摘　　要：大吉山钨矿是位于中国南岭地区的一个典型的集石英脉型钨矿、花岗岩型钽铌钨铍钼矿及花岗闪长岩风化壳离子吸附型稀土矿于一体的超大型稀有多金属矿床。成矿与华南地区当时为挤压向伸展过渡的构造背景有关,成矿流体为岩浆—热液过渡性流体。以岩浆分异—贯入—热液作用为主,具有钽—铌—钨—铍—钼—稀土等矿化组合的复合/叠加型稀有多金属矿床。The Dajishan tungsten deposit, a super- large sized rare multi- metallic deposits in the Nanling region of China, is a typical deposit comprising quartz vein type tungsten deposit, granite type tantalum - niobium - tungsten - beryllium - molybendium deposit and weathered crust type ion adsorption type rare earth deposit hosted by granodiorite. The metallogenic process is associated with the regional tectonic background where the Southern China transited into the extensional stretch from the compressed phase, the mineralization fluid is the transitional fluid from the magma stock into the hydrothermal fluid. The mineralization is dominated by the magmatic differentiation, fluid penetration and hydrothermal activity, and formed the composite and superposition rare polymetallic de- posit consisting of tantalum, niobium, tungsten, beryllium, molybdenum and rare earth mineralization.
