    Research on the site selection of Nanling Scientific Drilling-1

    • 摘要: 提要:赣南银坑矿田作为中国深部探测实验研究在南岭成矿带的首批示范区,以探索深部矿产资源成矿规律为主要目标,先后开展了地质实测剖面、地球化学测量、矿田构造、岩浆活动、典型矿床和综合地球物理探测研究,认识到矿田内中高温热液型钨多金属矿床和中低温金银铅锌铜贵多金属矿床分带性在二维平面空间内的存在。通过区内岩浆活动与典型矿床研究,发现两类矿床的形成在时间、空间、物质来源和成矿作用方面分别与燕山早期的两套岩浆活动密切相关,建立了精确的成岩成矿年代学格架,确立了两类矿床在时空三维上存在着成因联系。应用高精度重磁面积测量和骨干剖面的大地电磁、反射地震和CSAMT/AMT等探测方法,开展了综合地球物理探测研究,初步探明了区内地层-岩体-构造的深部结构,为南岭科学钻探选址(SP-NLSD-1)提供了科学依据。南岭科学钻探旨在揭示南岭与武夷成矿带交汇部二层结构的成矿作用,探索南岭地区时空四维成矿规律。

       

      Abstract: Abstract:The Yinkeng ore field in Jiangxi Province is one of the first prior research targets of Sinoprobe-Deep Exploration in China, with the exploration of the ore-forming regularity of deep mineral resources as the main aim. Geological exploration profiling survey, geochemical survey, ore field structure, magmatism, typical ore deposits and integrated geophysical studies were conducted in this region. It is revealed that hypothermal W-polymetallic deposits and mesothermal Au-Ag-Cu-Pb-Zn polymetallic deposits characterized by metallogenic zoning are existent in 2D space. According to the study of ore-forming regularity of magmatism and typical deposits, the authors hold that the two types of ore deposits are temporally, spatially, and genetically closely associated with the two series of magmatic activities at the early stage of Yanshanian period. Accurate rock-forming and mineralization chronology framework was established, which suggests that the two types of deposits have space-time relationship. By using high-accuracy gravity and magnetic area survey and the detection methods of major cross-sections such as ground magnetic survey, seismic reflection, and CSAMT/AMT, the authors carried out comprehensive geophysical detection research, and primarily determined the deep structure of strata-rock body-structure. The results obtained by the authors provide the scientific basis for the site selection of Nanling scientific drilling (SP-NLSD-1) (Fig.2). Furthermore, it is revealed that dual-layer structure of mineralization may be exist in the Yinkeng ore field, which contributes to the further research on the ore-forming regularity of Nanling region in 4D time-space.
