望峰金矿床位于中天山北缘冰达坂韧性剪切带内,成矿单元划分属于博罗科努多金属成矿带内天格尔-可可乃克次级成矿带,矿体主要赋存于糜棱岩化花岗岩中,主要矿石类型为石英脉型和蚀变糜棱岩型矿石。对两种类型矿石中的绢云母进行~(40)Ar/~(39)Ar测年,获得坪年龄分别为(250.9±3.0)Ma、(255.8±3.0)Ma,两个样品正反等时线年龄与坪年龄在误差范围内一致,表明坪年龄结果可信,可以代表成矿年龄,说明望峰金矿床的主成矿期时代为晚二叠世末期,且蚀变糜棱岩型矿石的形成时代比石英脉型矿石略早。结合矿区地质情况及前人的研究结果,认为望峰金矿床是剪切带型金矿床,冰达坂韧性剪切带控制了望峰金矿的成矿过程。
The Wangfeng gold deposit is located in the Bingdaban ductile shear zone on the northern margin of the Middle Tianshan Mountains. The metallogenic unit belongs to the Tiangeer-Kekeishi secondary metallogenic belt within the Boronkonu polymetallic metallogenic belt. The main orebody Preserved in mylonitized granite, the main ore types are quartz vein type and altered mylonite type ore. The dating of ~ (40) Ar / ~ (39) Ar in sericite from two types of ores was obtained. The average ages of the samples were (250.9 ± 3.0) Ma and (255.8 ± 3.0) Ma, Line age and Ping age are consistent within the error range, indicating that Ping age is credible and can represent the age of mineralization, indicating that the main mineralization period of Wangfeng gold deposit is late Late Permian, and that the mylonite-type ore is altered The formation of a slightly older quartz vein type ore. According to the geological conditions in the mining area and the results of previous studies, it is considered that the Wangfeng gold deposit is a shear zone type gold deposit and the Bingdaban ductile shear zone controls the mineralization process of the Wangfeng gold deposit.
