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.
