中文摘要: 让家溪锑矿位于雪峰山弧形构造带中部拐弯处,是雪峰山弧形隆起锑金钨成矿构造带上典型锑矿床之一,赋矿层位为震旦纪留茶坡组和寒武纪小烟溪组。在系统总结区域成矿地质背景和成矿规律的基础上,通过对矿区矿床地质特征、矿体特征及控矿因素等方面的分析和研究,认为矿体赋存与地层岩性、构造密切相关,北东东—北东向断裂和裂隙控制矿体的富集和成矿;围岩蚀变主要有硅化和黄铁矿化。矿床类型为中低温热液充填型脉状矿床。结合矿区最新的勘查找矿成果,认为矿区边深部有较好的找矿潜力。
Abstract:The Rangjiaxi antimony deposit is located in the middle corner of the Xuefengshan arc structural belt. It is one of the typical antimony deposits in the structure of Xuefengshan arc Sb-Au-W metallogenic belt. The ore bearing strata are Sinian liuchapo formation and Cambrian xiaoyanxi formation. Based on the systematic summary of the regional metallogenic geological background and metallogenic law, through the analysis and study of the geological characteristics, ore body characteristics and ore controlling factors in the mining area, it is considered that the ore bodies are closely related to the lithology,strata and structure,the NEE-NE faults control the enrichment and mineralization of ore bodies.The wall rock alteration mainly includes silicification and pyritization.The type of Rangjiaxi deposit is medium and low temperature hydrothermal filling deposit. Combined with the latest exploration results in Rangjiaxi mining area,it is considered that there is a good prospecting potential in the deep side of the mining area.
