摘　　要：大秃顶子金矿为赋存于下古界呼兰群东南岔组地层中的脉状蚀变破碎带型矿床,浊积岩型金矿床。矿体严格受北东向背形构造右翼地层层间形成的滑脱构造控制,金矿体就位于滑脱构造面上,目前控制金矿体3条。该文对矿床的构造背景、矿床地质特征进行了阐述,对金矿床成因进行初步探讨,为该区域今后金矿找矿有指导意义。Datudingzi gold deposit occurs in the Dongnancha Formation of Hulan Group,Lower Proterozoic earthem,it is vein altered fracture zone and turbidite-hosted gold deposit. The ore bodies are strictly controlled by detachment structure which occurs in the back-shaped structural right of North East between layers, the gold ore bodies are located on the detachment structure surface, three gold ore bodies are controlled at present. This paper expounds the tectonic background and the geological features of the deposit, preliminary study on the genesis of the gold deposit, guiding significance for gold prospecting in the region in the future.
