摘要:甘肃玉山钨矿位于甘肃北山造山带南缘、柳园-玉山板块缝合带西侧,区内构造复杂,岩浆活动强烈.主矿体形态比较规则,矿化较连续,矿体中矿化主要为白钨矿伴生有董石,以细脉浸染状为主.通过研究矿床地质特征及矿石中元素种类与含量,发现该矿床的形成与岩浆热液关系密切,再综合区内构造、地层和岩浆岩的特点,由岩
浆期后热液成矿机制,可初步得出玉山钨矿的矿床成因模式关键词:玉山钨矿;矿床成因;成矿模式

Abstract: Yushan Tungsten Mine in Gansu Province is located in the south side of Gansu Beishan orogenic belt, and the west side of the plate suture zone of Liuyuan yushan. The mining area has complex structures and intensive magmatic ac-tivity. The main ore bodies have regular morphology and consecutive mineralization. The main mineralization type is scheel-ite. It is found that the formation of mine is closely related with magmatic hydrothermal after the geological features of ore deposit and the type and contents of elements in ore are explored. Then it releases the generalization of characteristics of in-ner structure, stratum and magmatic rock, At last, the metallogenic mechanism of post magmatic hydrothermal is used to get the radical ore forming model of Yushan Tungsten Mine.
Key words: Yushan tungsten mine; ore genesis; metallogenic model
钨是我国优势矿产资源,其产量和出口量均居世界之首,约75%的钨资源来自中国.近些年来黑钨矿资源越来越显得不足,白钨矿替代黑钨矿已成必然趋势.寻找高品位高质量的白钨矿,对稳定我国钨业可持续发展具有重要的战略意义和现实意义,经过勘查,在甘肃北山造山带南缘柳园-玉山板块缝合带数百平方公里地区发现地球化学W异常,并相继找到了白山、玉山、珍石峰等钨矿点,初步显示该矿带有寻找钨资源的巨大潜力,如在玉山钨矿区找到品位高、规模大的白钨矿床,对指导该成矿带钨

玉山钨矿区位于甘肃省北山南带的东侧,属甘肃省酒泉市金塔县天苍乡管辖.处于古生代笔架山-柳园造山带之南缘,同时也位于塔里木、中朝、西伯利亚板块之间的构造衔接带1-3].在漫长的地质历史上,经过复杂的地质演化和碰撞造山活动,伴随着区域成矿作用,形成一条多金属成矿带,玉山钨矿就是这一构造一岩浆活动中形成的柳园-玉山钨成
