%X 大吉山钨矿床为南岭众多钨矿床中较为特殊的矿床&#65292;&#8220;五层楼加地下室&#8221;的垂直分带模式为该矿床的一大特色&#65292;前人对其做了许多研究&#65292;积累了大量资料。通过系统总结前人研究成果&#65292;文章取得了以下认识&#65306;&#9312; 大吉山钨矿床形成于燕山早期&#65292;为华南地区中生代大规模成矿作用(170~150 Ma)的产物&#65307;&#9313; 矿区成矿为多期次、多阶段的演变过程 &#9314; 成矿物质主要来自于本区的花岗岩浆 &#9315; 成矿流体主要为岩浆&#65292;后期则有大气降水混入&#65307;&#9316; 矿床为中高温矿床&#65292;成矿流体有多期次、中&#8211;低盐度的特征&#65292;钨矿形成与流体不混溶作用有关&#65292;而铌钽矿形成则与流体自然冷却有关。&#9317; 矿床花岗岩体为S型花岗岩&#65292;有着高度分异演化程度。<br>The Dajishan tungsten deposit is a special deposit among most tungsten deposits in Nanling. The distribution pattern of veins in five-floor building and basement is a major feature of this deposit. Many studies have been done and a lot of data have been accumulated. By systematically summarizing the previous research results, the following conclusions are obtained. &#9312; The Dajishan tungsten deposit was formed in the early Yanshanian period and was the product of large-scale Mesozoic mineralization (170~150 Ma) in South China. &#9313; The ore-forming process has the multi-stage characteristics. &#9314; The ore-forming material mainly comes from the granitic magma in the area. &#9315; The ore-forming fluid mainly comes from magma. &#9316; The deposit is a medium-high temperature deposit, and the ore-forming fluid has the characteristics of multi-stage and medium-low salinity. The formation of tungsten ore is related to fluid immiscibility, while the formation of niobium-tantalum ore is related to the natural cooling of fluid. &#9317; The granite of the deposit is S-type granite with a highly differentiated evolution degree.
