“…Previous studies have assigned all of these moraines to the Tahoe period (Bateman, 1965;Berry, 1991 ). Preservation of these moraines is probably due to the tectonic setting of the piedmont at Bishop Creek.…”

Geology and geochemistry of the West Ore Body and associated skarns, Copper Canyon porphyry copper deposits, Lander County, Nevada, with a section on electron microprobe analyses of andradite and diopside

“…Skarn and tactite have been applied synonymously to contact metamorphosed rock by many authors (Bateman, 1965;Burt, 1972a). Others, however, applied skarn to both regionally and contact metamorphosed rock (Ramberg, 1952).…”

Mineral resources of the Emigrant Basin primitive area, California, with a section on geophysical studies

“…Both of these are located south of Yosemite National Park in mineralized roof pendants comparable in some respects to the roof pendant rocks in the southern part of the Emigrant Basin area. The Pine Creek mine is the leading tungsten producer in the United States, and, according to Bateman (1965), it is located in the largest contact-metamorphic ore deposits in the world.…”

“…Currently productive mines in the Sierra Nevada include the famous Pine Creek and Strawberry tungsten deposits (Bateman, 1965;and Krauskopf, 1953). Both of these are located south of Yosemite National Park in mineralized roof pendants comparable in some respects to the roof pendant rocks in the southern part of the Emigrant Basin area.…”

“…At the time this study was made only one mineral deposit in the primitive area was being prepared for mining; however, prospecting and development of mineral claims, chiefly for tungsten, was being actively pursued. The occurrence of scheelite, sphalerite, molybdenite, and other minerals, which are common in the roof pendant in the southeastern part of the primitive area, are geologically similar to economic deposits elsewhere in the Sierra Nevada (Krauskopf, 1953, andBateman, 1965) and may or may not eventually prove to be of important commercial interest.…”
