Study on Geological Characteristics and Prospecting Prospect of Yujiaquan Gold Deposit in Rushan City in Shandong Province

Yujiaquan gold deposit is located in the northeast margin of Jiaolai basin and the west of Mouru metallogenic belt. Development of the strata, structures and magmatic rocks closely related to gold deposits in the mining area and the metallogenic geological conditions are good. In this work, through comprehensive prospecting method of geological, physical and chemical, eight gold mineralization alteration zones have been found in the mining area, and four gold mineralization bodies, one silver mineralization body, one lead mineralization body, four gold deposits and one lead ore body have been delineated. Good prospecting results have been achieved. Based on the analysis of regional metallogenic geological background and geological characteristics of the mining area, geological characteristics of Yujiaquan gold deposit have been introduced in detail, the ore controlling factors and prospecting indicators have been summarized, and prospecting prospects have been studied. It is believed that the potential for gold exploration in this area is great.
