摘要
Mengku iron ore deposit is the biggest one in Xingjiang,and it has complicated metallogenic process and genesis.Based on developmental condition,formative precedence and mutual interpenetration relationships of primary minerals association in ore bodies of different sectors,combined with structural characteristics of ores or mineralized rocks from microscope,characteristics of metallization in Mengku iron ore deposit has been summarized.Mengku iron ore deposit has experienced three metallogenic epochs:marine volcanic sedimentary metallogenic epoch,regional metamorphism metallogenic epoch,pyrometasomatic epoch.The regional metamorphism epoch is considered to be iron metallogenic epoch,while the pyrometasomatic epoch is the mineralized epoch of copper.Therefore,Mengku iron ore deposit belongs to that of superimposed metallization of multiple epochs and factors(exhalatived sedimentary,regional metamorphism and pyrometasomatic process).
