山东五莲七宝山铜及多金属矿床成矿地质特征及找矿方向

Geological Characteristics and Prospecting Direction of Qibaoshan Copper and Polymetallic Mineralization in Wulian County of Shandong Province

摘要:

在对区域成矿地质条件和矿区地质特征认识的基础上，着重研究了七宝山铜及多金属矿床特征，认为矿床的成因属于沿断裂构造充填的中—低温次火山热液矿床。控矿因素主要是断裂构造、岩性、地层，简要分析了该区的找矿标志主要为断裂交汇部位、构造破碎带及其火山岩体等。同时分析了该区的找矿方向，指出了五莲七宝山、南官庄、李家坡3个找矿预测区的潜力，为下一步的找矿工作提供了依据。

Abstract:

Based on the recongnation of regional geological background and geological characteristics, geological characteristics of Qibaoshan copper and polymetallic mineralization are stupied in the paper. It is regarded that the origin of this kind of deposit belongs to medium-low temperature hydrothemal deposit filled along fault structure. Ore-controlling factors are mainly fault structure, lithology and strata. The prospecting signs in this area are mainly composed of the fault interaction part, structural fracture zones and volcanic rock bodies. Meanwhile, ore prospecting direction is analyzed as well. It is pointed out three target areas, they are Qibaoshan predicating mine, Nanguanzhuang predicating mine and Lijiapo predicating mine. It will provide basis for further prospecting in this area.
