赣南银坑——青塘矿集区成矿要素分析及深部找矿预测

Analysis of Metallogenic Factors and Deep prospecting prediction in Yinkeng-Qingtang Mineral Concentration Area, Jiangxi Province

赣南银坑-青塘银多金属矿集区位于赣粤闽隆起雩山成矿带之宁都-于都坳陷,东与武夷成矿带相邻,是赣南罕存的重要银金铅锌铜多金属矿集区,深部探测工作发现矿集区深部的钨矿化新线索。本文综合区内勘查及科研的最新成果,从含矿建造、成矿岩体及控矿构造三方面讨论了矿集区内主要矿产成矿控制与资源分布;分析认为矿集区深部找矿潜力巨大,主要包括两大方向:牛形坝矿床深边部和逆冲推覆断裂F1下盘。

The Yinkeng-Qingtang silver polymetallic mineral concentration area located in the Ningdu-Yudu depression along Yushanmetallogenic belt, adjacent to the Wuyimetallogenic belt in the east,is an important Ag-Au-Pb-Zn polymetallic ore field rarely existing in South Jiangxi province, where the work of deep probe discovered new clues of tungsten mineralization in deep. Combining the new prospecting and research achievements, the paper analyzes the controlling and distribution of mineralization in Yinkeng ore field from wall rocks, ore-forming magmatic rocks and ore-controlling structures. The discussions confirm that Yinkeng ore field has a significant prospecting potential in deep, mainly including two directions: the deep or edge of known deposits and the footwall of thrust nappe faults.
