Description
Summary:The Taebaek Group (Cambrian-Ordovician) in theTaebaeksan Basin comprises mixed carbonate-siliciclastic sequenceand is exposed well in the Seokgaejae section located in the central-eastern part of the Korean Peninsula. The group in the Seokgaejaesection consists of in ascending order the Myeonsan, Myobong,and Duwibong formations. This study describes in detail the well-exposed outcrop sections of the Taebaek Group in the SeokgaejaePass in order to refine the lithostratigraphy of the lower Paleozoicstrata in the Taebaeksan Basin, Korea. The refined lithostratigra-phy delineates clearly the lithologic boundary between the Myobongand Daegi formations, the Hwajeol and Dongjeom formations, theDumugol and Makgol formations, and the Makgol and Jigunsanformations. The preliminary information on trilobite faunal asem-blages suggests that the Cambrian-Ordovician boundary can beplaced within the lowermost part of the Dongjeom Formation. KCI Citation Count: 54
