 note = {application/pdf, The Himi Group, of which flora and fauna have been subjected to intensive studies for many years, has been analyzed for sedimentological and microfossil contents. The Himi Group was not clearly defined by previous workers and many discrepancies were present in its definition. A detailed study of fauna and lithofacies, particularly study of tephra, has made it possible to redefine this group. Thus, the Himi Group is here redescribed to include a unit (the Inazumi Formation) which has so far been excluded from this group. Many geological sections from widely separated areas were studied and a biostratigraphic succession of the Himi Group is established on the basis of stratigraphic distribution of planktonic foraminifera and calcareous nannoplankton. The Pliocene/Pleistocene boundary in Hokuriku Province is also indicated. Beside these, Recent foraminifera from the bottom sediments of Toyama Bay are also studied. The fauna comprises four depth assemblages. These assemblages may be useful in estimating probable depth of depostion for areas having a similar faunal content. Statistical analyses of benthonic fauna of the Himi Group were made by utilizing cluster and factor analyses, and from these analyses the fauna is classified into six assemblages. The sedimentological analysis together with the faunal analysis was used to reconstruct the character of paleo-water masses., 紀要類(bulletin), 8143829 bytes},
