A high-resolution airborne magnetic and radiometric survey of the southeast Mojave Desert, parts of California and Nevada was flown by EDCON-PRJ, Inc. from December 13, 2019 to March 21, 2020. The high-resolution fixed-wing survey was flown at a flightline spacing of 200 m, an azimuth of 70 degrees, a nominal elevation above ground of 100 m, and consists of about 17,277 line-kilometers. Tie lines were flown at a flightline spacing of 2 km with an azimuth of 160 degrees. Magnetic data were processed by EDCON-PRJ, Inc. and include corrections for diurnal variations of the Earth's magnetic field, magnetic field of the aircraft, tie-line leveled, micro-leveled, and an International Geomagnetic Reference of the Earth for the time of the survey. Radiometric data were processed by the contractor and include corrections for aircraft and cosmic background radiation, radon background, Compton scattering effects, and variations in altitude. Data presented include a readme file; survey report; magnetic and radiometric databases; and grids of residual magnetic intensity, potassium, equivalent thorium, and equivalent uranium.

Rare Earth Element Deposits in the Southeast Mojave Desert
In an effort to better understand domestic resource potential, the USGS is investigating the genetic relationship between rare earth element deposits at Mountain Pass, California and Music Valley (Pinto Mountains, California) and extend these studies across a 130-km long belt of alkaline Proterozoic rocks in the southeast Mojave Desert. Such a combined study would significantly improve our... - Connect
