FY 15 USGS Mineral Resource Project of Rare Earth Element Deposits in S.E. Missouri

archived

This study proposes to build upon previous work to incorporate drill hole data with modern geologic and geophysical knowledge to produce an improved geologic map of intrusive and extrusive igneous rock lithologies, ores, and alteration zones within Precambrian-age rocks for the study area. Better definition of these factors will aid in characterization of the setting and origin of the known Fe-Cu-Co-Au-REE deposits, and will facilitate identification of potential unknown deposits, providing a basis for mineral resource assessments and new industry exploration in the region. The PI for this project will provide direction on and assistance with sampling and petrophysical measurements of igneous rocks, sedimentary rocks, ores, and alteration zones in aid of delineation of the subsurface geology of the region. Sampling will include drill cores housed at the Missouri Geological Survey (MGS), abandoned mines and outcrop locations. Information on the petrology and petrography of units will also be examined.
