摘　　要：火山岩型铁矿与火山活动有关,也是中国铁矿的主要类型之一。近年来,在找矿方面取得了重大突破,但研究较为滞后。该类型铁矿床的研究始于20世纪拉科铁矿床的发现,之后在全球各地发现诸多类似的铁矿床;其背景可以划分为优地槽褶皱带型、大陆边缘造山带型、断陷盆地型和深断裂带型。这些矿床与火山活动有着密切的关系,并可划分为矿浆喷溢型和火山热液型,不同类型的矿床有着不同的成因假说。研究认为磁铁矿成分、成矿年龄、矿质来源是今后火山岩型铁矿研究的发展方向。The volcanite-type iron deposit is one of main types for the iron deposits in China,whose metallization is related to the volcanic action.But the relevance study is far later than its mineral prospecting,where some great breakthrough had been made.This paper has made a review on the present research situation,such as definition,origin,tectonic setting,classification,feature and genetic hypothesis of this type deposits.The results show that the tectonic background of these iron deposits can be divided into eugeosyncline fold belt,continental margin orogenic belt,faulted basin and deep fracture zone.And these deposits are closely related to volcanic activity,which can be classified as mineral pulp-type and volcanic hydrothermal-type.Finlally,it＇s believed that the magnetite component,metallogenetic age and origin will be the research topics of these iron deposits in future.
