The Late Paleozoie （Late Carboniferous-Early Triassic） sediments are well developed in the Korean Peninsula, and called the Pyongan System. The Pyongan System from Late Carboniferous to Lower Triassic is distributed in the Pyongnan and Hyesan-Riwon Basins, and Rangrim Massif, and divided into Hongjom （ C2 ）, Ripsok （ C2 ）, Sadong （ C2-P1 ）, Kobangsan and Rokam （Taezhawon） （P2-T1） sequences.
