·elements of economic value particularly the rare earth elements REE A variety of REE are vital to the defense aviation medical and electronics industries and are emerging as some of the most high demand metals for Mafic Alkaline Magmatism and Rare Earth Element Mineralization in the Mojave Desert California The Bobcat Hills
·Occurrences of alkaline and carbonatite rocks with high concentrations of rare earth elements REE are a defining feature of Precambrian geology in the Mojave Desert of southeastern California The most economically important occurrence is the carbonatite stock at Mountain Pass which constitutes the largest REE deposit in the United States
·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
