The upper Triassic to lower Jurassic(?) Daedong Supergroup of Korea has been deposited syntectonically during the late stages of “Songnim” transcurrent tectonism. In the Daedong basins, the Jurassic Daebo tectonism resulted in heterogeneous deformation due to the reactivation of pre-existing large faults during two main phases of folding and high angle thrusting. During the first phase, the bounding faults of the Daedong basins have been reactivated as high angle imbricated thrusts associated with gentle folds that display northeast-southwest axial trends and are generally southeast facing. The second tectonic phase is a result of north-south-directed convergence. The axes of gentle second phase folds strike east-west on average and are overturned to the south. Major NE-SW faults were then reactivated as south-directed sinistral wrench thrusts. This tectonic episode likely occurred in the late Jurassic to early Cretaceous period, and finally generated half-grabens or pull-apart basins located along the margins of the Ogcheon belt. The so-called “Daebo granites” have intruded from late Triassic to late Jurassic times. The Daebo granites and Funatsu granites of the same age in the Hida belt (Japan), are likely to be generated in a post-collisional setting as a consequence of the late Permian to Triassic Akiyoshi orogeny of southwest Japan.
