Products of the emissivity-temperature separation of the TIMS data. Band 3 (9.2 micron)
emissivity image with darker areas indicating emissivity lows or strong absorptions. The
areas of active sand show the largest absorption indicating the presence of quartz and
feldspar. In contrast, dolomite in the Providence Mountains and the large amount of magnetite
and clay in the washes have the weakest spectral features and appear brightest [Ramsey, et al., 1999].
