Abstract The Chamatun iron deposit is of a sedimentary metamorphic type buried beneath the Mesozoic volcanic sedimentary rocks with large orebody, shallow burial depth and great potential of deep resources. By applying the 3D geological modeling software Creatar and collecting borehole data, the authors establish geological database and generate 3D drilling. The 3D model of orebody is set up through section definition, single engineering delineation of orebody, section editing and surface connection. The 3D geological model of Chamatun iron deposit is built based on the thought of "point-line-plane-volume". The model shows that the iron orebody is distributed in NEE direction, with southwest part inclined to northwest and the northeast part inclined to southeast, thus prospecting should be accordingly deployed. The compound relation between orebody and magnetic anomaly indicates that the south of No. 2 orebody has great prospecting potential, and the south and northeast of Chamatun village could be the key for further prospecting and exploration.
