Three palynological researches were reported in this paper: they are (1) the study on the typical late Tertiary system developed around Kanazawa and in the Aikawa-Sawane route in Sado Island; (2) the pollen analysis of the Diluvial deposits developed extensively at some localities of the district, (a) early Diluvial terrace deposits in Kanazawa, (b) late Diluvial marine terrace deposits around Hiradoko, (c) late Diluvial Okuhara marine terrace deposits near Nanao; (3) the investigation on the Alluvial deposits developed beneath the Imizu plain, Toyama Prefecture.A summary of the palynological studies on the late Tertiary deposits is shown on Fig. 1.The geologic profile of Hiradoko terrace (Fig. 2B), change of sea-level (Fig. 2A), several paleogeographic maps (Fig. 3, left), a series of schematic profiles (Fig. 3, center) and pollen assemblages in several stages of Hiradoko age (Riss-Würm interglacial age) (Fig. 3, right) will help for understanding the climatic change through Hiradoko age.A summary of the palynological studies on the late Pleistocene Okuhara formation and Alluvial deposits is shown in Figs. 4 and 5 respectively.
