Magnetite deposit of Pocheon Iron Mine is a contact replacement skarn deposit embedded in the carbonate rocks (limestone and dolomite) which are intruded by granite porphyry. The shape of ore bodies is sweet potato-like and/or irregular massive form; D-ore body, the biggest one is of 180m×40m×200m in size. The ore is in general of high grade. The location of the ore bodies is controlled by the fault which strikes north south and dips 60° to 70° to the west. A regular distribution of mineralized zones is recognized in order of outward (hanging wall side) from granite porphyry as follows; compact fine-grained skarn, limesilicates, magnetite ore body, marble, limesilicates, pyritized meta-sediments.
