智利中生代铁氧化物铜金型(IOCG)矿床成矿带位于海岸科迪勒拉山带,与斑岩铜金和浅成低温热液型金银矿床共同组成了南美安第斯型活动大陆边缘上成矿系统组合(方维萱,2014)。主要矿床有坎德拉利亚铜矿床(Candelaria:460Mt@0.95%Cu)、曼托贝尔德铜矿床(Manto Verde:600Mt@0.5%Cu;0.1 g/t Au),Santo Domingo铁铜矿床(Sillitoe et al.,2003)。在智利IOCG成矿带上,闪长岩(132~106 Ma)属主要成
The Chilean Mesozoic iron-oxide copper-gold (IOCG) deposit is located in the Cordillera Belt along the coast and forms with the porphyry Cu-Au and epithermal gold-silver deposits the South American Andean-type continental margin Mine System Portfolio (Fang Wei Xuan, 2014). The major deposits are Candelaria (460Mt@0.95% Cu), Manto Verde (600Mt@0.5% Cu; 0.1 g / t Au), Santo Domingo iron-copper deposit ( Sillitoe et al., 2003). At the IOCG metallogenic belt in Chile, diorites (132-106 Ma) are dominant
