| 摘 要： | 古生代中期─中生代早期朝鲜半岛发生了两次主要构造事件, 即古生代中期朝鲜半岛中部临津江构造带的活动和古生代晚期-中生代早期朝鲜半岛北部豆满江造山带(咸北地块) 的碰撞拼接事件。临津江带的地层、化石和构造等特征研究表明临津江带形成于志留纪末-泥盆纪初, 结束于中生代三叠纪松林期; 根据咸北地块沉积地层的岩浆岩岩石学、年代学资料, 认为豆满江造山带的碰撞拼接时期可能是二叠纪-三叠纪。黄海地球物理、地震研究, 朝鲜半岛大地构造和沉积盖层研究结果表明苏2鲁高压变质带没有延伸到临津江带, 而是被近南北向纵贯朝鲜西海的断裂右行错移到了济洲岛以南; 咸北地块和输城川断裂带的地质特征研究表明, 咸北地块可能与佳木斯地块相连接, 输城川断裂带可能与牡丹江断裂带相连接。

| Abstract: | 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. |
