Mineralogic information from a new airborne thermal infrared multispectral scanner
Kahle AB and Goetz AH. 1983. Mineralogic information from a new airborne thermal infrared multispectral scanner. Science. 222(4619):24-27
This paper describes early results from NASA's airborne Thermal Infrared Multispectral Scanner (TIMS). "The diagnostic information in the multispectral data...lies in the emissivity variations as a function of wavelength." Using data collected in this way, the authors developed a color composite of alluvial fans on the western side of Death Valley, at the foot of the Panamint Mountains, showing specific features which allow distinguishing quartzites, carbonates, volcanic rocks and saline deposits. The method is especially useful for silicates, which are not readily identified by sensors of other wavelengths. Includes a color TIMS image of the alluvial fans and a generalized lithologic map of the same area for comparison. (Also images of the Cuprite mining district in Nevada.)
