Geosphere, February 2008, v. 4, p. 218-246, doi:10.1130/GES00126.1, Figure 14 - A full resolution version of Figure 14. Subset of Plate 3 over the Easy Junior mining district in White Pine County (E, Fig. 6). Railroad Valley is at lower right. 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 Nighthawk Ridge mine area, jasperoids (br), and the Diamond Peak Formation (included here within the Mcl unit of Crafford, 2007). JP—identified quartz occurrences not included in the geology coverage of Crafford (2007) that are likely to be jasperoids. These quartz bodies mainly occur within the MDcl unit of Crafford (2007) that includes the Pilot Shale, Joana Limestone, and Chainman Shale, and correspond well to mapped jasperoids indicated in red on the map at left, which has been modified from Carden (1991). Dc—Devils Gate Limestone (note correspondence with identified carbonate). ASTER—Advanced Spaceborne Thermal Emission and Reflection Radiometer. File size is 1.9 MB.
