초록

The central-western Korean Peninsula contains records of an Early Mesozoic collisional event related to the final amalgamation of the East Asian continent. Here, we present a renewed geologic map of the Deokjeok and Soya islands in the central-western Korean Peninsula and its explanatory note. Our geologic map was based on a detailed investigation of the northeastern area of both islands, which is characterized by a complex fault and shear zone system that accommodated the crustal deformation related to the Mesozoic post-collisional orogenic collapse and the subsequent structural inversion. We suggest future directions of study aiming at addressing issues regarding the deformational responses of crust to the Mesozoic tectonic transition and orogenic cycles.
