湘西狮子山铅锌矿床矿化富集特征及控矿因素——湖南花垣—凤凰地区铅锌矿整装勘查系列研究之一

Mineralization enrichment characteristics and ore-controlling factors of the Shizishan Pb-Zn deposit in western Hunan Province

位于湖南省北西部的湘西花垣狮子山铅锌矿,具有稳定的含矿层位,铅锌矿资源量巨大。铅锌矿的含矿岩层为寒武系下统清虚洞组质纯的含藻屑石灰岩和砂屑石灰岩,岩层单层为厚层至巨厚层,含矿岩层厚度为22.6~237.1m。在含矿岩层中按上、中、下3个部位赋存矿体。在全面总结狮子山铅锌矿床矿化富集特征的基础上,对控矿因素进行了初步分析。

Located in northwestern Hunan Province, the Shizishan Pb-Zn deposit is stratabound and contains huge amounts of Pb and Zn resources. The ores are hosted in the Lower Cambrian Qingxudong Formation, a sequence of algal and clastic limestones, ranging from 22.6m to 237 m in thickness. The ore-hosting rocks are divided into the upper, middle and lower unit. The authors discussed the major factors controlling the mineralization on the basis of analysis of the distribution of ore-bearing rocks and ore enrichment.
