| Abstract | The microscopic observations of the recent soil horizons were conducted in Okayama, Japan (moderate climate). The several soil horizons, including two surface (epipedon) and three subsurface horizons, were recognized in the forest, poorly vegetated hill, and riverside around the Okayama University. The umbric epipedon can be segregated from the organic-rich subsurface horizons by the scattered organic materials in thin sections. The ochrich epipedon shows the sandy matrix without any cements and the illuviation of clay minerals. The subsurface horizons identified in the study area are as follows: albic, argillic, and cambic horizons. Each subsurface horizon shows the specific structures in thin sections. The albic horizon is characterized by the absence of the illuviation. The argillic horizon definitely shows the clayey matrix and the illuviation of clay minerals. The primary structures may be retained in the cambic horizon. The microscopic examination of the Miocene paleosols from the Ukan-cho, Okayama, was attempted. By comparing the recent soils, the cambic horizon and spodic horizon, which is characterized by the concentration of sesquioxides, are identified in the paleosols. This attempt suggests that the microscopic observations of the recent soils is a useful guide to understanding the paleosols |

| Abstract | Permian and Triassic molluscan fossils are found from Mitsu-area, Okayama City, Southwest Japan. Permian bivalve and gastropod fossils are collected from mudstones of the Upper Formation of the Maizuru Group. 4 species of bivalves (Nuculopsis? sp. ind., Leptodesma sp. ind., Streblopteria cf. eichwaldi, Posidonia sp. ind.) and 5 species of gastropods (Worthenia cf. corrugata, Callitomaria n. sp. cf. stanislavi, Apachella n. sp. ind., ??Eunemopsis like trochid, ??Yunnania sp.) are identified. Lower Triassic bivalve fossils are collected from sandstones of the Oono Formation. Neoschizodus cf. laevigatus and Bakevellia (Maizuria) kambei are identified. |

| Title Alternative | Toward Understanding of Regional Climate in East Asia around the Last Glacial Maximum with Attention to the Seasonal Cycle and Daily Meteorological Systems |

| Abstract | Regional climate system in East Asia shows the characteristic seasonal cycle affected by the Asian monsoon with various types of its sub-systems. The seasonal cycle there is also related greatly to behaviors of the frontal zones which are the boundaries of these sub-systems. Since the variation of global-scale environment such as the global warming influences on each monsoon sub-system in rather different manner, it is necessary to understand the joint effects of these subsystems, in order to predict the regional climate change in East Asia in the global warming. In such research, it would be also useful to examine the features in the ice age, as an opposite extreme situation against the global warming. Thus the present paper will discuss some viewpoints in investigating the regional climate in the Last Glacial Maximum with attention to the seasonal cycle and daily meteorological systems. |
