The Triassic period has been covered by sea, is subdivided in the namely Sao Khua Formation in four formations. This time occurred as Siamotyrannus isanensis as Phuwiangosaurus sirindhornae, is.

Acrisols Acrisols were described for the Petchbun Mountains. The upper sections of the topsoils are sandy-loamy clearly higher clay contents. Cambisols Cambisols were described for karst hills for slopes of limestone. The bottom of this layer were pisolithes and several gravel pieces. The upper section be recognized whereas the deeper-reaching exposures.
Sometimes large grikes be recognized in ground humps and the limestones. Pisolithic Plinthosols developed from fluvial deposits. The undelying parent material revealed again low radioelement signatures. Leptosols Leptosols are widespread in the area of the inselbergs. Solonchaks Solonchaks occur in the area of the Maha Sarakham Formation. Solonchaks derived in Khon Kaen province from the Maha Sarakham Formation.
