摘　　要：硫铟铜矿(CuInS2)是一种罕见的铟独立矿物,在中国未曾报道过。在研究福建紫金山铜金矿床深部矿石矿物组成时,首次发现了硫铟铜矿。硫铟铜矿通常见于中高温热液矿床,紫金山铜金矿床东南矿段铜矿体中出现了硫钨锡铜矿、硫钼锡铜矿、硫铁锡铜矿、硫砷锡铜矿、锡砷硫钒铜矿、似黄锡矿、辉钼矿等高温矿物,指示紫金山矿床深部成矿温度较高,成矿流体中In、Sn、Pb、Zn、Mo、W含量较高,具有斑岩型等中高温热液成矿系统的找矿潜力。As a rarely observed mineral,roquesite（CuInS2） has not been reported in China yet.During the investigation of the mineral assemblages of the Zijinshan epithermal Cu-Au deposit at the depth,the authors discovered roquesite through electron microprobe analysis.Its chemical composition is Cu1.01In0.91S2.00,resembling the ideal formula Cu1.00In1.00S2.00 of roquesite.As roquesite is usually existent in the mesothermal to hypothermal ore-forming system,the discovery of such hypothermal minerals as kiddcreekite,hemusite,mawsonite,colusite,stannoidite and molybdenite in the deep orebody of southeast Zijinshan Cu-Au deposit suggests that the ore-forming temperature might have been much higher at the depth than estimated before.The authors have also come to the conclusion that the content of In,Sn,Pb,Zn,Mo,W in the ore-forming fluid was high.It can also be inferred that there probably existed a porphyry-like ore-forming system beneath the present high sulfidation-style epithermal Zijinshan Cu-Au deposit.
