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).

On February 14, 2019, just before 2:56 am local time (Pacific Standard Time), a landslide initiated from the natural hillslopes above the City of Sausalito, California. The landslide, properly identified as a debris flow, overran a road (Sausalito Boulevard) located immediately below the landslide source area, and impacted and destroyed several residential structures. One person was located in one of the residences and survived the disaster after being transported in their home down the slope. The U.S. Geological Survey responded to this event within hours of the landslide and provided situational awareness of possible secondary landslide hazards associated with the event. The USGS also rapidly mobilized its topographic...
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...
