  • Musan iron deposit in North Korea and iron deposits in Anshan-Benxi area in China are Archean banded iron formations and included in Longgang block in Eastern block of North China Craton. Host formations of Musan iron deposit and Anshan-Benxi iron mineralized belt are Musan group and Anshan group, respectively. These groups consist of magnetite-bearing quartzite, amphibolite, schist, and migmatite. Host rock of banded iron formation in Musan deposit and Anshan-Benzi mineralized belt is magnetite-bearing quartzite. Shape of ore bodies in Musan deposit is horse's hoof due to the fold while shape of orebodies in Anshan-Benxi mineralized belt is layer. The previous studies revealed the both of banded iron formations are contemporaneously deposited during the late Archean (Musan deposit and iron deposits in Anshan-Benxi area: 2.66-2.52 Ga and 2.55-2.53 Ga, respectively). Musan deposit and iron deposits in Anshan-Benxi mineralized belt belolng to Algoma type BIFs. In conclusion, the characteristics of geology, formation ages, and deposit types of Musan deposit and Anshan-Benxi minerlized belt are very similar.
