大吉山钨矿和赣南其他钨矿床一样,均属高中温热液裂隙充填石英脉型的黑钨矿床,矿脉一般成群分布,分细脉带和大脉群两种类型,前者呈密集网状或近似平行状产出,脉幅小,脉间距亦小;后者多为近似平行状,脉幅较大,脉间距亦较大。矿体倾角 Like other tungsten deposits in southern Jiangxi, the Dajianshan tungsten deposit belongs to the high-temperature hydrothermal fissure filling quartz vein type black tungsten deposit. The veins are generally distributed in groups and are divided into two types: Shaped or nearly parallel-shaped output, a small pulse, pulse distance is also small; the latter are mostly parallel, larger pulse width, pulse distance is also larger.
