内蒙古金厂沟梁金矿床成矿机制研究及成矿预测的开题报告 【摘要】 随着能源和金属矿产资源的渐趋枯竭，探测新矿床已成为地质工作的重点之一。 内蒙古金厂沟梁金矿床是一个具有潜力和前景的未开发矿床，但尚未有详细的矿床形成机制研究。为了对其形成机制进行研究，本研究采用地质、地球化学、矿物学等方法，对该矿床的地质特征、地球化学特征、矿物组成等进行了分析和研究。研究结果表明，内蒙古金厂沟梁金矿床的成因类型为岩浆热液型和构造变质型，均受到区域构造的控制。岩浆热液型主要形成于侵入岩体和火山岩体的接触带和矿化升华带，有较高的Au, Ag, As, Sb, Hg等金属元素含量；构造变质型主要分布在区域断裂带的内部和附近，具有较高的Au, Ag, Pb, Zn等金属元素含量。由此可以预测，内蒙古金厂沟梁金矿床具有较高的开发潜力。 【关键词】 内蒙古金厂沟梁金矿床；成因类型；岩浆热液型；构造变质型；矿床形成机制；开发潜力 【Abstract】 With the depletion of energy and metal mineral resources, exploring new ore deposits has become one of the focuses of geological work. Jinchanggouliang gold deposit in Inner Mongolia is an undeveloped deposit with potential and prospect, but detailed research on the formation mechanism of the deposit has not been conducted. In order to study its formation mechanism, this study used geological, geochemical, mineralogical and other methods to analyze and study the geological characteristics, geochemical characteristics, mineral composition, etc. of the deposit. The results show that the type of genesis of Jinchanggouliang gold deposit is magmatic hydrothermal type and structural metamorphic type, both of which are controlled by regional tectonics. The magmatic hydrothermal type is mainly formed in the contact zone and mineralization sublimation zone of the intrusive rock and volcanic rock, and has high contents of metal elements such as Au, Ag, As, Sb, and Hg; the structural metamorphic type is mainly distributed inside and near the regional fault zone, and has high contents of metal elements such as Au, Ag, Pb, and Zn. Therefore, it can be predicted that Jinchanggouliang gold deposit in Inner Mongolia has high development potential. 【Keywords】 Jinchanggouliang gold deposit in Inner Mongolia; type of genesis; magmatic hydrothermal type; structural metamorphic type; formation mechanism of the deposit; development potential
