Aso-2, Aso-3, Aso-4およびアルカリ岩質テフラ層を年代基準として堆積速度を算出し,主要なテフラ層の年代を求め,酸素同位体比ステージとの対応について検討した.その結果,高野層コアは約160kaから約30kaのMIS6からMIS3に相当し,中期更新世末から後期更新世の広域テフラ層の標準層序を提供できることが明らかになった.", "subitem_description_type": "Abstract"}, {"subitem_description": "A 53.88m sediment core (TKN-2004) taken from the Takano Formation, Nagano Prefecture in central Japan, consists mostly of homo-genous clayey silt, including numerous beds of primary fallout tephra. On the basis of the stratigraphy, petrography, and chemistry of volcanic glass shards, hornblende, and orthopyroxene measured by microprobe (EDS) analyses, 15 tephra beds can be correlated to the Aso-2, Aso-3, Nanko-Ⅱ, Nanko-Ⅲ, SK, Tt-D, Ata, Aso-ABCD, On-Pm1, K-Tz, On-Kt, Aso-4, On-Ng, Tt-E, and BW1466 tephra beds in ascending order. Using the 4 time marker tephra bedsnamely, Aso-2 (146ka), Aso-3 (133ka), Aso-4 (88ka), and BW1466 (38.5ka)-as the controlling points, depositional ages of other 17 marker tephra beds in the TKN-2004 core can be calculated, postulating that sedimentation rate is constant between the controlling points. The ages of marker tephra beds in the TKN-2004 core estimated by this method are very consistent with the identification of the oxygen isotope stages based on the palynological study of the Takano Formation and the total organic carbon content profile of the TKN-2004 core. Consequently the TKN-2004 core sample can provide not only a high-resolution record of the climate from MIS 6 to MIS 3, but also the standard stratigraphy of the widespread tephra beds of the middle to upper Pleistocene in southwest to central Japan.", "subitem_description_type": "Abstract"}]}, "item_6_description_30": {"attribute_name": "資源タイプ（コンテンツの種類）", "attribute_value_mlt":
