Abstract
The characteristics of grain size distributions of muddy surface sediments off southwest Japan are discussed. The results presented in this article are based on 300 textural analyses and 133 clay mineral analyses.
Muddy sediments are distributed on the continental shelf and continental slope-deep sea terraces. Judging from the characteristics of grain size distributions and compositions of clay minerals, muddy sediments on the continental shelf are distinguished from those on the continental slope-deep sea terraces. The grain size distributions of surface sediments of the deep sea terraces slightly differ from those of the turbidites.
