A new Late Proterozoic stratum in South Korea

The Myeonsan Formation, the lowermost strata of the lower Paleozoic sequence, has basal conglomerate, which consists mostly of orthoquartzite and granitic gneiss clasts. The latter was derived from the basement rock (the Taebaeksan Gneiss Complex) underlying the Myeonsan Formation. However, a Precambrian sedimentary sequence, which is supposed to have supplied orthoquartzite clasts, has not been reported in South Korea. This study reports a newly definable Proterozoic stratum, less than 10 cm thick, formerly known as the lowermost part of the Myeonsan Formation. It is different from the lithology of the Myeonsan Formation, but is same in petrographical and geochemical characteristics to orthoquartzite clasts in basal conglomerate of the Myeonsan Formation. This stratum is interpreted to have been a source rock of orthoquartzite clasts to the lower Paleozoic basin. It is interpreted that the orthoquartzite sequence had been deposited in the Late Proterozoic, which is correlatable with the Guhyeon System in North Korea.
