A total of 23 specimens were collected from the trench sections of the archaeological area, around Yongseong-ri, Buryang-myeon, Gimje. The diatoms identified to 61 species belonging to 32 genera and species diversity and abundance were very few. Three diatom assemblage zones were set up according to the vertical assemblage of each horizons, the absolute abundance of diatoms and the distribution of indicator species. In diatom assemblage zone I, marine species was mainly occurred. Because the marine species is not reported in study of the adjacent area, it is valuable data on sea-water inflow. In diatom assemblage zone II, the yield of brackish and freshwater species are abundant, indicating that the brackish water environment was caused by the influx of freshwater. In diatom assemblage zone III, the yield of freshwater species is high and species of genus Eunotia are mainly occurred. It is considered that they are deposited in wet soil environment where freshwater inflows occasionally.
