The Xiongcun porphyry copper-gold ore concentration area, one of the large-size metallogenic areas discovered along the Gangdise porphyry copper belt, occurs in an island arc environment associated with northward intra-oceanic subduction of Neo-Tethys oceanic crust. Through a comparative study of sulfur and lead isotopes of porphyry copper deposits of the island arc environment and those of the collisional orogenic environment in the Gangdise porphyry copper belt, the authors found that they have similar metal sources, but porphyry copper deposits of the island arc environment have experienced weak contamination of crust materials, whereas porphyry copper deposits of the collisional orogenic environment have experienced strong contamination of crust materials.
