Magnetotelluric soundings collected in 2019 to help inform depth-dependent fault zone geometry, fluid content and porosity in this part of the fault zone. Data are provided in MTH5 format.

Magnetotelluric stations collected from 2015-2019 across parts of Minnesota, Wisconsin and the Upper Peninsula of Michigan to support regional investigations into the geologic and tectonic framework of the area and to support mineral resource investigations.

Magnetotelluric station data collected from 2016-2019 across parts of Missouri, Arkansas, Tennessee, Illinois, and Kentucky to support regional investigations into the geologic and tectonic framework of the area and mineral resource and geologic hazard investigations.

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

Magnetotelluric sounding data collected in July 2018 in the Silverton Caldera complex, Colorado, in the Southern Rocky Mountain Volcanic Field to understand the geologic structure of this area.
