Genesis and Metallogenic Model of the Wulonggou Gold Deposit in Qinghai Province

The Wulonggou gold deposit is the most potential deposit for prospecting in Eastern Kunlun metallogenic belt of Qinghai Province. The analysis and study on the genesisand metallogenic modelof the Wulonggou gold deposit have some important guidance and reference for defining the mineralization type and carrying out the further ore-prospecting work. After collecting the geological data of the Wulonggou gold deposit, such as ore-forming tectonic background, regional strata, lithological characters, geological structureand igneous rocks, the geological characteristics of typical gold-polymetallic deposits (Hongqigou-Shenshuitan, Baidungou and Yanjingou deposits) in this area have been described respectively.And then, the ore-controlling factors and ore deposit genesis of these deposits have been analyzed systemically from the aspects of strata, magmatic rocks and structure. The results show that the Wulonggou gold deposit has experienced a long and many times of metallogenic stage. The complex tectonic evolution causes the formation of Wulonggou gold deposit, which has a close relationship with strata, magmatic rocks and tectonic. On the basis of analyzing the ore-controlling factors and ore deposit genesis, the metallogenic model of the Wulonggou gold deposit has been established, and the relevance geological factors for mineralization have been revealed, which intuitively reflect the change and development process of the Wulonggou gold deposit with multiple sources, polygenetic and multi-stage mineralization.
