| 摘 要： | 祁连褶皱系钨成矿与老地块密切相关,这些老地块富钨,为成矿提供了部分物质来源。大型钨矿床通常定位在NW向深断裂与NE向隐伏断裂交汇部位。加里东期的酸性侵入体对钨成矿起了决定性的作用。白钨矿矿床的形成与角闪片岩关系密切。矿区具有明显的水平分带性,中心一般为钼、铜、钨,外围为铅、锌、银。

| Abstract: | The ore-formation of wolfram in Qilian fold system is closely related to the old
blocks which are abundant in wolfram and provided part of wolfram for the formation of ore de-
posits.Large-sized wolfram ore deposits are usually located at the area where deep faults striking
northwest intersect concealed faults striking northeast.Caledonian acid intrusive rocks play a deci-
sive role in the formation of wolfram ore deposits.The formation of scheelite deposit has an inti-
mate relationship with amphibole-schist.The ore deposit usually has two zones,that is,W,Mo
and Cu are enriched in central zone,and Pb,Zn and Ag are enriched in marginal zone |
