The authors discuss the regional mineralization law of iron ore in the area from the way of typical deposit and the regional deposit, obtaining a primary conclusion about the regional mineralizing law of iron ore including genetic type. We also believe that the iron ore mineralization of Weining north mountain area mainly occurred in Carboniferous-Permian, which is characterized by the sedimentary mineralization in the early stage and by the tectonic-hydrothermal activities in the late;the stratum and lithofacies and lithology are the main control factors of iron ore mineralization and the geologic structure’s function is minor because major mineralization is deposition, though it plays a certain positive role in mineralization. oft-com:office:office" />
