摘　　要：绿山(Cerro Verde)斑岩铜钼矿床位于秘鲁南部古新世—始新世斑岩铜钼成矿带的北端。矿体赋存于前寒武系Charcani片麻岩、晚白垩世Yarabamba花岗闪长岩、古新世英安斑岩和石英电气石角砾岩中,热液蚀变由中心向外分别为:钾化带—泥化带—石英绢云母化带—青磐岩化带。矿床形成与板块俯冲有关的岛弧环境,受区域性印加普丘断裂控制,在古新世英安斑岩侵位,带来了大量成矿热液,形成了世界级的超大型斑岩铜钼矿床—绿山斑岩铜钼矿床。The Cerro Verde porphyry copper molybdenum deposit, located near the northern end of the Paleocene Eocene porphyry copper molybdenum belt of southern Peru. Theore body hosted by Precambrian Charcani gneiss, Late Cretaceous Yarabamba granodiorite, Neocene porphyry and the quartz tourmalite breccia, and the hydrothermal alteration is outward from the center are:potassic- argillic- phyllic and propylitic. The deposit formed in plate subduction and is associated with Incapucio fault. The dacite porphyry emplacement in Paleocene and brought out a large amount of mineralizing hydrothermal, as result a world-class super large porphyry Cu-Mo deposit-Cerro Verde is formed.
