The sediment volume of soil clays separated from Gray Lowland Soils and Red and Yellow Soils was found to be related to the specific surface area, increasing exponentially (Na-clays) or linearly (Ca-clays) with increasing specific surface area. Sodium-saturated smectitic clays with higher specific surface area revealed a greater sediment volume compared to clays dominant in other clay minerals. The correlation between the sediment volume of Na-clays and specific surface area was good for the clays of Gray Lowland Soils but not so good for those of Red and Yellow Soils. This somewhat poor correlation for the clays of Red and Yellow Soils was thought to be due to a difference in the parameters related to particle shape and size.
