This geological fold accompanied by a fault is at a coastal cliff in Baengnyeongdo Island. The coastal cliff faces the Yongteurim Rock, located at about 300m west from the harbor of Jangchon. The formation extends close to 50m in height and 80cm in length. The fold and fault were created as a result of the deformation of the Jangchon group in the Precambrian Baengnyeong supergorup, widespread in Baengnyeongdo Island and its vicinity, caused by crustal movement that occurred between the late Paleozoic and early Mesozoic Era. The fold and fault were formed deep in the earth, under horizontal pressure causing metamorphism and deformation and were subsequently uplifted slowly through weathering and erosion of the earth’s crust, to attain their current appearance. Folds and faults of such large size that are, furthermore, clearly exposed like these ones are quite rare. They promise to provide valuable clues for understanding the history of crustal development in the Korean peninsula and are expected to make this area an important leaning destination for youth as well as a nature tourism destination.
