摘　　要：本文对和安河金矿地质特征及找矿标志进行了总结。矿体呈脉状、细脉状赋存于燕山期花岗闪长岩中,主要受北北西向断裂构造控制,矿石类型以含金蚀变岩型为主,其次为含金石英脉型。矿石结构以半自形晶-他形晶粒状结构为主;构造主要为浸染状构造。矿床属于中高温热液蚀变矿床,硅化、绿泥石化、黄铁矿化是蚀变矿物找矿标志,土壤测量Au元素异常是地球化学找矿标志。In this paper,the geological features and prospecting criteria of He anhe gold deposit are summarized.The ore bodies are found in vein and fine vein in Yanshanian granodiorite,which is mainly controlled by the NNW trending fracture structure.The ore type is mainly gold-bearing altered rock type,followed by type of gold-bearing quartz vein.The ore structure is mainly subhedral-heteromorphic grain structure;the structure is mainly disseminated structure.The deposit belongs to medium-high temperature hydrothermal alteration deposit.Silicification,chloritization and pyritization are the prospecting criteria of alteration minerals,and the anomaly of Au element in soil survey is the geochemical prospecting criteria.
