Previous dating studies have focused on 14C dating of carbon-bearing mud, gastropod shells and water plants and the results show a large amount of scatter for different heights above the lake. This scatter can be partly explained by the mix of extraneous detrital carbonaceous material in the mud and plant material. Measurements of water from restricted basins and the open lake show significant differences in 14C/12C ratios, and samples formed in equilibrium with restricted basins will have a different reservoir effect to those formed in equilibrium with the main body of the Lake. Sampling of tufa deposited from lake water is largely unaffected by detrital material and is potentially a good material to estimate the age of shorelines. However, tufa may also form much later than the lake shoreline at some depth in the sedimentary pile and may be formed in equilibrium with water containing old C. These problems can be minimized by using samples that are attached firmly to rock substrate and in regions where the overall dip of the shoreline is steep and formation of restricted lagoons is unlikely. Preliminary results using this sampling strategy give an age of around 6,000 years ago for a height of 11m. This is in very good agreement with two OSL dates for shorelines and the associate heights reported in the literature.", "subitem_description_language": "en", "subitem_description_type": "Abstract"},

"ナムツォ湖周辺に分布する古段丘の年大決定はチベット高原の中部地殻の有効粘性を推定するための研究プロジェクトにおいて必要不可欠である。従来の年代研究は炭素14の年代法を用いて巻き貝・泥・水生植物の試料に着目してきたが、推定年代は大きくばらつき、湖水面からの高さと有意な相関を示さない。泥と水生植物破片測定値のばらつく原因として外来砕屑性の炭質物の混在があげられる。また、湖の主要な水域から隔離された潟の水は湖の本水域の組成と大きく異なる14C/12C比を示し、これらの水体と平衡に形成した試料はそれぞれの炭素同位体比を反映し、リサーバー効果は大きく変動する可能性がある。湖水から沈殿したトゥファは砕屑性の混入物の問題は少なく、段丘の年代を推定するのに適しているものである可能性が高い。ただし、トゥファは段丘形成後、堆積物の中で成長するものもあり、このような二次的に形成したものは段丘の形成年代を示さない。これらの段丘の形成年代決定の不確定要素を最小限になるように基盤岩に固着したものを選別し、また湖底傾斜が大きく、潟など隔離された水域の形成は考えにくい地域で試料を採取することは有効である。この試料採取作戦を適応した年代測定結果、湖水面から約11mの高さにある古段丘の年代は約6.5ka であることは明らかになった。この高さと年代は2つの既存のOSL段丘年代と高さと調和的である。", "subitem_description_language": "ja", "subitem_description_type": "Abstract"}]}, "item_9_description_5": {"attribute_name": "内容記述",
