摘要
下汪家铜多金属矿床形成于燕山晚期,成矿流体主要来自岩浆期后热液,断裂和岩浆岩是两大重要的成矿条件。控矿构造为北北东向断裂。成矿流体和主要矿质均源于地球深部,以上地幔或壳幔混合带为主,与燕山晚期富碱岩浆活动密切相关。下汪家铜多金属矿床成因上的分析,对该区下一步的找矿工作具有指导意义。
Xiawangjia copper-polymetallic ore deposit formed during late Yanshanian epoch in the northern Wuyi area. The postmagma hydrothermal solution is the principal source of ore-forming fluid. Faults and magmatic rocks are regarded as two important metallogenic factors. The structural control is NNE faults. The ore-forming material and fluid was derived from the depth of the Earth especially from upper mantle or crust-mantle mixing zone ,due to alkali-rich magma activity during late Yanshanian epoch. The special genesis of Xiawangjia copper-polymetallic ore deposit will provide direction for finding ore bodies in the area.
