Geosphere, February 2008, v. 4, p. 218-246, doi:10.1130/GES00126.1, Figure 13 - A full resolution version of Figure 13. Subset of Plate 3 over the Illipah Au mine in the northern White Pine Range, White Pine County (J, Fig. 6). In the map at top, quartz-bearing units are indicated in magenta, carbonate-bearing units in blue, and jasperoids in orange (Crafford, 2007). Note correspondence of identified quartz with the Illipah mine area, jasperoids, and the Diamond Peak Formation (Mdp). Mj—Joana Limestone. Pc—Pennsylvanian–Permian Riepe Spring and Ely Limestones. Psc—Permian Arcturus Formation (siliciclastics, limestones, and dolomites) and/or Rib Hill Sandstone. Also note identified carbonate within the limestone-bearing units. Image at bottom shows perspective view from Google EarthTM looking southeast over the mine toward the jasperoid, which forms the flat top of the ridge in the background (Nutt and Hofstra, 2003). Cyan arrow in the map at top indicates the look direction of the perspective view. ASTER—Advanced Spaceborne Thermal Emission and Reflection Radiometer. File size is 0.6 MB.
