滇东南小洞锑矿床地质特征与成因探讨

Discussion on Geological Characteristics and Genesis of the Xiaodong Antimony Deposit in Southeastern Yunnan

通过野外地质调查,系统分析了滇东南小洞锑矿床的成矿地质背景和成矿地质特征,分析研究了矿床的控矿因素,探讨了矿床成因。认为小洞锑矿床为热水沉积-改造型矿床,控矿因素主要为寒武系中统田蓬组下段硅质岩含矿层位和控矿构造。

Through field geological surveys,the mineralization geological background and characteristics of the Xiaodong antimony deposit in southeastern Yunnan were systematically analyzed,and the ore-controlling factors of the deposit were analyzed and studied,and the genesis of the deposit was explored.It is believed that the Xiaodong antimony deposit is a hydrothermal sedimentary reformed type deposit,and the ore-controlling factors are mainly the siliceous rock ore-bearing layers and ore-controlling structures in the lower section of the Tianpeng Formation in the Middle Cambrian.
