Abstract
We investigated the zircon U-Pb ages of the metapelites from the Sungjeon-myeon Gangjin-gun, the southwestern Ogcheon belt, to provide geochronological constraints for the depositional age as well as the distribution of Late Paleozoic formation. Data from the detrital zircons are mostly concordant, yielding four major age groups: (1) Neoarchean (~2.5 Ga); (2) Paleoproterozoic (~1.86 Ga, Statherian); (3) Middle Devonian(~390 Ma); and (4) Late Paleozoic (~322 Ma, Serpukhobian). The youngest zircon age gives a weighted mean $^{206}Pb/^{238}U$ age of $322{\pm}4.8$ Ma (n=16, MSWD=4.9), indicating deposition age of Early Carboniferous(Serpukhobian) or after. Therefore, the metapelites is considered to be the lowest Formation of the late Paleozoic Pyeongan Supergroup correlated with the Manhang Formation of the Samcheock coal fields and the Oeumri Formation(the Middle to Late Carboniferous) of the Hwasun coal field.
