There is increasing demand for mineral mapping applied to identifying and defining deposits and associated hydrothermal systems, delimiting surface expressions of geologic structures that host deposits, and mitigating hazards associated with mineral resource extraction. The Mineral Resources Program has advanced methods of imaging spectroscopy (hyperspectral remote sensing) that are now used routinely by the earth science and remote sensing communities for mineral mapping, soil quality mapping, hazard mitigation, and other terrestrial and planetary applications. The USGS is highly qualified to advance this technology based on its world class expertise in mineral and material spectroscopy and extensive, well-characterized specimen collections (for example, the USGS spectral library). Our laboratories have set standards in the calibration of a wide range of laboratory, field, and imaging spectrometers. This breadth of expertise is critical to accomplishing this objective and provides a comprehensive perspective matched by few research groups.
