摘要:
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。
Abstract:
The Pantuoshan granite lies in the uplift zone of the passive continental margin, north to the suture zone between the Tarim and Kazakhstan plates, where a new tungsten deposit was discovered years ago. The tungsten ore bodies can be divided into contact zone type and quartz veinlettype. The contact zone type tungsten ore bodies lie in the inner contact zone of the Pantuoshan granite, controlled by the inner contact zone and NE faults. The quartz veinlettype tungsten ore bodies are controlled by NE, EW and NW faults. The ore mineralization is obvious zonated, the molybdenite ore bodies underlain the tungsten ore bodies. Combined with regional geological setting and the geological characteristics of the deposit, the authors suggest that the indicators for this type of tungsten deposit in this area include: the activated ancient continental crust, tungsten geochemical anomaly, Stype granite, inner contact zone, wallrock alteration (tourmalinization, greisenization, silicification, etc.), quartz vein, granitic aplite dyke and direct mineralization clues.
