摘要
In this paper, the authors summarized the current status of iron-ore resources in China, and proposed the factors which influence screening object iron geological data based on the iron ore deposit types, mineralization areas (belts) and occurrence characteristics. The results indicate that deposit types of iron deposits in China are dominated by the sedimentary-metamorphic type, followed by the magmatic type and contact alteration-hydrothermal type. Screening of object iron-ore geological data should consider scales of iron-ore deposits, genetic types, metallogenic epochs, and mineralization areas (belts), as well as the typical iron deposits with enormous potential.
