关于乌拉根铅锌矿床地质特征及成因分析

Geological characteristics and genesis of the uram lead zinc deposit

新疆乌拉根铅锌矿床的发现是我国近年来有色金属矿地质勘查的重大进展之一。该矿位于塔西南凹陷北部,围岩为下白垩统克孜勒苏群厚层砂砾岩,上部盖层为古新世阿尔塔什组膏盐层,属砂岩容矿的铅锌矿床,矿体受构造控制呈浸染细脉和透镜状分布,与天青石化及黄铁矿化有关。文中在对该矿地质特征进行分析的基础上,探讨其矿床成因,旨在为该矿进一步找矿工作提供参考。

The discovery of the uraen lead zinc deposit in Xinjiang is one of the significant advances in geological exploration of nonferrous metals in recent years. The mine is located in the northern part of the southwest sag of the Tarim Basin. The surrounding rock is the lower Cretaceous kygz thick sand conglomerate, the upper cover is the Paleocene Al Tash group gypsum salt layer, which belongs to the sandstone hosted lead zinc deposit. The ore body is controlled by structural control and is disseminated with fine veins and lens like distribution, which is related to the azitifossilization and pyrite mineralization. Based on the analysis of the geological characteristics of the mine, the genesis of the deposit is discussed, so as to provide references for further prospecting work in the mine.
