The U-Oki and AT tephras have been detected from this moor, and the environmental changes for the past 30 kyr has been revealed. In the past 30 kyr, the Hatchodaira moor has three cycles of gravel layers, clay layers, and peat layers.However, the K-Ah tephra (7.3 cal ka BP) has been not found, and it is necessary to consider the succession of sedimentary records. In this study, sediment cores were collected from a total of seven locations, five sites from the moor (about 200 m range) and two sites in branch valley. The lower horizon could not be collected because it hits the gravel layer near 1 m from the surface. First, the facies of sediment cores were observed, and then X-ray imaging, digital color measurement, initial magnetic susceptibility measurement, elemental analysis (C, N, S), mud content measurement, major-element compositional analysis of volcanic glass, and AMS 14C dating were performed. A volcanic glass correlated with the AT was detected from around 85 cm in depth. The calibrated ages of about 13.4 cal ka BP are obtained from the plant fragments in the clay layer at the bottom. The U-Oki and K-Ah could not be found in this study. In the last cycle during the Holocene, there was sedimentation hiatus before and after K-Ah.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"琵琶湖に注ぐ安曇川水系の江賀谷川を水源付近の標高800～820メートルに位置する八丁平は、AT（約30cal ka BP）とU-Oki（約10.2cal ka BP）テフラが検出され、最近3万年間の環境変遷が復元されている。K-Ahテフラ（約7.3cal ka BP）は発見されておらず、堆積記録の推移を考慮する必要がある。本研究では、湿地（約200m範囲）から5か所、支谷の2か所の計7か所からコア試料を採取した。下部層準は、地表から100cm近くの砂礫層に当たるため採取できなかった。コア試料の層相観察、X線撮影、色調測定、初磁化率測定、元素分析（C、N、S）、含泥率測定、14C年代測定を行った。地点5の河岸露頭から約13.4cal ka BPの年代が得られた。深度85cm付近からATに対比される火山ガラス(再堆積)が検出されたが、U-OkiとK-Ahは見つからなかった。八丁平では最新の完新世サイクルではK-Ah前後の記録が残っていない可能性が高い。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18999/nagubc.7.36","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"名古屋大学宇宙地球環境研究所年代測定研究部","subitem_publisher_language":"ja"},{"subitem_publisher":"Division for Chronological Research, Institute for Space‒Earth Environmental Research, Nagoya University","subitem_publisher_language":"en"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"西川, 空","creatorNameLang":"ja"},{"creatorName":"Nishikawa, Ku","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"奥野, 充","creatorNameLang":"ja"},{"creatorName":"Okuno, Mitsuru","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"大下, 愛央","creatorNameLang":"ja"},{"creatorName":"Oshita, Mao","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"藤木, 利之","creatorNameLang":"ja"},{"creatorName":"Fujiki, Toshiyuki","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"中西, 利典","creatorNameLang":"ja"},{"creatorName":"Nakanishi, Toshimichi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"林田, 明","creatorNameLang":"ja"},{"creatorName":"Hayashida, Akira","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"鳥井, 真之","creatorNameLang":"ja"},{"creatorName":"Torii, Masayuki","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"洪, 完","creatorNameLang":"ja"},{"creatorName":"Hong, Wan","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-01-05"}],"displaytype":"detail","filename":"036-042_2022.pdf","filesize":[{"value":"3 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/2008745/files/036-042_2022.pdf"},"version_id":"a3472d9c-4513-4328-940b-5c22aadb41a6"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Hatchodaira moor","subitem_subject_scheme":"Other"},{"subitem_subject":"Holocene","subitem_subject_scheme":"Other"},{"subitem_subject":"Kikai-Akahoya (K-Ah) tephra","subitem_subject_scheme":"Other"},{"subitem_subject":"Ulleung-Oki (U-Oki) tephra","subitem_subject_scheme":"Other"},{"subitem_subject":"Aira-Tn (AT) tephra","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"京都北山, 八丁平湿原から採取したコア試料の層序と年代","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"京都北山, 八丁平湿原から採取したコア試料の層序と年代","subitem_title_language":"ja"}]},"item_type_id":"40001","owner":"17","path":["1703659440327"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-01-05"},"publish_date":"2024-01-05","publish_status":"0","recid":"2008745","relation_version_is_last":true,"title":["京都北山, 八丁平湿原から採取したコア試料の層序と年代"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2024-01-05T06:24:56.838935+00:00"}
