The thickness of the alluvium beneath the Echigo Plain reaches a maximum of 140m. The alluvium of the Echigo Plain is very thick compared to other alluvial plains in Japan probably because the Niigata area is located in an active tectonic zone in the back-arc side of the Japanese Islands and thus the Plain has continually subsided throughout the Holocene. The alluvium in the Niigata area shows high subsidence rates and provides a detailed record of glacio-eustatic changes of sea level in the Holocene, relative sea level changes due to tectonic movements, and changes in depositional system. Especially, the alluvium after Holocene maximum transgression provides important indications of the impact of tectonic movements on subsidence. On each core sample of the Ajikata, Yoroigata, Matsushima, Yamanoshita and Shimoyama in the Echigo Plain, this study examined the index volcanic ash and depositional facies. As this result, the transition of the sedimentary environment of each core was clarified, and the presence of the volcanic ash about 5000 BP of the Numazawa volcano origin also became clear. By the depositional facies analysis in these core and setting of the time base, it indicates that the plain is subsided at 13～19m during about 5000 year. This is the clear evidence that shows the subsiding of the alluvium.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "160816", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Urabe, Atsushi"}]}, {"nameIdentifiers": [{"nameIdentifier": "160817", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Takahama, Nobuyuki"}]}]}, "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": "ト部, 厚志"}], "nameIdentifiers": [{"nameIdentifier": "160814", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "高濱, 信行"}], "nameIdentifiers": [{"nameIdentifier": "160815", "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": "24_63-76.pdf", "filesize": [{"value": "833.0 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 833000.0, "url": {"label": "24_63-76.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/27982/files/24_63-76.pdf"}, "version_id": "7b39e0ea-5d22-44fb-be0c-b4b2a10f6105"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Subsidence of alluvium", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Numazawa volcanic ash", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Holocene maximum transgression", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Echigo Plain", "subitem_subject_scheme": "Other"}, {"subitem_subject": "沖積層の沈降", "subitem_subject_scheme": "Other"}, {"subitem_subject": "沼沢火山灰", "subitem_subject_scheme": "Other"}, {"subitem_subject": "縄文海進", "subitem_subject_scheme": "Other"}, {"subitem_subject": "越後平野", "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": "越後平野における沖積層の沈降と約5,000年前の指標火山灰", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "越後平野における沖積層の沈降と約5,000年前の指標火山灰"}, {"subitem_title": "越後平野における沖積層の沈降と約5,000年前の指標火山灰", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1559"], "permalink_uri": "http://hdl.handle.net/10191/39248", "pubdate": {"attribute_name": "公開日", "attribute_value": "2016-03-08"}, "publish_date": "2016-03-08", "publish_status": "0", "recid": "27982", "relation": {}, "relation_version_is_last": true, "title": ["越後平野における沖積層の沈降と約5,000年前の指標火山灰"], "weko_shared_id": null}
