Plate 1. Map of study area showing vectorized quartz and carbonate index maps, overlain on Landsat Thematic Mapper derived from U.S. Geological Survey Seamless Data Distribution system, relative to hot springs (black Xs), significant ore deposits (colored symbols), and major roads (gray lines). Quartz detected using the ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) TIR (thermal infrared) data is shown with red polygons, and detected carbonate minerals with green polygons. The mineral index maps were simplified prior to vectorization using a 3 x 3 majority filter. Unfiltered maps are shown in raster format in Plates 2 and 3, and in other figures. The Landsat image is a color composite of bands 2, 3, and 4 displayed in red, green, and blue, respectively. In this treatment, green vegetation is displayed in hues of blue. Hot spring locations are from Shevenell and Garside (2005). The ore deposit symbols indicate deposit type, whereas the color indicates the primary commodity (see legend). Displayed ore deposit locations were selected from the Mineral Resources Data System (2007), an international database of mineral site records with related geologic, commodity, and deposit information. The deposits shown are the economically significant Au, Ag, Cu, Pb and Zn deposits as defined by Long et al. (2000), or listed in Wallace et al. (2004), as well as the largest known examples of the Fe, Mn, Mo, W, Sn, Be, F, Sb, Hg, and barite deposits (Lowe, 1985; Sherlock et al., 1996).
