Geosphere, February 2008, v. 4, p. 218-246, doi:10.1130/GES00126.1, Plate 2 - Map of study area showing quartz and carbonate index maps overlain on background of 1:500,000-scale geology and faults from Ludington et al. (2005) and a shaded-relief digital elevation model (DEM) having 90 m spatial resolution. U.S. Geological Survey DTED-1 3-arc second DEM data were used to create the shaded-relief image (Reheis, 1999). Detected quartz is shown red, carbonate minerals in green. The geology polygons are partially transparent so that topography from the elevation model is visible. The explanation at right indicates the primary lithologies from the vector geology coverage. Secondary lithologies are also shown, in parentheses. Main roads are shown in white. File size is 45.4 MB.
