郧西县水田金矿地质特征及成因

Geological Characteristics and Genesis of Shuitian Gold Deposit in Yunxi County

郧西县拥有丰富的金属矿产资源,矿产分布相对集中。本文通过分析郧西县水田金矿的地质特征,明确矿床成因。研究表明,主要含矿地层为泥盆系铁山组(D_(3)t),主要控矿断裂为北东向断裂,矿石自然类型以碎裂蚀变岩型为主,属中低温热液成因的微细粒浸染型金矿床。

Yunxi County is rich in metal mineral resources with relatively concentrated mineral distribution.By analyzing the geological characteristics of Shuitian Gold Deposit in Yunxi County,the deposit genesis is clarified in this paper.Research has shown that the main ore-bearing strata are the Devonian Tieshan Formation(D_(3)t),with the main ore-controlling fault being a northeast trending fault,and the natural type of ore is mainly cataclastic altered rock type,belonging to a fine-grained disseminated gold deposit of medium to low temperature hydrothermal origin.
