新疆西天山喀腊萨依钨矿地质特征及找矿意义

新疆西天山喀腊萨依钨矿是在赛里木铜多金属矿带发现的。作者基于野外地质调查,对矿床地质特征进行了总结,认为矿床赋存于晚石炭世花岗岩体远接触带附近上泥盆统托斯库尔他乌组细碎屑岩地层中,含矿地质体为白钨矿化石英脉(带),受倾向SSW的较陡倾斜的一组节理裂隙控制,矿床成因属石英脉型钨矿。通过对矿床区域成矿环境的分析,认为应注意在矿床所在的库松木切克山一带寻找与华力西中晚期S型花岗岩有关的高温热液型钨、锡、钼、稀有元素矿产。

Geological characteristics and prospecting significance ofKalasayi tungsten deposit in western Tianshan mountain, Xinjiang

The Kalasayi tungsten deposit located in the western Tianshan, Xinjiang was first discovered in the Sailimu Cu-Au-Ag polymetallic metallogenic belt. The author summarized the geological characteristics of ore deposit on the basis of detailed field survey, and it was concluded that the ore body is hosted by the upper Devonian clastic rocks of the Tuosikuer formation adjacent to the contact zone of the late Carboniferous granitic intrusion. The scheelite-bearing quartz vein is controlled by a group of sharply SSW-dipping fractures. Through the analysis of regional metallogeny, it is suggested that there is a great prospecting potential for hydrothermal type tungsten, tin, molybdenum and rare elements deposits which were genetically related to middle and late Variscan S-type granite in the Kusongmuqieke mountain region.
