摘　　要：高松山金矿床是近几年在小兴安岭—张广才岭成矿带北段发现的大型浅成低温热液矿床,已探获资源量22 t,具有优越的成矿地质条件和良好的找矿前景,已被列为国家首批整装勘查区。为了揭示其成矿规律和找矿潜力,且为今后的整装勘查与资源潜力评价提供有意的参考,在分析高松山金矿床成矿地质背景和矿床地质特征基础上,研究其成矿特点,发现矿脉产出受菱形构造控制,呈等距分布,在垂向上具有向西侧伏,分段富集特征;结合成矿规律和物化探异常特征,指出矿区存在多条平行矿脉,NWW向矿体深部成矿潜力大;提出沙阿其河断裂是导矿构造,可能也是容矿构造,在下一步的勘查工作应加以重视。Gaosongshan gold deposit is a recently discovered large-scale epithermal gold deposit in the northern part of Lesser Khingan-Zhangguangcai Range metallogenetic belt, with proven gold resource of 22 t, indicating good metallogenetic conditions and prospecting potentials in this region. Based on analysis of geological settings for metallo- genesis and characteristics of ore deposit in Gaosongshan gold deposit as well as the study of its metallogenetic fea- tures, it is found that the veins are controlled by rhombus structures, distributing equidistantly, trending laterally west and enriching segmentally in vertical direction. According to metallogenetic regularities and geophysical and geochemi- cal anomalies, several parallel veins are considered to be present and so are potentials for the NWW trending deep mineralization. It is put forward that the Sha＇eqi River fracture is not only ore-transmitting structure but also ore-depos- iting structure, which should be well tended in further exploration work.
