Relative-gravity surveys were carried out using a ZLS Burris relative-gravity meter. The effect of solid Earth tides and ocean loading were removed from the data. Instrument drift was removed by evaluating gravity change during repeated measurements at one or more base stations. Absolute-gravity surveys were carried out using a Micro-g LaCoste, Inc. A-10 absolute-gravity meter. Vertical gradients between the different measuring heights of the absolute- and relative-gravity meters were measured using a relative-gravity meter and fully-adjustable tripod, and used to correlate the measurements between the two instruments. Relative-gravity differences and absolute-gravity data were combined using a least-squares network...

Surface geophysical surveys were conducted from 2016 to 2018 in the greater East River Watershed near Crested Butte Colorado with a focused effort in Redwell Basin as part of a broader study of the role of bedrock groundwater in the hydrogeology of mineralized mountain watersheds. Five electrical resistivity tomography (ERT) profiles were acquired within Redwell Basin and Brush Creek to map geologic structure at depths up to 40 meters, depending on the subsurface resistivity, using the Advanced Geosciences, Inc. SuperSting R8 resistivity meter. This data release includes the raw and processed resistivity data as well as inverted resistivity models. All are provided as digital data, and data fields for each file...

The U.S. Geological Survey (USGS) collected gravity data in the Wet Mountains, CO from September 2021 to July 2022 to compliment newly collected airborne magnetic data for surface and subsurface geologic mapping. A total of 261 measurements were collected across two Ediacaran-Ordovician alkaline complexes (Gem Park and McClure Mountain) and gabbroic outcrops suspected Ediacaran-Ordovician in age. These data supplement existing public gravity data to aid the subsurface interpretation of mapped and concealed Ediacaran-Ordovician alkaline intrusions related to rare earth element (REE) mineralization.
From late 2017 to early 2018, our team collected gravity, ground magnetic (ATV and hiked traverses) and rock property (density and susceptibility) data in southern Gabbs Valley in west-central Nevada.
