Abstract: The limeyaogou iron ore area is about 80 km away from the northwest of Chifeng City, and is located in the south side of the Xilamulun polymetallic metallogenic belt. The area is located in the contact zone between the east part of Inner Mongolia earth axis and the West Inner Mongolia sea fold belt. The third level structural unit is the northeast end of Yunwushan uplift and the boundary of the two structural units of Chifeng Mingshan fracture. The wall rock alteration of the deposit is zonal, and it is a fault and Skarn type deposit controlled by fold complex. In order to explore the geological characteristics and ore prospecting signs of the mining area, the geological survey work in this area has been summarized and analyzed in recent years. The deposit is considered to be a skarn deposit. Around the structural development position, the main prospecting target is the contact zone between the rock mass and the stratum and the adjacent area and the highprecision magnetic anomaly matching area.
