新疆乌恰县喀什炼铁厂铜铅锌矿床地质特征与成矿潜力探讨

喀什炼铁厂铜铅锌矿床位于苏鲁铁列克隆起区的南部,喀什凹陷的北缘,含矿层位为下白垩统克孜勒苏群五段(K₁kz⁵),赋矿岩性为褪色化含砾砂岩、砂砾岩和砂岩。其所处的岩相古地理位置、地层分布、构造、围岩蚀变等地质特征与区域内乌拉根铅锌矿多有类似,但铜矿化较之突出。本文从区域地质、矿区地质、矿体地质三方面对喀什炼铁厂铜铅锌矿加以介绍,通过成矿条件分析并加以探讨,认为该区具备铜铅锌找矿潜力。对该地区今后开展相关找矿工作具有一定参考意义。

Geological characteristics and ore-forming potential of copper-lead-zinc deposit in Kashi Liantiechang, Wuqia County, Xinjiang

The copper-lead-zinc deposit of Kashi Liantiechang is located in the southern part of the Sulu tielieke uplift and the northern edge of Kashi sag. The ore-bearing horizon is the 5th segment of the lower Cretaceous Kezilesu group(K₁kz⁵). The geological features, such as lithofacies palaeogeographic location, stratigraphic distribution, structure and wall rock alteration, are similar to those of the Wulagen Pb-Zn deposit, but the copper mineralization is better. This paper introduces the copper-lead-zinc deposit in Kashi Liantiechang from three aspects of regional geology, mining area geology and orebody geology. It is of certain reference significance for the prospecting work in this area in the future.
