| 摘 要： | 贵州独山锑矿集区是中国泥盆系锑矿重要成矿区,成矿地质条件优越,先后在区内发现探明了1个大型、2个中型、5个小型及13个锑矿(化)点。在系统分析锑矿成矿地质特征、地球化学、地球物理、遥感影像特征基础上,总结了独山锑矿集区地层及岩性、构造、蚀变、地球化学、遥感、地球物理找矿标志。在半坡锑矿床深部找矿中,运用"CSAMT解译封闭高阻体+成矿断层"地球物理标志,结合钻探工程发现了新的隐伏锑矿体,实现了深部隐伏矿找矿突破。通过综合研究地物化遥异常信息,依据勘查标志,圈定和优选出丰坡外围、弄江—贵修—甲拜—贝达地区、维寨地区三个找矿靶区。在今后综合勘查中,通过探测技术的优化集成和老(矿)点新评,有望实现新的找矿突破。

| Abstract: | The Dushan antimony ore concentration area in Guizhou Province is one of the most important Devonian antimony metallogenic regions. It has superior ore-forming geological conditions and abundant mineral resource. In the Dushan antimony ore concentration area,1 large, 2 middle, 5 small and 13 antimony ore spots have successively been found. Based on antimony metallogenic conditions, geochemical anomaly, geophysical anomaly and remote sensing image interpretation, the authors summarized exploration indicators of strata and lithology, tectonic, alteration, geochemistry, remote sensing and geophysics. In the prospecting toward the deep subsurface of the the Banpo antimony deposit in Dushan County, the authors used exploration indicators of metallogenic fault, closed high resistance body of geophysical anomaly from CSAMT geophysical anomaly, drilled engineering validation holes, found a new concealed rich antimony orebody, and achieved a deep concealed ore prospecting breakthrough. In the comprehensive study of various kinds of abnormal information and on the basis of exploration marks, the authors delineated and optimized the three prospecting target area of Banpo periphery, Nongjiang-Guixiu-Jiabai-Beida and Weizhai areas. In the course of ore comprehensive prospecting in the future, it is expected to achieve new prospecting breakthrough through optimization and integration of detection technologies and new evaluation of the old mine. |
