安徽贵池安子山铜钼矿床成矿控制因素及矿床成因分析

Analysis of metallogenic control factors and causes of deposits in Anzishan copper-molybdenum deposits in Guichi, Anhui Province

安徽省池州市贵池区安子山铜钼多金属矿床地处扬子准地台下扬子台坳沿江拱断褶皱带。该区域地质构造复杂,矿床类别丰富,铜钼矿床属于高~中温热液交代广义矽卡岩型。为了解该区域的矿床控制因素及成矿原因,对该区域开展研究。研究表明,本区矿床大部分赋存在接触带上或附近,矿石构造主要是浸染状构造与条带状构造,控制本区成矿的构造主要为北西向张扭性裂隙。

The Copper-Molybdenum Polymetallic Deposit of Anzishan In Guichi District, Chizhou City, Anhui Province is located in the arch fold belt along the Yangtze Terrace Pass under the Yangtze Quasi-Terrace. The geological structure of this area is complex, the types of deposits are rich, and the copper-molybdenum deposits belong to the high-to mediumtemperature hydrothermal hydrothermal generalized silica rock type. In order to understand the control factors of the deposits in the area and the causes of mineralization, the area was studied. The results show that most of the mineral deposits in this area are endowed with or near the contact zone, the ore structure is mainly immersion-dyeing structure and strip-like structure, and the structure controlling mineralization in this area is mainly north-west tension-torsional fissure.
