In this paper, the consolidation test was performed for argillaceous rocks sampled from every formation of Kazusa Group (belonging in Pliocene or Pleistocene). The results obtained by investigation of the consolidation characteristics and consideration of the relation between this characteristics and geological classification are summarized as follows : (1) The correlation between stratigraphy and consolidation yield stress can be confirmed by considering initial void ratio e_0 (2) As initial void ratio e_0 is larger, the effect of aging by cementation is more remarkable in same member or formation. And, the e -log p curves approach gradually each other in normal consolidation region in excess of yield point regardless of difference of initial void ratio e_0 (3) In every formation of Kazusa Group, on extended condition that samples are consolidated to 0.1-0.2 in void ratio or to 2000-3000 kgf/cm^2 in stress, it is considered that the e - log p curves tend to draw near each other applying extrapolation method.
