摘　　要：结合近年来在大兴安岭成矿带取得的最新工作成果,认为可将大兴安岭北段金矿床划分成3个主要成矿区带,存在3次规模较大的金矿化作用,归纳和总结出2个主要金矿床成矿类型。通过对本研究区内典型矿床(点)的系统分析,确立金矿床找矿标识特征,为找矿实践提供理论指导和方法指南,以期实现找矿工作的重大突破。Combining with the latest achievements obtained in Northern Daxing＇anling metallogenetic beh in recent years,it is considered that the northern gold deposits of Daxing＇anling can be divided into three main metallogenetic belts. There are three large-scale gold mineralization zones, and two main gold mineralization types are summarized. By systemati- cally analyzing the typical deposits（ points ） in this area, the gold deposit prospecting identification is determined ,which pro- vides the theoretical guidance and methodological guidelines for the ore prospecting in practice to achieve a major break- through in ore-prospecting.
