Beginning in Fiscal Year 2017, the project activities are continuing under the Analytical Chemistry project.
Our project addresses the need for specialized facilities and provides technical and scientific support to USGS scientists, academics, and an inquisitive public. Our trained personnel and specialized equipment and laboratories offer expert sample preparation, access to preparation equipment for the do-it-yourselfer, general methods guidance, routine geochemistry, and composition analyses using X-ray diffraction (XRD) and X-ray fluorescence (XRF) instruments. This project also contributes information about the physical properties and the influences of rocks and minerals in the natural and built environments.
We operate several laboratories including Rock Prep (Comminution Lab), Heavy Liquids, X-ray Diffraction, Magnetic Separation, General Chemistry, and Small Instruments. Our laboratories and services provide Central Mineral and Environmental Resources Science Center and Crustal Geophysics and Geochemistry Science Center scientists with the expertise, equipment, and methods needed to deconstruct rocks and enlarge understanding of geologic processes occurring at field, disaster, and prospect sites.
