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。
Huayagou gold mine is located in the western Qinling Gansu Province in the southern region, is the Shaanxi-Gansu “Golden Triangle ” an important part. Based on the study of characteristics of ore-bearing construction, ore body geology and gold mineralization, this paper establishes a gold mineralization model, and points out that the gold rock output is composed of the muddy Shujiaba Group Hejiadian Formation, The body distribution is strictly controlled by the secondary faults of the ductile-brittle shear zone, and chlorite, limonite (pyrite) and silicified alteration zones are good symbols of gold discovery. It has been found that the direction of extension of the orebody and the south of No.2 orebody are favorable locations for discovering new orebody.
