| 摘 要： | 武山温泉钼矿床位于西秦岭东段多金属矿区，近年来勘查成为一个较大而且有一定找矿潜力的中一大型钼矿床。岩体呈巨大岩基状产出的中浅成杂岩体，出露面积253．68km^2。印支晚期超浅成细粒黑云母二长花岗岩（γ5^1-10）（岩株）对钼矿床的最终形成及矿化富集有明显的活化作用。矿区以近NNW向主干断裂为导矿构造，次级裂隙（节理）为容矿构造，尤其以向东倾的一组裂隙（节理）为主要的含矿构造。控矿因素主要为“岩相”＋构造的二元模式。

| Abstract: | Wenquan Molybdenum deposit in Wushan County is situated in the multi-metal mineral district within the eastern section of west Qinling,which is believed to be a potential middle-large scale molybdenum deposit through a series of recent explorations.Rock mass is a middle shallow complex,the occurrence of huge batholith with the exposed area of 253.68km2.The super shallow fine granular biotite adamellite,formed at late Indo-Chinese epoch,acted as a role of obvious activation on the formation of molybdenum deposit and mineralization enrichment.NNW-striking main fault in the mineral district is the main ore transmitting structure,secondary fissures(joints) is the host structures,among which a series of fissures dipping east towards is main host structure.Factors of ore controlling is the model of lithofacies and structures. |
