Chromium (Cr) is a heavy metal that naturally occurs in the Earth’s crust, and can be found in groundwater in either the trivalent, Cr(III), or in the hexavalent, Cr(VI), form. While Cr(III) is considered an essential trace element for the human body, Cr(VI) is potentially dangerous for human health although the type and intensity of the effect are still being investigated. The widespread use o...

Multispectral remote sensing of hydrothermal alteration in volcanogenic massive sulfide (VMS) ore systems mafic crust is relatively uncommon, part due to the short-wave infrared spectral similarity several key minerals: epidote, chlorite, actinolite, and serpentine. In this study, we developed regional mosaic generation classification workflows for Advanced Spaceborne Thermal Emission Reflectio...
