There are two main tectonic events in Korean Peninsula in Middle Paleozoic-Early Mesozoic, that are the activity of Limjingang belt in middle Korean Peninsula in Middle Paleozoic and the collision event of Domangang orogenic belt (Hambuk Masiff) in the northern part of Korean Peninsula in Late Paleozoic-Early Mesozoic.
The research on the characteristics of strata, fossils and structure shows Limjingang belt formed in Late Silurian-Early Devonian, and ended in Songlin Stage of Triassic in Mesozoic. Based on the petrological and chronological data of sedimentary strata and magmatic rocks of Hambuk massif, it is considered that domangang orogenic belt was formed during Permian-Trassic. The studies of geophysics and earthquake in the Yellow Sea and geotectonic and sedimentary strata show that Sulu high-pressure metamorphic belt not extended to Limjingang belt, but moved to the south of Cheju-do by the dextral fracture which north-south trending running across Korean West Sea. The study of geological characteristics in Hambuk massif and Susengchen fault zone show that Hambuk massif is probably connected with Jiamusi massif and Susengchen fault zone is probably connected withMudanjiang fault zone.
