Finer sediments, overlying higher terraces along the Ara River and the Tainai River flowing in the northern part of Niigata Prefecture, were divided into five units, namely black soil, brown loam, light brown loam, reddish brown loam and dark reddish brown loam in descending order. Five micro marker tephra horizons were defined in the eolian loam namely G1, G2, G3, G4 and G5. Volcanic glass shards of G1 and G2 correlate with the Asama-Kusatsu Tephra (AT: 15-1614C ka) and the Aira-Tn Tephra (As-K: 26-29 14C ka), respectively. Based on the geomorphologic configuration and the micro tephra horizons, the terraces in the middle reaches of Miomote River, Ara River, Tainai River and Kaji River were classified into five, ten, six and nine respectively. Accumulation terraces located in all rivers of the northern part of Niigata Prefecture namely Kumanobori Terrace, Ueno Terrace, Kurokawa I Terrace and Nakanakayama Terrace that formed just before the AT tephra in the last glacial stage. Erosion terraces formed after the last glacial stage were formed after the As-K tephra. Nakahara Terrace, Omi Terrace, Kurokawa II Terrace and Akatani III Terrace were considered to be formed at latest the early stage of Jomon Period, and Hashiba Terrace, Kurokawa III Terrace and Akatani Ⅳ Terrace were considered to be formed at latest the middle stage of Jomon Period by distribution of archeological sites.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "160737", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Fujihira, Shuichiro"}]}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟大学積雪地域災害研究センター"}]}, "item_7_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_7_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00183327", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "03877892", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "藤平, 秀一郎"}], "nameIdentifiers": [{"nameIdentifier": "160736", "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": "2019-08-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "26_101-114.pdf", "filesize": [{"value": "1.1 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1100000.0, "url": {"label": "26_101-114.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/27967/files/26_101-114.pdf"}, "version_id": "3ec5e00a-ffb2-40f4-8783-cd05d456530c"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "eolian deposit", "subitem_subject_scheme": "Other"}, {"subitem_subject": "marker tephra horizons", "subitem_subject_scheme": "Other"}, {"subitem_subject": "terrace classification", "subitem_subject_scheme": "Other"}, {"subitem_subject": "風成層", "subitem_subject_scheme": "Other"}, {"subitem_subject": "指標テフラ層準", "subitem_subject_scheme": "Other"}, {"subitem_subject": "段丘面区分", "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": "風成層に基づく新潟県北部,三面川・荒川・胎内川・加治川の河成段丘区分と編年", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "風成層に基づく新潟県北部,三面川・荒川・胎内川・加治川の河成段丘区分と編年"}, {"subitem_title": "風成層に基づく新潟県北部,三面川・荒川・胎内川・加治川の河成段丘区分と編年", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1557"], "permalink_uri": "http://hdl.handle.net/10191/39271", "pubdate": {"attribute_name": "公開日", "attribute_value": "2016-03-09"}, "publish_date": "2016-03-09", "publish_status": "0", "recid": "27967", "relation": {}, "relation_version_is_last": true, "title": ["風成層に基づく新潟県北部,三面川・荒川・胎内川・加治川の河成段丘区分と編年"], "weko_shared_id": null}
