摘要
针对贵州猪拱塘超大型铅锌隐伏矿床的发现过程、地质背景、控矿构造及勘查技术方法。猪拱塘矿床位于贵州省赫章县,受控于紫云-垭都逆冲滑脱构造系统,是中二叠统栖霞组碳酸盐岩中发现的隐伏MVT型铅锌矿床。通过地质填图、构造解析、物探方法及钻探技术的综合应用,历时多年勘查,最终实现找矿重大突破。通过分析矿突破的关键因素,包括地质背景、控矿构造、勘查技术创新与“产学研”紧密结合的科研勘查模式,并提出进一步优化勘查技术方法的策略,为黔西北地区乃至全国的隐伏矿找矿工作提供了宝贵经验和启示。
The discovery process,geological setting,ore-controlling structure and exploration techniques of the superlarge concealed lead and zinc deposit in Zhugangtang,Guizhou Province were studied.Located in Hezhang County,Guizhou Province and controlled by Ziyun-Yadu thrust slip tectonic system,Zhougongtang deposit is a buried MVT type lead zinc deposit found in carbonate rocks of the Middle Permian Qixia Formation.Through the comprehensive application of geological mapping,structural analysis,geophysical exploration method and drilling technology,the exploration lasted for many years,and finally achieved a major breakthrough in prospecting.By analyzing the key factors of mineral breakthrough,including geological background,ore-controlling structure,exploration technology innovation and scientific research exploration mode closely combined with"production,university and research",the strategy of further optimization of exploration technology and methods is proposed,which provides valuable experience and enlightenment for the hidden ore prospecting in northwest Guizhou and even the whole country.
