Book excerpt: The purpose of this report is to document possible detection capabilities of the LANDSAT multispectral scanner data for use in exploration for uranium rolltype deposits. Spectral reflectivity, mineralogy, iron content, and color parameters were measured for twenty natural surface samples collected from a semiarid region. The relationships of these properties to LANDSAT response-weighed reflectances and to reflectance ratios are discussed. It was found that the single ratio technique of multispectral processing is likely to be sensitive enough to separate hematitic stain, but not limonitic. A combination of the LANDSAT R5,4 and R7,6 ratios, and a processing technique sensitive to vegetative cover is recommended for detecting areas of limonitic stain. Digital level slicing of LANDSAT R5,4 over the Wind River Basin, after geometric correction, resulted in adequate enhancement of Triassic redbeds and lighter red materials, but not for limonitic areas. No recommendations for prospects in the area were made. Information pertaining to technique of evaluating laboratory reflectance spectra for remote sensing applications, ratio processing, and planimetric correction of LANDSAT data is presented qualitatively.
