摘要:
横路矿区位于朱溪矿集区内,其成矿条件与世界最大钨矿床——朱溪矿床类似,目前已发现了多处找矿线索,但前期工作主要聚焦于500 m以浅,亟待探索该区深部找矿前景。本文从矿区地质、地球物理、地球化学、遥感特征及钻探验证等方面综合分析,并与朱溪矿区进行对比,发现二者在成矿地层层位、控岩控矿构造以及岩浆岩所处成岩-成矿事件等重要成矿条件上极为相似。此外,横路矿区的浅表矿化蚀变分布情况与岩脉密切相关,物化探异常及岩脉分布特征显示深部存在隐伏岩体。综合分析认为横路矿区深部找矿潜力巨大,具有找寻破碎带(热液脉)型、矽卡岩型及斑岩型铜钼金多金属矿床的良好前景。

Abstract:
The Henglu mining area is located in the Zhuxi ore concentration area, and its metallogenic conditions are similar to those of the Zhuxi ore deposit, the world's largest tungsten deposit. Many prospecting clues have been found in the 500 m in shallow so far, and it is urgent to explore the deep ore-searching prospect in this area. Comprehensive analysis from geological, geophysical, geochemical, remote sensing characteristics and drilling verification, we found that the metallogenic conditions, such as oreforming strata, rock and ore controlling structures and diagene-metallogenic events in magmatic rocks, are very similar to those in Zhuxi mining area. In addition, the distribution of superficial mineralization alteration in Henglu mining area is closely related to the dike, the physicochemical anomaly and dike distribution in Henglu mining area indicate the existence of concealed magmatic body. Based on this, the authors consider that the Henglu area has the potential to find structural fracture zone (hydrothermal vein), skarn and porphyry copper-molybdenum -gold polymetallic deposits.
