The Shinyemi iron deposit, one of the biggest Fe deposits in South Korea, is proximal polymetallic deposits along the contact between the Cambro- Ordovician Makgol formation of the Joseon Supergroup and the Cretaceous granitoid. According to spatial location of the ore bodies, it can be divided by eastern Pb-Zn-Mo orebody and western Fe-Mo orebody. In recent boring data, these Shinyemi granitoid was intruded along gentle slope of Makgol carbonates and proximal iron orebody formed at both upper and lower part of the subvolcanic intrusives. The lower (eastern) orebody was transformed from the proximal Fe skarn at the bottom to a transitional Zn-CuMo skarn at the top. On the other hand, the upper (western) orebody exhibits predominant Fe-mineralization with brecciation. The aims of this study are to present and document characteristics of related igneous rocks and to discuss the evolution of skarn and ore formation model in the Shinyemi polymetallic mineralogical deposits.
