MULTISPECTRAL REMOTE SENSING OF CARBONATE ROCKS IN THE CONFUSION RANGE, UTAH.

Multispectral imagery recorded by the NASA/Bendix 24-channel aircraft scanner over the Confusion Range, Utah, proved to be extremely sensitive to lithologic variations in exposed carbonate rocks. Major carbonate units within a 16-km**2 study area were readily distinguished, and some aspects of their structure and stratigraphy could be inferred from image spectral signatures. Spectral data channels centered at 1. 6 and 2. 2 mu m accounted for much of the data sensitivity to lithologic differences. Rock texture, organic matter content, and weathering expression were important lithologic factors producing spectral variation.
