摘　　要：在前人研究基础上,综述阿尔泰铁矿地质背景和主要矿床地质特征,将阿尔泰铁矿划分为火山岩型、矽卡岩型、伟晶岩型、热液型、岩浆型、沉积变质型和砂矿等7种类型。铁矿集中分布于哈巴河县齐叶-凯勒克赛依、克兰盆地、麦兹盆地、富蕴县城、乔夏哈拉-老山口、查干郭勒等地区,成矿时代划分为中—晚奥陶世,早泥盆世（410~385Ma）,中泥盆世（380~375 Ma）,早—中二叠世（287~261 Ma）和三叠纪（255~203 Ma）,成矿过程经历俯冲阶段、后碰撞阶段和陆内演化阶段。This paper summarized the previous research, and divided the iron deposits in Altay into seven types based on geological setting and geological characteristics of main deposits,e.g. volcanic rocks,skarn,pegmatite,hydrothermal,magmatic,sedimentary metamorphic,and placer types.These iron deposits are spatially distributed in Qiye-Kailekesaiyi in Habahe County,Kelan basin,Maizi basin,Fuyun County,Qiaoxiahala-Laoshankou,and Chaganguole,and can be temporally divided into five periods：Middle-Late Ordovician,Early Devonian（410~385 Ma）,Middle Devonian（380~375 Ma）,Early-Middle Permian（287~261 Ma）,and Triassic（255-203 Ma）.Theses deposits formed in subduction,post-collision and intracontinental setting.Summary on metallogenic regularity of iron deposits in Altay can provide some basis for the further exploration work.
