位于塔里木板块与哈萨克斯坦板块缝合带南侧被动陆缘隆起区的盘陀山花岗岩体中,近年新发现了钨矿床。钨矿体产于岩体北部边缘内接触带及岩体中部,成矿类型分别为接触带型和石英细脉带型。接触带型钨矿受岩体内接触带和NE向构造裂隙双重控制。石英细脉带型钨矿受NE向、EW向和NW向构造裂隙控制,矿床分带明显,具有上钨下钼的特点。结合区域地质背景及矿床成矿地质特征,初步认为本区花岗岩有关接触带型和石英细脉带型钨矿床的找矿标志为:古老陆壳活化背景、钨地球化学异常、地壳重熔型花岗岩、岩体内接触带、岩石蚀变(电气石化、云英岩化和硅化等)、石英细脉带、花岗细晶岩脉和直接找矿线索。对该矿床成矿特征和找矿标志的研究有利于推动北山地区钨矿找矿工作。
Tungsten deposits have been newly discovered in the granite of the Putuo Mountain, which is located in the uplift zone of the passive continental margin to the south of the suture zone between the Tarim plate and the Kazakhstan plate. The tungsten ore body is produced in the inner contact zone and the middle part of the rock mass in the northern margin of the rock mass, and the metallogenic types are contact zone type and quartz vein zone type respectively. The contact zone tungsten ore is controlled by both the contact zone in the rock mass and the NE-directed structural fracture. Quartz vein-type tungsten ore is controlled by NE-trending, EW-trending and NW-trending structural fractures. The deposit is obviously zonally and has the characteristics of molybdenum on tungsten. Based on the regional geological background and the mineralization geological characteristics of the ore deposits, it is initially considered that the ore-prospecting signs of the contact zone type and quartz vein belt type tungsten deposits in this area are: the ancient continental shelf activated background, tungsten geochemical anomaly, crustal remelted granite , Contact zones in rock mass, rock alteration (electrotitization, dolomitization, silicification, etc.), quartz veins, granite prickly veins and direct ore prospecting. The research on the ore-forming characteristics and ore-prospecting indicators of this deposit is conducive to promoting tungsten ore prospecting in Beishan area.
