| 内容記述 | Pumoyum Co is fresh water lake formed by fault action, and located in the southeastern Tibetan plateau (28°34'N, 90°24'E, altitude: ～5030 m asl, lake surface area: 281 km2, maximum water depth: ～65 m). Lake Pumoyum Co has at least 40 m sedimentary sequence, which is believed to cover the latest Quatemary. A first continuous sediment core (PY104PC, core length; 4 m) was taken from the eastern part of Pumoyum Co in the April 2001 for the reconstruction of climatic changes on the area. For Lake Pumoyum Co, preliminary results for ^<14>C ages of plant residues in a sediment core have been reported by Watanabe et al (2008). In the previous ^<14>C chronology, estimation of changes in the sources of plant residues and reservoir effects were insufficient. Therefore, major c1imate boundary layers, such as Bølling- Allerød warm phase, have not been determined. In 2006, a new continuous sediment core (PY608W-PC， core length: 3.9m) was obtained using a piston corer from Lake Pumoyum Co (28°33'14"N; 90°28'17''E, at a water depth of 50 m). In this study, fine plant residues in the PY608W-PC core were concentrated by wet-sieving (opening, 125μm) and were picked up in order to eliminate the effect of old carbon. ^<14>C dating of the plant residues from the PY608WPC shows that the sediment core contains a continuous record, over the past 19 cal ka BP. The layer with transition into Bølling-Allerød (BA) warm phase from the last glacial period (～15 cal ka BP) was consistent with the obvious lithologic boundary (sudden disappearance for the macrophyte remains in sediment layer) | |||||
