- Stratigraphic distribution of the fossil diatom <i>Lancineis rectilatus</i> in the Lower Pleistocene Kazusa Group in the Tama Hills, central Japan, and its geological and palaeontological significance
抄録
Lancineis rectilatus is a fossil diatom that appeared in the middle Early Pleistocene and disappeared in the early Middle Pleistocene in the shallow marine sediments of the central Kanto Plain, central Japan. In this study, diatom assemblages of the Oyamada to Iimuro Formations of the Lower Pleistocene Kazusa Group exposed along the Tama River and in Honmoku, Yokohama City, are investigated to clarify the stratigraphic relationship between the tephra beds and the occurrence of L. rectilatus in the Tama Hills. The Oyamada to Inagi Formation section is dominated by coastal shallow-marine diatoms. The Ozenji to Iimuro Formation of the Yokohama-Honmoku section is dominated by pelagic diatoms. L. rectilatus is identified from above the NK tephra layer of the Iimuro Formation. The NK tephra in the Tama Hills and the Kd12 Type tephra in the central Kanto Plain are possibly correlative.
