Ag-Cu-Pb-Bi Sulfosalts axã àÉ Darwin, Inyo County, California

INTRODUCTION The Darwin mining district, Inyo County, California, located at 36o 17’ N., 117o 35’ W., has long been known for its deposits of lead-silver-zinc ore, including several rare sulfosalts; in addition, ores of tungsten, antimony, copper and gold have been produced. Complete descriptions of the Darwin Quadrangle geology and ore-related deposits are given by Hall and MacKevett (1958), Czamanske and Hall (1975), Hall (1962,1971), and Hall et al. (1971).
