鹰嘴山金矿位于阿尔金左行走滑大断裂与北祁连加里东褶皱带呈锐角相交的部位。矿床赋存于黑茨沟组一套中、酸性火山岩—碎屑岩建造的火山岩中，受ＮＷ向断裂构造控制。通过对矿床特征及成因的分析认为，矿化硅化岩是热液成因，中、酸性火山岩为矿源层，经蚀变为成矿提供了矿物质，构造控制了矿化体的分布、形态、产状。鹰嘴山金矿为火山岩中的构造蚀变岩型金矿床
The Yingzishan gold deposit is located at the intersection of the acute left-slip fault in Altun and the Caledonian fold belt in the North Qilian. The deposit is hosted in a set of the Hertzian Formation that is controlled by the NW-trending fault structure in volcanic rocks of acidic volcanic-clastic rock. Based on the analysis of ore deposit characteristics and genesis, mineralized silicide rocks are the hydrothermal genesis. Medium and acidic volcanic rocks are the source rocks. After alteration, mineralization is provided by mineralization. The structure controls the distribution and morphology of mineralized bodies. shape. The Yingzishan Gold Mine is a tectonic altered rock type gold deposit in volcanic rocks
