    Metallogenic law and exploration prospect of the middle part of Nanling metallogeny belt

    • 摘要:
      研究目的 南岭中段是中国重要的有色金属、能源矿产、非金属和水气矿产资源基地,成矿地质条件优越、矿产类型丰富、成矿作用类型复杂,深入理解其成矿规律是开展区域成矿理论研究和实现找矿突破的关键。
      研究方法 本文基于前人丰硕的成果资料,对南岭成矿带中段成矿规律和找矿方向进行了总结分析。
      研究结果 此次研究明确了南岭中段主要控矿地质条件,厘定了区域两种构造格架体系的控矿作用;依据矿产资源特征,总结了成矿特征、规律及其演化,进一步探讨了区域岩浆演化和成矿潜力;整理出了南岭成矿带中亚带目前发育的50个矿种、872处矿产地和15种矿床类型,并探讨了主成岩作用特征、演化及其成矿潜力。
      结论 南岭中段找矿的主攻方向为:寻找接触带附近的铀矿、煤矿的滑覆构造、受变质和硫铁矿区风化型铁矿、有色金属组合的综合预测和寻找缺位类型,寻找新类型稀有、稀散矿和独立金矿,保护和开发伴生宝石矿。围绕着骑田岭及周边、乐昌—韶关—翁源远景区,有望实现钨锡钼铋铜铅锌铀稀土等矿产的找矿突破。

       

      Abstract:
      This paper is the result of mineral exploration engineering.
      Objective The middle part of Nanling metallogeny belt, an important resource base of non–ferrous metal, energy minerals, non–metallic minerals, groundwater and gas minerals, has superb metallogenic geological conditions, abundant mineral types and complex mineralization types. In depth understanding of the metallogenic law is the key to carry out regional metallogenic theory research and to achieve prospecting breakthrough.
      Methods In this paper, the metallogenic regularity and prospecting direction of the middle part of Nanling metallogenic belt are summarized and studied on the basis of the abundant previous data.
      Results The main ore–controlling geological conditions are identified and the two ore–controlling structure frameworks are determined in the middle part of Nanling metallogeny belt. Depending on the characteristics of mineral resources, the metallogenic characteristics, rules and evolution are summarized, and regional magmatic evolution and metallogenic potential are further discussed. Moreover, 50 minerals, 872 ore deposits and 15 deposit types developed in the middle part of Nanling metallogeny belt are sorted out, and the predominant magmatism characteristics, evolution and metallogenic potential are discussed.
      Conclusions The prospecting of the middle part of Nanling metallogeny belt should be focused on: comprehensive prediction of U ore near the contact zone, sliding overburden structure of coal mine, metamorphic and weathering type Fe ore in pyrite mining areas, comprehensive prediction and exploration of missing types of non–ferrous metals, exploration new types of rare and scattered metals and independent Au ore, protection and exploitation the associated gem mine. Two important prospecting potential areas, which include Qitianling and its surrounding, and Lechang–Shaoguan–Wengyuan, are proposed for the key region for prospecting breakthrough of tungsten, tin, molybdenum, bismuth, copper, zinc, uranium, rare earth, etc.
