【摘要】：广西龙圩区泥冲矿区位于钦杭成矿带大瑶山多金属矿集区,区域性博白—梧州深断裂和苍梧—大黎隐伏基底断裂交汇处,近期钨多金属矿勘查取得新的突破。本文从区域成矿地质背景、矿区围岩岩性组合特征、构造断裂的控岩及控矿特点、燕山早期泥冲花岗斑岩体的地球化学特征及其侵入与成矿的专属性、矿体产出及分布规律等矿床地质特方面进行总结,认为泥冲岩体是成物质及成矿热液的主要来源,岩体接触带是成矿有利部位,成分比较复杂的夕卡岩更有利于钨金铜矿富集,矿区外围仍有提升资源量的空间和潜力。该研究对大瑶山地区钨多金属矿的找矿工作具有一定的指导意义。
[Abstract]:Nichong mining area in Longwei area of Guangxi is located in the Polymetallic concentration area of Dayaoshan in the Qinghang metallogenic belt, where the deep fault of Bobai-Wuzhou and Cangwu-Dali concealed basement fault intersects. Recently, new breakthroughs have been made in the exploration of tungsten polymetallic deposits. In this paper, the regional metallogenic geological background, the lithologic assemblage characteristics of the surrounding rock of the ore area, the controlling rock and ore-controlling characteristics of the tectonic faults, the geochemical characteristics of the early Yanshanian mud-chong granitic porphyry and their intrusive and metallogenic specificity are discussed. The geological characteristics of ore bodies, such as the occurrence and distribution of ore bodies, are summarized. It is concluded that the mud-chong rock mass is the main source of ore-forming material and ore-forming hydrothermal fluid, the contact zone of the rock mass is the favorable metallogenic position, and the skarn with more complicated composition is more favorable for the enrichment of tungsten, gold and copper deposits. There is still space and potential to increase the amount of resources in the periphery of the mining area. This study has certain guiding significance for the prospecting of tungsten polymetallic ore in Dayaoshan area.
