(1) A TIMS image (5-3-1 decorrelation stretch) and (2) corresponding geologic map showing several important map units.  To the Left are TIMS (red squares) and lab (blue diamonds) spectra for six rock types from localities noted on the geologic map.  The TIMS imagery is partially successful at discriminating the Proterozoic gneiss from the tonalite pluton, with differences seen both in the image and in the spectral data.  The gneiss has a distinctive red-blue striped appearance in the northern portions of this 5-3-1 image, where it consists of a relatively thick sequence of banded amphibolite and quartzo-feldspathic (Q-F) gneiss.  The gabbroic and ultramafic rocks, (C) and (D), are easily differentiated from the surrounding units but not from each other.  Thermal emission spectra for rocks found in the White Tank Mountains.  Red spectra represent spectra derived from the six bands of the TIMS imager.  Blue lines represent spectra derived from a thermal spectrometer that have been deconvolved to TIMS resolution.
