Aerial view north toward south side of Quaternary basalt neck and pyroclastic deposits of Yumtheska Vent West sample site, K-Ar age 0.780±0.15 thousand years (ka) (Wenrich and others, 1995).
Aerial view northwest toward basalt dikes (photograph EI06) on west side of Unkar Creek canyon in Solomon Temple Member of Dox Formation, Unkar Group, about 2 miles west of river mile 72.5.
This U.S. Geological Survey (USGS) data release provides whole rock major, minor, and trace element geochemical data from the fluorine-rich Mount Emmons-Redwell porphyry molybdenum (Climax-type) deposit (Mt. Emmons-Redwell deposit), located approximately 5.6 km (3.5 mi) northwest of Crested Butte, Colorado. The Mt. Emmons-Redwell deposit partly underlies Redwell Basin on the northwest flank of Mount Emmons in the west-central region of the Colorado Mineral Belt. Mineralization of the Mt. Emmons-Redwell deposit occurs at depth as vein, veinlet, stockwork, and fracture-hosted Climax-type mineralization [308 Mt at 0.32% Mo (Galey, 1978; Guarnera and Anderson, 2007)], and is associated with the Mt. Emmons igneous complex....
