广西珊瑚钨锡矿地质特征及控矿因素
Geological Characteristics and Ore-Controlling Factors of the Shanhu Tungsten-Tin Deposit, Guangxi
摘要: 珊瑚钨锡矿位于广西东北部富贺钟矿集区，是南岭钨锡成矿带上典型的大型热液石英脉型矿床，具有重要的经济价值与成矿研究意义。文章在系统收集与整理矿区地质资料的基础上，通过野外调查与室内综合分析，重点阐述了珊瑚钨锡矿床的地质特征、控矿因素与找矿标志。研究结果表明，矿体主要赋存于泥盆系中–下统碎屑岩–碳酸盐岩建造中，受北东向断裂构造控制显著，与燕山期花岗岩岩浆活动密切相关。矿床成因属于岩浆热液充填–交代型，成矿过程具有多阶段演化特征。文章总结了地层、构造、岩浆岩等多重控矿因素，并归纳了包括地层岩性、构造部位、蚀变类型、地球化学异常及矿物组合在内的综合找矿标志，旨在为该区深部及外围钨锡矿产资源勘查提供科学依据。
Abstract: The Shanhu tungsten-tin deposit, located in the Fu-He-Zhong ore cluster in northeastern Guangxi, is a typical large-scale hydrothermal quartz-vein type deposit along the Nanling tungsten tin metallogenic belt, holding significant economic value and metallogenic research importance. Based on systematic collection and review of geological data from the mining area, and through field investigation and integrated laboratory analysis, this study focuses on elucidating the geological characteristics, ore-controlling factors, and prospecting indicators of the Shanhu tungsten tin deposit. The results indicate that the ore bodies are primarily hosted in the Middle Lower Devonian clastic carbonate rock formation, dominantly controlled by NE trending fault structures, and closely associated with Yanshanian granitic magmatic activity. The deposit genesis is classified as magmatic hydrothermal filling replacement type, with a multi stage evolutionary mineralization process. This paper summarizes the multiple ore controlling factors, including stratigraphy, structure, and magmatic rocks, and synthesizes comprehensive prospecting indicators encompassing lithology, structural setting, alteration types, geochemical anomalies, and mineral assemblages. The aim is to provide a scientific basis for further exploration of tungsten tin resources in the deep and peripheral areas of this region.
