Abstract

A careful literature review reveals that the Gyeonggi Massif in Korea extensively undergoes the collision-related metamorphism during the Triassic and thus represents a subduction complex with the South China affinity. The Triassic subduction complex is bounded by the Imjingang belt to the north and the Hongseong–Odesan belt to the south and can be well correlated with the Sulu–Dabie belts of China in the P–T–t paths. Therefore, the Gyeonggi Massif is a part of the South China Block, and the boundary between the North China Craton and the South China Block lies on the Imjingang belt. The Paleoproterozoic tectonic events in and around the Hongcheon area of the Gyeonggi Massif can be attributed to the accretion of the South China Block onto the Columbia supercontinent during the Paleoproterozoic. Such Paleoproterozoic tectonothermal events are well documented in the South China Block, in particular along its northern margin.
