Abstract:In order to strengthen deep ore prospecting in Zhaoping fault belt, new prospecting ideas have been summarized as follows: the ore bearing depth and ore body scale of three main faults in northwestern Jiaodong Peninsula are symmetrical, which has been verified in Shuiwangzhuang mining area of Zhaoping fault belt . By the guidance of the profile which cross 4 rights of prospecting at the depth of more than 5000m, the depth of prospecting work extends from 1500M to 2200m, newly increased gold resources are 170t, and total amount of submitted gold resources of Zhaoping fault belt are 1080t. The newly increased gold resource of No.2 ore body is nearly 90t, the amount of gold resource has increased to more than 120t, and single ore body can reach super large scale. According to the research, it is found that thousand meters scale thickness alteration zone has been formed by the superposition of No.208 fault in Jiuqujiangjia and Potouqing fault in northern Zhaoping fault belt. According to alteration degree, it can be divided into five floors from shallow to deep part,The first and second floor is controlled by Potouqing fault, the third floor is controlled by Potouqing fault and Jiuqufault, and the fouth and fifth floor is controlled by Jiuqu fault. The thick ore body occurres in the phyllic granitic cataclasite of the fouthfloor alteration zone.The application of new ideas and new methods has greatly improved the rationality of arrangement which has brought about great achievements that the rate for ore discovery of drill holes reache 100%. The deep trajectory of Zhaoping fault belt is presented which shows that No. 208 fault in Jiuqujiangjia is the major deep prospecting target in northen Zhaoping fault belt.
