广西钨矿资源特征、成矿规律与找矿方向
Characteristics, Metallogenic Rules and Prospecting Direction of Tungsten Resources in Guangxi
钨矿作为国家战略性矿产资源,对国家的经济与安全意义重大。广西的钨矿资源在全国占据重要地位,但其成矿规律未得到系统的认识与阐述。对广西钨矿的成矿特征、规律及找矿方向进行深入剖析。结果表明:广西钨矿床按成因类型可分为石英脉型、矽卡岩型和岩体型三大类,其中石英脉型尤为重要。成矿物质来源具有多元性,主要包括富钨岩浆、岩浆热液以及震旦-寒武纪浅变质岩。成矿时代涵盖了加里东、印支、燕山中期和燕山晚期4个时期,其中燕山晚期数量及规模最多。广西钨矿床分布在4个Ⅲ级成矿带的6个重点成矿区:元宝山、越城岭、大明山-昆仑关、珊瑚、玉坡-社垌及油麻坡-松旺,中大型钨矿床主要分布在大明山-昆仑关、珊瑚和油麻坡-松旺成矿区。基于上述成矿规律认识,首次提出酸性至中酸性岩浆岩的影响范围内是钨成矿有利空间,也是有利找矿区段,现有大型石英脉型钨矿深边部、大面积出露燕山期酸性-中酸性岩体与富钙质地层接触带是新一轮钨矿找矿突破的重点地区。
Tungsten ore, a national strategic mineral resource, is crucial to the nation's economy and security. Guangxi's tungsten resources hold a significant position nationwide, yet their metallogenic laws have not been comprehensively understood or elaborated. The metallogenic characteristics, patterns, and exploration directions of Guangxi's tungsten deposits were thoroughly examined. The results show that Guangxi's tungsten deposits can be categorized into three main types based on their genesis: quartz-vein, skarn, and porphyry, with the quartz-vein type being particularly significant. The sources of metallogenic materials are diverse, primarily including tungsten-rich magmas, magmatic hydrothermal fluids, and Sinian-Cambrian shallow-metamorphic rocks. The metallogenic periods span the Caledonian, Indosinian, Middle Yanshanian, and Late Yanshanian, with the latter seeing the highest number and scale of tungsten deposits. Guangxi's tungsten deposits are distributed across six key metallogenic areas within four third-level metallogenic belts: Yuanbaoshan, Yuechengling, Daming Mountain-Kunlun Pass, Hushan, Yupo-Shedong, and Youmapo-Songwang. The medium-to-large tungsten deposits are mainly concentrated in the Daming Mountain-Kunlun Pass, Hushan, and Youmapo-Songwang metallogenic areas. Based on these insights into metallogenic patterns, it is proposed for the first time that the influence range of acidic to intermediate-acidic magmatic rocks is a favorable space for tungsten metallogenesis and a promising exploration area. The deep and marginal parts of existing large quartz-vein tungsten deposits, as well as the contact zones between extensively exposed Yanshanian acidic-intermediate-acidic plutons and calcareous strata, are identified as key regions for the next breakthrough in tungsten exploration.
