A detailed aeromagnetic survey of Mountain Pass, California was flown by CGG Canada Services Ltd. (CGG) during November and December, 2016. The high-resolution helicopter survey was flown at a flightline spacing of 100 and 200 m, a flightline azimuthal direction of 70 degrees, a nominal flightline elevation above ground of 70 m, and consists of about 1,814 line-kilometers. Tie lines were spaced at a 1-km interval with a flight-line azimuthal direction of 160 degrees. A Scintrex CS-3 cesium magnetometer was used throughout the airborne survey as well as for the ground base station survey. Data are presented as residual magnetic intensity (RMI) in nanoteslas (nT).

A detailed airborne radiometric survey of Mountain Pass, California was flown by CGG Canada Services Ltd. (CGG). The high-resolution helicopter survey was flown 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, and consists of about 1,814 line-kilometers. Tie lines were spaced at a 1-km interval with a flight-line azimuth of 160 degrees. Data were collected using a Radiation Solutions RS-500 spectrometer and processed by CGG using standard radiometric surveying techniques (e.g., International Atomic Energy Agency, 2003) that include corrections for aircraft and cosmic background radiation, radon background, Compton scattering effects,...

The Trans-Pecos region of West Texas and Southern New Mexico contains a series of rare earth element (REE) enriched ~ 34-36 Ma intrusive rhyolites and syenites. One such intrusive in the Sierra Blanca Mountains, Texas, hosts the Round Top REE deposit which is one of the few REE deposits in the U.S. with an economic evaluation and is scheduled to go into production in 2025. In addition, Alkaline igneous rocks in the Cornudas and Hueco Mountains, both within the Trans-Pecos area, also show high concentration of REEs and other critical elements. In early 2021 an aeromagnetic and aeroradiometric survey was flown over the Trans-Pecos region with the following objectives: 1) Detect regional trends, fractures, or patterns...

Images of subsurface electrical conductivity are useful for locating fluids and other electrically conductive phases at depth in the Earth. This data release presents electrical conductance maps estimated from a 3D model of the Great Basin, USA, at five different depth ranges, spanning 2 to 200 km depth. Electrical conductance is the integration of electrical conductivity in a depth range. Great Basin electrical conductivity is estimated through 3D inverse modeling of over 800 publicly available magnetotelluric (MT) transfer functions. The transfer functions can be found on the electromagnetic transfer function repository hosted by the Incorporated Research Institutions of Seismology (IRIS) data management center...
