贵州省水银洞金矿地质特征及成因浅析

    Geological Characteristics and Genesis of the ShuiyindongGold Deposit, Guizhou

    • 摘要: 水银洞金矿是滇黔桂“金三角”卡林型金矿的重要代表,金矿体赋存于二叠系龙潭组与茅口组不整合界面间,受背斜轴部断裂构造控制,走向上具波状起伏向东倾伏、空间上具多个矿体上下重叠的特点。该矿床属产于沉积碳酸盐岩和构造蚀变体中的“卡林型”金矿,为构造-热液成矿,同时具有中—低温超高压成矿特点。

       

      Abstract: 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.
