Abstract

The ESR-signal intensity associated with the oxygen vacancy in the fine quartz and the clay mineral composition were examined, in order to investigate the influence of eolian dust on the parent materials in a fine-textured Brown Forest soil developed on the bedrock, Tertiary dacitic Pyroclastic rock, near the top of Mt. Horyu in Noto peninsula. The results were summarized as follows: The high values, more than 10 unit, in the ESR-signal intensity of fine quartz in this soil suggested that, large amount of the eolian dust brought from the Precambrian sediment area influenced severely on the parent materials in this soil, and this eloian dust had been brought from Precambrian sediments area by NW-monsoon during the Last Glacial Maxmum, MIS2 (24-11 thousand years ago). On the other hand, the autochtonous Terciary bedrock was also influenced slightly on the parent materials in this soil. Moreover, the influence of a small amount of the Tephra such as A-Th was also observed in this soil.
