Grain-size analysis was held on the sediments (sand-size sediments in paticular) sampled in Paleo-Tokyo Bay area with a settling tube. The results indicate the importance of sedimentary processes in each environment. A shore-normal sorting trends and shifts is the skewness are interpreted as parameters controled by sedimentary mechanism: how carried, how deposited, and how much reworked. The mineralogical maturity and textural maturity are related correlatively.
