However, their formation processes and origin still remain in need of research. So in order to determine dates of a massive ground ice body in Mackenzie Delta, AMS radiocarbon dating has been carried out on the sediment and ice cores from it, and on sediment and shell samples overlying it. Radiocarbon dates for the muddy sediments from 21.0m ice core are 14270,17000 and 17070 yrBP at 10.2,20.2 and 20.5m in depth, respectively. Date for sand at 21.0m in depth is 25400yrBP. On the other hand, dates for the frozen clays ovealying the ice body are \u003e26600yrBP and the shallow one predates the deeper one. These facts show that the sediment overlying the ice body consists of re-worked till, that this re-worked till overlay this ice body at that time. Radiocarbon dates for twigs in the sediment overlying the ice body are 7520yrBP in the active layer and 9880yrBP in the permafrost layer. From these dates and those for root and peat in the re-worked till and also shell found on this till, it is seen that the till had re-worked in 8600〜8900yrBP. These dates agree with those for wood fragments in the re-worked till of Ibyuk Pingo near this ground massive ice body. Accordingly, this massive ice body is not of segregated ice origin but of buried ice origin. Taking into consideration the variations in the vertical profiles of oxygen isotopes and both number and kind of pollen in the ice core, this ice body is considered to be the relic glacier ice of the Laurentide ice sheet.", "subitem_description_type": "Abstract"}]}, "item_9_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/sumrua.3.84", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "名古屋大学年代測定資料研究センター 天然放射性元素測定小委員会"}]}, "item_9_relation_43": {"attribute_name": "異版である", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://ci.nii.ac.jp/naid/110000475799/", "subitem_relation_type_select": "URI"}}]}, "item_9_rights_12": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "名古屋大学年代測定資料研究センター 天然放射性元素測定小委員会"}, {"subitem_rights": "本文データは学協会の許諾に基づきCiNiiから複製したものである"}]}, "item_9_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_9_text_14": {"attribute_name": "フォーマット", "attribute_value_mlt": [{"subitem_text_value": "application/pdf"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "加藤, 喜久雄"}], "nameIdentifiers": [{"nameIdentifier": "79528", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kato, Kikuo"}], "nameIdentifiers": [{"nameIdentifier": "79529", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "KJ00000187534.pdf", "filesize": [{"value": "512.0 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 512000.0, "url": {"label": "KJ00000187534.pdf", "url": "https://nagoya.repo.nii.ac.jp/record/11331/files/KJ00000187534.pdf"}, "version_id": "e81060a6-f121-4353-97e6-b20c6ec361f6"}]}, "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": "北極域カナダ・マッケンジー・デルタの地下集塊氷の生成年代と生成過程", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "北極域カナダ・マッケンジー・デルタの地下集塊氷の生成年代と生成過程"}]}, "item_type_id": "9", "owner": "1", "path": ["1221"], "permalink_uri": "https://doi.org/10.18999/sumrua.3.84", "pubdate": {"attribute_name": "公開日", "attribute_value": "2010-04-27"}, "publish_date": "2010-04-27", "publish_status": "0", "recid": "11331", "relation": {}, "relation_version_is_last": true, "title": ["北極域カナダ・マッケンジー・デルタの地下集塊氷の生成年代と生成過程"], "weko_shared_id": null}
