| 摘 要： | 花崖沟金矿地处甘肃省南部的西秦岭地区,是陕甘川＂金三角＂的重要组成部分。本文通过对含矿建造、矿体地质、金成矿作用等特征进行研究,建立了金矿成矿模式,指出金矿产出的围岩地层为泥盆系舒家坝群何家店组,矿体分布严格受韧—脆性剪切构造带次级断裂控制,绿泥石化、褐铁矿化（黄铁矿化）及硅化蚀变带是找金的良好标志。已发现矿体的东西延伸方向及2号矿体南侧是发现新矿体的有利地段。

| Abstract: | Huayagou gold deposit is located in the west Qinling region of south Gansu Province. By studying ore-bearing formation, orebody geology, and gold mineralization etc., it is set up the metallogenic model of Huayagou gold deposit, pointed out that the wall rock of orebody is Hejiadian Formation of Devonian Shujiaba Group, orebody strictly controlled by the ductile-brittle shear tectonic belt second-order faults, chloritization,limonite, pyritization and silicification altered zone are good sign for prospecting gold. |
