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.

Key words： Bayah dome low sulfur epithermal type Pongkor type hot spring-type gold deposit Indonesia
