///Study on the regional geology and metallogenesis of the iron deposits in Anshan-Benxi area, Liaoning Province shows that the iron deposits, hosted in the late Archean granite-greenstone belts, are dominated by banded iron formation (BIF) type. The major ore-bearing beds are Cigou and Yingtaoyuan rock formations of Anshan Group. The ores are in banded and massive structures, with hypidioblastic and relict textures. The evolution trend of the iron formation is closely related to volcanic activity. The most advantageous positions of searching for large and superlarge deposits is the Anshan-Benxi sag area, as well as the areas with high magnetic anomaly, complex magnetic anomaly, low-gentle magnetic anomaly,  big deep magnetic anomaly and residual magnetic anomaly.
