Geological Characteristic and Origin Analysis for Walegen Gold Deposit in Zeku County, Qinghai, China
-
Abstract
The Walegengold deposit is located in western Qinling Mountains, is the only one large gold deposit found in Western Qinling metallogenic belt in Qinghai Province. By analyzing the geological background, deposits(body) characteristics, rock(ore) chemical composition and its content of Walegen deposit, the results show that the ore bodies was mainly produced in sedimentary rocks(composed byclastic and carbonate rocks)and intermediate-acid intrusive rocksof Early and Middle Triassic Shilongwuhe Formation.The ores are formed by gold-bearing mineral, which were disseminated in the ore-bearing rocks, located and limited within the fracture zone. The formation of gold deposit is the integrated product of tectonic movement, magmatism and sedimentation, which is controlled by ore-forming material source, metallogenic environment and mineralization. Regionally, this deposit is connected with the Hezuo and Xiahe gold mineralized belts in Gansu Province, having the same mineralization background with Zaozigou, Zaishang, Daqiao, Yangshan gold deposits, as well as the Dashui and Zhongqu gold deposits in the Maqu-Nanping gold mineralized sub-zone. All of these gold deposits have similar genetical characters, belonging to the micro-grained disseminated gold deposit. -
