山东七宝山铜金矿与福建紫金山铜金矿对比研究
|
摘要
七宝山铜金矿位于五莲-胶南成矿带(Ⅳ)五莲七宝山铜、金、铅锌成矿远景区(Ⅴ)内,该区域是山东省金及多金属矿重点勘查区,20世纪70年代至2008年,相继发现了七宝山铜金矿、钓鱼台硫铁矿和七宝山多金属矿,成矿潜力巨大。2008年至今,该区域虽然开展了大量矿产勘查工作,但收获甚微,外围找矿效果不佳。通过对比研究山东七宝山铜金矿与福建紫金山铜金矿区域成矿背景、矿床地质特征、矿床地球化学特征发现:2个矿床都处于受深大断裂控制的陆相火山盆地中,矿床类型为斑岩—浅成中低温热液型金及多金属矿,矿体受隐爆角砾岩筒(脉)控制,矿化垂直分带明显,成矿物质均来自于潜火山岩,成矿流体以岩浆水为主,含少量大气降水;相对紫金山铜金矿,七宝山铜金矿剥蚀较浅,垂直分带更为复杂,深部缺少斑岩型铜钼矿床。结合紫金山矿集区的勘查实践,认为七宝山潜火山岩体深部和外围潜火山岩与青山群角砾熔岩的接触面是寻找斑岩型铜金矿的有利区域。
Qibaoshan copper gold deposit is located in Wulian-Jiaonan metallogenic belt(Ⅳ) Wulian Qibaoshan copper, gold, lead-zinc metallogenic prospecting area(Ⅴ). It is a key exploration area for gold and polymetallic deposits in Shandong province. From 1970 s in the twentieth century to 2008, Qibaoshan copper gold deposit, Diaoyutai pyrite and Qibaoshan polymetallic deposit have been found successively in this area with great metallogenic potential. From 2008 to now, although a lot of mineral exploration work has been carried out in this region, little has been achieved and the effect of prospecting in the periphery is not good. Through comparative study of regional metallogenic background, geological characteristics and geochemical characteristics of Qibaoshan copper gold deposit in Shandong province and Zijinshan copper gold deposit in Fujian Province, it is found that both deposits are located in continental volcanic basins controlled by deep and large faults. The deposit types are porphyry-epithermal gold and polymetallic deposits, the ore bodies are controlled by cryptoexplosive breccia barrels(veins) and the mineralization is vertically zoned. Obviously, the ore-forming materials are all from the subvolcanic rocks, and the ore-forming fluids are mainly magmatic water with a small amount of atmospheric precipitation. Comparing with Zijinshan copper gold deposit, Qibaoshan copper gold deposit has shallow denudation, more complex vertical zoning and lack of porphyry copper molybdenum deposit in the deep part. Combining with the exploration practice in Zijinshan ore concentration area, it is considered that the contact surface between deep and peripheral Qibaoshan buried volcanic rock mass and breccia lava of Qingshan group is a favorable area for prospecting porphyry copper gold deposits.
