Metallogenic Geological Characteristics and Prospecting Forecast of Jinqingding,Sanjia and Yinggezhuang Gold Deposit in Rushan

Jinqingding,Sanjia,Yinggezhuang gold deposit is located in Muping-Wendeng from the southern edge of the text of the eastern part of the Jiaodong,the central of Muping-Rushan metallogenic belt.NNE fracture in this region develops mostly,provides an advantaged occurrence for the enrichment and mineralization of gold hydrothermal.Mu-Ru gold metallogenic belt lays on a side of granite which is on the contact belt of granite in Kunyu mountain and metamorphic rock in Jiaodong group,reflects the ore-controlling characteristics of the time,space and ore-controlling characteristics of rocks.Muping-Rushan metallogenic belt of the region can be divided into four tectonic NW bands,of which only Jinniushan-Jinqingding metallogenic belt,the Sanjia metallogenic belt is relatively strong tectonic metallogenic belt,while the other two with more mineralization weak,non-dyke development,very little industrial mineral deposits.Beginning with metallogenic geological condition,geological characteristics of ore-bed,ore-forming,laws of gold enrichment,we analyse the ore-controlling factors,and put out a new prospecting direction.
