Lake Yamanaka (surface area 6.89km²; maximun depth 14.3m; mean depth 9.4m; altitude above sea level 978m) is one of the Fuji Five Lakes and located at the northern foot of Mt.Fuji. Although this lake had been considered formed by the lava flow from Mt.Fuji about 1850 years ago, results of this research suggested that the formation age more old stage on account of the presence of planktonic diatoms mentioned below. The borehole core sample has mainly consists of unconsolidated silts and scoria fall deposits associated with sandstone layers. According to the composition of diatoms contained in silts, the geohistory of this lake was divided into 4 periods;i.e., 1) The 1'st swamp or river period (11.4-9.2m borehole core in depth); Epiphytic or benthic diatomes such as Flagiralia spp. or Epithemia sp. were dominant in these samples. 2) The 1'st lake period(9.2-6.0m borehole core in depth): Planktonic diatoms such as Aulacoseira sp. or Cyclotella sp. were dominant in these samples. 3) The 2'nd swamp or very shallow lake period(6.0-2.5m borehole core in depth): Epiphytic or benthic diatoms became dominant again. 4) The 2'nd lake period (2.5m-surface borehole core): Planktonic diatoms were dominant again.","subitem_description_type":"Abstract"}]},"item_10_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_10_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"信州大学山地水環境教育研究センター研究報告 2: 105-110(2004)","subitem_description_type":"Other"}]},"item_10_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"信州大学山地水環境教育研究センター"}]},"item_10_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1348-7612","subitem_source_identifier_type":"ISSN"}]},"item_10_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11887942","subitem_source_identifier_type":"NCID"}]},"item_1627890569677":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"YOSHIZAWA,  Kazuya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KOSHIMIZU,  Satoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"UCHIYAMA,  Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-28"}],"displaytype":"detail","filename":"InlandWater02-20.pdf","filesize":[{"value":"708.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"InlandWater02-20.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/16362/files/InlandWater02-20.pdf"},"version_id":"c9787dd5-0f1a-4f57-bd60-e0e35c44bc5e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Lake Yamanaka","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"diatom assemblage","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"borehole core","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"lake history","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Environmental change based on diatom assemblages from Lake Yamanaka at the northern foot of Mt, Fuji, Central Japan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Environmental change based on diatom assemblages from Lake Yamanaka at the northern foot of Mt, Fuji, Central Japan","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["1606"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-02-27"},"publish_date":"2009-02-27","publish_status":"0","recid":"16362","relation_version_is_last":true,"title":["Environmental change based on diatom assemblages from Lake Yamanaka at the northern foot of Mt, Fuji, Central Japan"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-09T01:25:56.376342+00:00"}
