Episodic Ore Redistribution in Carlin-Type Gold Deposits in Southeastern Yunnan Province, SW China
Abstract
Abstract The central-southern Youjiang basin in southeastern Yunnan hosts numerous Carlin-type gold deposits, such as the pyroclastic-hosted Bieli and the siliciclastic-hosted Bielidong deposits. In both deposits, gold occurs as lattice-bound Au+ in sulfide minerals of different paragenetic stages: sedimentary framboidal pyrite (PyS), diagenetic dissolution-reprecipitation porous pyrite (PyDR), hydrothermal early ore pyrite (Py1), main ore pyrite/arsenopyrite (Py2/Apy2), and late ore pyrite (Py3). The textures show there were multiple pulses of fluid flow related to the formation of the deposits. Sedimentary and diagenetic pyrite has negligible Au (
