Denver Microbeam Laboratory: Mineral Resources Research Support
The USGS Denver Microbeam Laboratory provides chemical analysis and characterization of rocks, minerals, and environmental samples in support of a wide variety of USGS projects related to mineral resources, including research projects funded by the USGS Mineral Resources Program. The research applications for these projects range from mineral resource research and assessments, to geologic mapping and geochronology, to geologic hazards and radioactive waste disposal, to the environment and human health.
