Detection and mapping of mineralized areas in the cortez-uinta belt, utah-nevada using computer-enhanced erts imagery

Content Provider	NASA Technical Reports Server (NTRS)
Author	Goetz, A. F. H. Ashley, R. P.
Copyright Year	1976
Description	The author has identified the following significant results. The reflectance spectra of most hydrothermally altered rocks were characterized by broad ferric iron absorption bands short of 1.1 microns and a sharper hydroxyl band near 2.2 microns; maximum reflectance occurred near 1.6 microns. Their features became more prominent as albedo increased. The MSS color ratio composite images were the most effective and practical means for detecting and mapping limonitic rocks in areas having less than about 50 percent desert brush cover and less than 25-35 percent coniferous tree cover. Limonitic altered and unaltered rocks could not be distinguished in MSS color ratio composite images.
