GENESIS AND METALLOGENIC POTENTIAL OF THE PASIR ELA GOLD DEPOSIT IN CIKOTOK OREFIELD, INDONESIA
-
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.
Abstract: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.
