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-\u2161, Nanko-\u2162, 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":"\u8cc7\u6e90\u30bf\u30a4\u30d7\uff08\u30b3\u30f3\u30c6\u30f3\u30c4\u306e\u7a2e\u985e\uff09","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_6_description_5":{"attribute_name":"\u5f15\u7528","attribute_value_mlt":[{"subitem_description":"\u7b2c\u56db\u7d00\u7814\u7a76.
