Judging from the graphs showing the relation between soil indices and depth, the Index Profiles, and the correlations between some of the soil indices in the data tested on Recent clayey soil samples in the area of Port of Tokyo, are found as follows: 1) Apparent change of facies and engineering properties in the Recent deposits, is recognized in the horizon between 15 m and 20 m below the sea level in Arakawa peil, which is correlated with limax phase of post-glacial transgression. 2) The Recent very soft clayey beds are affected considerably by many artificial factors such as land-reclaiming. 3) From some of the graphs showing correlation between soil indices, a difference of the diagenesis of clayey deposits can be recognized between Yurakucho clayey formation (Yc) and Nanagochi silty formation (Nau).
