摘要

鹰咀山金矿位于北祁连加里东褶皱带的北西缘,岛弧火山岩带之西端,北距阿尔金断裂7km。以阿尔金大型走滑断裂为界,南为祁连山褶皱系北祁连加里东褶皱带,北属敦煌地块万佛峡—大坝新生代断陷盆地。本文着重介绍地质特征并提出找矿方向:①矿区深部工程工作程度低,应加大深部找矿力度;②勘查程度低,加大找矿力度;③充分利用以往化探成果,以期发现富有价值的找矿线索;④对辉长岩接触带加大工作力度,以期新发现更多有价值的矿体。
        Yingzuishan gold deposit is located in the northwest margin of the Caledonian fold belt in the North Qilian Mountains, at the western end of the island arc volcanic rock belt and 7 km north of the Altun fault. It is bounded by the large strike-slip faults in Altun, the North Qilian Caledonian fold belt in Qilian Mountain fold system in the South and the North Wanfoxia-Daba Cenozoic fault basin in Dunhuang block. This paper emphatically introduces the geological characteristics and puts forward the prospecting direction: ① the low degree of deep engineering work in the mining area should be strengthened; ② the low degree of exploration should be strengthened; ③ making full use of the previous geochemical exploration results in order to find valuable prospecting clues; ④ intensifying the work on gabbro contact zone in order to discover more valuable ore bodies.
