The Early Cretaceous Phra Wihan Formation is the second lowest member of the Mesozoic Korat Group which outcrops in Northeast Thailand. Comprises fine- to coarse-grained sheet and channelled sandstone beds and rarer variegated siltstone and mudstone. Intermittent conglomerate beds. Deposited in a fluvial environment dominated by high-energy, shallow braided rivers with subordinate lower energy meandering river systems and associated flood plains. The Phra Wihan Formation is considered to be Berriasian-Barremian in age based on recent palynology evidence.
