The Earth's orbital variations, reflected in Plio-Pleistocene ice volume (sea-level), were recorded in the turbidite sequence of the Kazusa Group in the Boso Peninsula, Japan. Vertical changes in layer thickness reflect the orbital eccentricity, obliquity, and precessional cycles, so-called "Milankovitch cycles." Turbudite deposition in submarine fans activated during the low-stand in sea level, the glacial period, and this period corresponds to low obliquity, conversely, a mud dominant part formed in the period of high sea level correspond to the increasing stage of eccentricity.
