摘 要：Early Ordovician (Late Tremadoc) graptolites are procured from the nine sections of the Yeongwol area, Korea: the Dojang-gol, Ugga-gol, Karae-jae, Ppelchigol, Dae-gol, Myungjeon, Namaeri, Dumok, Namkyo Sections, which contain the boundary between the Mungok and Yeonghung Formations. The boundary between the Mungok and Yeongheung Formations reveals the ribbon rock, marlstone to shale, and grainstone to packstone facies of the Mungok Formation, and the thin laminated lime mudstone, bioturbated limestone, and wackestone to grainstone facies of the Yeongheung Formation.
