The Machari Formation in the Yeongweol area consists of two informal members: namely the lower, ca. 100 meters in thickness, dark-gray to black shales containing locally interbedded dark-gray sandstone and lime mudstone, and the upper, about 320 meters in thickness, gray to dark-gray thin-bedded limestones, showing peculiar banded appearance. Two conodont faunal assemblages are recognized in the formation. The lower one is characterized by the occurrence of Gapparodus bisulcatus, Westergaardodina matsushitai, W. moessebergensis, Furnishina triangulata, Muellerodus cambricus, M. oelandicus and Nogamiconus sp., and the upper assemblage includes Cambroositodus cambricus, Proconodontus muelleri, P. cf. posterocostatus, Prosagittodontus eureka?, Teridontus nakamurae and T. n. sp. These conodont faunas suggest that the lower assemblage is correlatable with the fauna of the lower member of the Hwajeol Formation in Korea, the condount fauna of the early Late Cambrian of Northern Europe and North America, and the Kushan Formation (Westergaardodina matsushitai Zone) in China (early Late Cambrian) whereas the upper with the Proconodontus Zone of the Hwajeol Formation in Korea and North America, and the lower Proconodontus-Rotundoconus Zone in North China (middle to early-late Late Cambrian). However, it needs more refined study based on abundant conodonts for the precise determination of the lower boundary of the Machari Formation. The lowest ca. 23m interval of the formation is not considered here. Two new conodont species are proposed: Coelocerodontus kosangolensis n. sp. and Hertzina? n. sp.
