Post-collisional Sb and Au mineralization related to the South Tibetan detachment system, Himalayan orogen

More than 50 Sb–Au deposits and occurrences have recently been found in an E–W-striking structural–thermal dome zone, related to the South Tibetan detachment system (STDS) in the Himalayan orogen. They are mainly distributed around the thermal domes intruded by mid-Miocene leucogranite bodies, and show a metallic zoning varying from Au, Sb–Au, to Sb mineralization from the domes outwards. At least three mineralization styles are recognized,...
