摘　　要：印度尼西亚Cikotok矿区帕瑟埃拉金矿位于巽他-班达岛弧的中部Bayah穹隆中,宏观上具有找到大型矿床的地质前提.成矿围岩为始新世末—中新世早期的安山岩,围岩蚀变强烈,分带性明显,金矿脉具有多条近平行产出特征.矿床有4个成矿阶段:石英-蒙脱石-绿泥石阶段,石英-绢云母-黄铁矿阶段,石英-冰长石-硫化物-含锰矿物阶段,块状石英阶段.矿床成因类型为大洋岛弧型低硫浅成低温热液型,细分类型为“Pongkor型”条带状低硫含金石英锰氧化物矿脉型金矿,其浅表部为热泉型金矿.矿床的深部找矿潜力大,具有大型金矿的成矿潜力.The Pasir Ela gold deposit in the Cikotok orefield of Indonesia,tectonically located in Bayah dome in the middle of Sunda-Banda island arc,has the macroscopic geological precondition for finding large deposits.The ore-forming wall rock is the late Eocene-early Miocene andesite,with strong alteration and obvious zonation,in which several gold veins are occurred nearly parallel to one another.The deposit experienced 4 metallogenic stages,including quartz-smectite-chlorite,quartz-sericite-pyrite,quartz-adularia-sulfide-manganese bearing mineral and massive quartz.The gold deposit is genetically low sulfur epithermal type of oceanic island arc,with the subdivision of Pongkor-type banded low sulfur gold-bearing quartz-manganese oxide vein,and the hot spring type in the superficial part.It is concluded that the deposit has great deep prospecting potential and metallogenic potential of large gold deposits.
