Zhangjia gold deposit locates in gold mineralization belt in Zhangjia fault belt in Yantai city. This fault locates in east part of Jiaobei faulted uplift with the trend of NNE. It is nearly parallel with Zhaoping fault belt. Large scale pyritization with phyllic belt has been developed in the main section of the lower part. A medium size gold ore body has been found in Zhangjia fault in 1993 by No.8 Geological Team of Shandong Bureau of Geology and Mineral Resources. In the gold exploration in Wangpoding and Chenjiagou areas since 2008, in addition to the main section, nearly parallel tectonic phyllic alteration zone developed in the depth of 300~400m in west part of the main sections. The highest grade of Au is 7.29g/t by reench sampling result, and the highest grade of Au is 22.50g/t by drilling sampling result. According to geological characteristics of Zhangjia gold deposit, and combining with basic geological work in this area, mineralization, occurrence and explorationg direction of Au in Zhangjia fault belt have been introduced briefly.
