摘　　要：河南老湾金矿带勘查程度、研究程度较高,找矿成果丰富。同处北淮阳构造带的安徽霍山金矿化带找矿一直未取得新的进展。本文通过金矿带空间分布特征、基底地层、控矿构造、岩浆岩、典型矿床特征等类比,探讨成矿时代、成矿类型、成矿机制,认为霍山金矿与老湾金矿相似,揭示了霍山金矿化带深部与老湾金矿类似的构造蚀变岩型金矿具有较大的找矿潜力。Both the Laowan gold belt, Henan and the Huoshan gold mineralization belt, Anhui are located in the northern Huaiyang tectonic belt, and the former has been highly explored and studied, with abundant work results, however, the latter has not seen any new progress in gold exploration. By comparing spatial distribution characteristics, strata in the basement,ore-controlling structures, magmatic rocks and typical deposit characteristics, this paper discusses the age, type and mechanism of the metallogenesis, and concludes that the Huoshan gold deposit is similar to the Laowan gold deposit, and there is a good potential in the deep part of the Huoshan gold mineralization belt for prospecting tectonic alteration rock type gold similar to that in the Laowan gold deposit.
