.... Our new sensitive high-resolution ion microprobe data from 14 sandstones of the Taebaeksan Basin, Korea, indicate that its platform shelf sequences, typified by trilobite faunal assemblages diagnostic of the NCC, record the vestige of coeval arc magmatism. Detrital zircons analyzed from the sandstones...

... the macroinvertebrate fossil assemblage from the Machari Formation of the Yeongwol Group, Taebaeksan Basin, Korea, and comprises diverse trilobites of Cambrian Series 3 to Furongian, with some inarticulate brachiopods, monoplacophorans, gastropods, and hyoliths. It was partly introduced...

... Supergroup in the Taebaeksan Basin. The formation yields a variety of marine invertebrate fossils, including brachiopods, molluscs, echinoderms, corals, fusulinids, and conodonts. Diverse brachiopods are described from six siliciclastic horizons of the formation at three localities, including 23 species...

...SEUNG-BAE LEE; DUCK K. CHOI Abstract The Pseudokoldinioidia Fauna is a newly documented uppermost Cambrian trilobite assemblage from the Dongjeom Formation of the Taebaek Group, Taebaeksan Basin, Korea. It is characterized by low species diversity comprising six trilobite taxa: Micragnostus...

...SEUNG-BAE LEE; BERTRAND LEFEBVRE; DUCK K. CHOI Abstract The oldest echinoderms and first cornute stylophorans ever reported from Korea are described, based on more than 40 specimens collected from the Late Cambrian of the Taebaeksan Basin. New material doubles the number of stylophorans described...

... between the Daegi and Sesong formations is diachronous within the Taebaeksan Basin. The Daegi/Sesong formation boundary in Korea is comparable to the Zhangxia/Gushan boundary in North China in that it displays an abrupt change from a carbonate-dominant facies to a shale-dominant facies. The correlation...

... Belt; TB – Taebaeksan Basin; YM – Yeongnam Massif; HB – Hida Belt. (b) Simplified geologic map of the Taebaeksan Basin (modified after Korea Institute of Geoscience and Mineral Resources (KIGAM), 1995 ). ...

...Seung-Bae Lee; Duck K. Choi Abstract The Eosaukia fauna is proposed for the upper Furongian trilobite assemblage from the interval spanning from the upper part of the Hwajeol Formation to the lowermost part of the Dongjeom Formation in the Taebaek Group, Taebaeksan Basin, Korea. It is characterized...

... the ontogeny of the two co-occurring shumardiid trilobites, Akoldinioidia latus Park and Kihm and Koldinioidia choii Park and Kihm, from the middle Furongian Hwajeol Formation, Taebaeksan Basin, Korea. Interestingly, protaspides of the two shumardiids have a bulbous morphology. Given the stratigraphic...

.... This study deals with the ontogeny of the Furongian (late Cambrian) ptychaspidid trilobite, Quadraticephalus elongatus ( Kobayashi, 1935 ), from the Hwajeol Formation of the Taebaek Group, Taebaeksan Basin, Korea, with a special focus on the segmentation process during the meraspid pygidial development...

...SEUNG-BAE LEE; BERTRAND LEFEBVRE; DUCK K. CHOI Abstract Abundant isolated elements of cornute and mitrate stylophorans were recovered from the upper Tremadocian Tumugol Formation in the Taebaeksan Basin, Korea. Cornute skeletal elements comprise a diverse assemblage of marginals and brachials...

...PAUL S. HONG; JEONG GU LEE; DUCK K. CHOI Abstract Acid-resistant specimens of trilobites were recovered from the dissolved residues of lime mudstone collected from the lower part of the Machari Formation, Yongwol Group, Taebaeksan Basin, Korea. One of the samples yields a trilobite assemblage...
