摘要:
新疆阿尔泰以发育VMS型多金属矿、与海相火山作用有关的铁矿、伟晶岩型稀有金属矿和造山型金矿为特色, 近年来新疆维吾尔自治区有色地质勘查局地质矿产勘查研究院发现了巴斯铁列克中型钨多金属矿, 这是首次在阿尔泰发现的钨矿, 拓展了阿尔泰找矿思路。巴斯铁列克钨多金属矿赋存于矽卡岩中, 成矿过程划分为早期矽卡岩阶段、退化蚀变阶段和石英-硫化物阶段, 其中退化蚀变阶段是白钨矿主要成矿阶段, 石英-硫化物阶段是铜锌金的主要成矿阶段。切穿多金属矿体的伟晶岩脉锆石LA-Q-ICP-MS U-Pb加权平均年龄为275.4 Ma, 矿石中辉钼矿Re-Os等时线年龄为284.4 Ma, 厘定巴斯铁列克钨多金属矿形成于284 Ma, 属早二叠世成矿。成矿时代及岩体年龄表明, 巴斯铁列克钨多金属矿的形成与矿区西可斯尔鬼黑云母二长花岗质岩浆期后热液交代康布铁堡组大理岩和变粒岩形成的矽卡岩有关。
Abstract:
The Altay area in Xinjiang is famous for its abundant mineral resources such as VMS polymetallic, submarine volcanogenic iron, pegmatite type rare metals and orogenic gold deposits. Recently, the Basitielieke medium-sized tungsten polymetallic deposit was discovered by Geological and Mineral Prospecting Research Institute of Nonferrous Geological Prospecting Bureau of Xinjiang Uygur Autonomous Region, and it is the first tungsten deposit discovered in the Altay area. The Basitielieke tungsten polymetallic deposit occurs in the skarn, and its metallogenetic process can be divided into prograde, retrograde and quartz-sulfide stages. The scheelite and Cu-Zn-Au mineralization were formed in the retrograde stage and quartz-sulfide stage, respectively. Field observation indicates that the formation of the Basitielieke tungsten polymetallic deposit is closely related to the skarnization of the marble, and granulite of the Kangbutiebao Formation which was metasomatized by the post-magmatic hydrothermal fluids of the Kesiergui biotite monzonitic granite. Zircon from the pegmatite dike that cut through the orebodies yielded U-Pb weighted average age of 275.4±2.6 Ma, while molybdenite from the ores yielded Re-Os isochron age of 284.4±5.5 Ma. Therefore, the Basitielieke deposit was likely formed at ca. 284 Ma, which belongs to the Early Permian metallogenesis.
