Quaternary meandering evolution and architecture of a point bar in the Mun River on the sandstone-dominated Khorat Plateau from northeastern Thailand

The Mun River, the main right bank tributary of the Mekong River, meanders and flows eastwards across the flat and sand-dominated low-lying plain of the Khorat Plateau, northeastern Thailand. The Mun River expresses its evolution with a spectacular trace of its meander landforms on the floodplain surface. This paper reveals (for the first time) the three-dimensional shallow subsurface sedimentary architecture inside a part of a sandy point bar...
