Our project will characterize the primary critical minerals (minerals that contain critical elements in their base structure) that are not yet in the USGS Spectral Library. We propose to increase understanding of the spectral indicators of critical minerals using lab-based studies of hand specimens and drill core, hyperspectral field scanning, and hyperspectral images collected from aircraft.

Magnetotelluric data from Minnesota, Wisconsin, and Upper Michigan, 2015-2019

This dataset consists of 176 wideband magnetotelluric (MT) stations collected from 2015-2019 across parts of Minnesota, Wisconsin and the Upper Peninsula of Michigan. The U.S. Geological Survey (USGS) acquired these data as part of regional investigations into the geologic and tectonic framework of the area and to support mineral resource investigations. These data have been used to generate a 3D

Magnetotelluric sounding data in the Silverton Caldera complex, Colorado, 2018

This data release includes magnetotelluric (MT) sounding data collected in July 2018 in the Silverton Caldera complex, Colorado, in the Southern Rocky Mountain Volcanic Field, by the U.S. Geological Survey (USGS). Along with geologic mapping, airborne magnetics, airborne electromagnetics, and audiomagnetotellurics, the USGS collected MT data at 22 sites along four profiles ranging from 3 to 6 kilo

Ground-based time-domain electromagnetic data and resistivity models near Manistee National Forest, Michigan, 2020

Ground-based transient electromagnetic (TEM) data were acquired by the U.S. Geological Survey (USGS) in selected locations near Manistee National Forest, Michigan, to define the resistivity structure of the subsurface. Data were acquired using the ABEM WalkTEM system (Guideline Geo Ab, Sundbyberg, Sweden). TEM data were processed and numerically inverted to derive one-dimensional resistivity stru

Success Dam Spillway seismic refraction survey, Porterville, California, December 2018 and July 2019

Compressional- (P-) wave seismic refraction data were acquired in December 2018 and July 2019 along fourteen profiles within the spillway of Success Dam in Porterville, California. A new concrete ogee weir is planned for construction within the existing spillway, and the P-wave seismic velocity models will be used to inform further geotechnical investigations, including siting new geologic borings
