Geological Characteristics and Genesis of the ShuiyindongGold Deposit, Guizhou

The Shuiyindong gold deposit is a typical carlin type gold deposit in the contiguous areas of Yunnan-Guizhou-Guangxi provinces. The gold ore-bodies are controlled by fault structures within anticlinal axis, and distributed in an unconformity interface between Longtan Formation (P₃l) and Maokou Formation (P₂m) of Permian Period. The wave-shaped ore-bodies eastwardly plunged in strike direction, and spatially overlapped in vertical direction. It is suggested that the Shuiyindong gold deposit is a carlin type gold deposit which occurred in structural alteration zone of sedimentary carbonate rocks, and is controlled by fault-hydrothermal system. The ore-forming environment is characterized by epithermal, high pressure.
