摘　　要：河南省新蔡县练村铁矿属大型磁铁矿矿床,赋存于新太古界太华岩群铁山岭组沉积变质地层,该矿床成因为海底火山喷流—变质改造而形成的沉积变质硅铁建造铁矿床,该矿床成因主要受地层及变质作用两种因素的影响。Liancun iron ore deposit in Xincai County,Henan Province is a large-scale magnetite deposit,which occurs in the sedimentary metamorphic strata of the Tieshanling Formation of the Taihuayan Group in the new Archean.The deposit is a sedimentary metamorphic ferrosiliceous iron deposit formed by submarine volcanic exhalation metamorphism.The genesis of the deposit is mainly affected by two factors:strata and metamorphism.
