Abstract

Four Tertiary basins are distributed on the eastern coast of the southern Korean Peninsula, that is, Bugpyeong, Yeonghae, Pohang and Yangnam basins from north to south. The Yangnam and Pohang basins are the largest ones and have been well studied on their stratigraphies, paleoenvironments and geologic ages, and their tectonic history is representative on the tectogenesis of the Tertiary basins of the southern Korean Peninsula. The geologic events occurred in the Yangnam and Pohang basins from the Early-Middle Eocene through the Middle Miocene suggest that the Yangnam and Pohang basins resulted from the volcanism and rifting caused by the uprising magma, that is, by the diapiric tectogenesis.
