本文对小独山西钨金矿区内的石英脉特征进行了详细的描述,并对其含矿性及其与矿化的关系进行了对比研究。发现区内出露的石英脉大致有近东西向石英大脉、近东西向石英中脉或细脉、北西向石英细脉以及显微石英脉等4种类型,其产状严格受节理控制。小独山西钨金矿的钨矿化主要由北西走向石英细脉引起,其它3种类型石英脉暂不具工业价值。含矿石英脉对围岩基本没有选择性,矿化强度与石英脉脉频和脉幅大小呈正相关关系,脉频越大、脉幅越宽,矿化越强、品位越高。单个石英脉构不成具有工业价值的矿体,密集的石英细脉+围岩构成的石英脉带可形成规模较大的工业矿体,矿床的主体矿石工业类型为石英细脉带型钨矿石。矿床目前属于低品位钨矿床,但矿床剥蚀浅,从矿化特征推测该矿床具有“五层楼”模式,在今后的工作中有望找到矿化集中的富矿地段。 In this paper, the characteristics of quartz veins in Xueduoshan gold deposit in Xiaodushan are described in detail, and the relationship between ore-bearing and mineralization is studied. It is found that the quartz veins exposed in the area generally have four types of near-to-west quartz veins, near-west quartz veins or veinlets, northwestern quartz veins and microscopic quartz veins. Their occurrences are strictly controlled by the joints. The tungsten mineralization of the Xishan tungsten gold deposit in the small Dushan Mountain is caused mainly by the northwesterly quartz veins, while the other three types of quartz veins are temporarily not of industrial value. The ore-bearing quartz veins are basically non-selective to the surrounding rock. The mineralization intensity has a positive correlation with the frequency and pulse width of quartz veins. The larger the pulse frequency is, the wider the pulse width is, and the stronger the mineralization is, the higher the grade is. A single quartz vein can not form an orebody with industrial value. The quartz vein formed by dense quartz veinlets and surrounding rocks can form a large-scale industrial ore body, and the main ore type of the ore deposit is quartz vein belt type tungsten ore. The deposit is currently a low-grade tungsten deposit, but the deposit is denuded shallowly. It is presumed from the mineralization that the deposit has a “five-storey” mode and is expected to find a rich mineralized section in the future.
