Abstract:Qibaoshan copper gold deposit is located in WulianJiaonan metallogenic belt (Ⅳ) Wulian Qibaoshan copper, gold, leadzinc metallogenic prospecting area (Ⅴ). It is a key exploration area for gold and polymetallic deposits in Shandong province. From 1970s 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 porphyryepithermal gold and polymetallic deposits, the ore bodies are controlled by cryptoexplosive breccia barrels (veins) and the mineralization is vertically zoned. Obviously, the oreforming materials are all from the subvolcanic rocks, and the oreforming 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.
