Geophysical and Geochemical Characteristics and Geology of Damoqujia Gold Deposit in Longkou of Shandong Province

Damoqujia gold deposit in Longkou city of Shandong province locates in east part of Yishu fault belt, north part of Zhaoping gold ore-forming belt, and northeast part of Dongfeng gold deposit in Linglong gold field. Major ore-controlling and ore-hosting structures are fault belts with the trend of NE and secondary faults which belong to the host structure. The most favorable parts for gold ore-forming are the zones where two or more fault structures contacted and crossed. Both quartz vein type or altered rock type gold deposits may shows secondary high-resistivity quartz vein or the secondary high-resistivuty silicification belt and sericite-quartz-related belt in the ore-bearing belts. Regional abnormity of these secondary high-resistivty, high-polarization are basic characteristics of vein abnormity in this area. Through analysis on geology, geophysical and geochemical characteristics in this area, ore-prospecting symbol is set up, which will provide basis for further geological exploration.
