Geochang intramontane basin is formed in Deokyu-Gaya mountains. There are Piedmont,flat ridge, terrace, river flood plain in Geochang-Basin. Sediments are found in end partsin terraces. The purpose of this study is the analysis of those sediments in order to explain the transport agency. For this aim were achieved field work, sieving, microscopical observation of sand particles and sand slide, reading of clay fractions through X-ray diffraction method.Terrace sediments are originated from bed rocks in the vicinity areas. Characteristics of sediments show fluvial of creek or rivers and transport distance is not so long. The changes of sedimentation faces are derived from flow courses and two terraces are classified in this basin but the milieu of the sedimentation is similar to each other in two terrace systems.
