【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萤石,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.更多还原

【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 activity.The main ore bodies have regular morphology and consecutive mineralization.The main mineralization type is scheelite.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 inner 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.更多还原
