Geosphere, February 2008, v. 4, p. 218-246, doi:10.1130/GES00126.1, Figure 15 - A full resolution version of Figure 15. Subset of quartz and carbonate index maps over Kinsley mining district, Kinsley Mountains, Elko County (C, Fig. 6). Maps are overlain on background of Landsat Thematic Mapper data. Antelope Valley is at right. Map at left is from Lapointe et al. (1991). Note identification of quartz corresponding to both mined and undisturbed jasperoids, and heap leach pile. Patchy jasperoids in upper right of geologic map were too small to be identified using the ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) data. The Tertiary intrusion responsible for the distal-disseminated mineralization in the district is located at the south edge of the maps, near the Phalen mine. Abundant carbonate was identified within limestones of the Ordovician Pogonip Group (Op) that underlie most of the range to the north of Au deposits, and within limestones and dolomites of the Cambrian Windfall Formation to the south.
