The K-T boundary sediments contain relatively high Ir concentrations suggesting an asteroid struck the Earth and caused mass extinctions at the end of the Cretaceous. Foraminifera are totally absent in the grayish black clay. Mineralogical investigations of the claystone have been carried out by the use of X-ray powder diffraction, high resolution electron microscope, energy dispersive spectrometer and heavy-iron Rutherford scattering. Singularity of clay minerals of a continuous stratigraphic section spanning the K-T boundary reveals that the spherical interstratified clay in < 2μm fraction are largely decomposed. The spherical clay shows characteristic stacking disorder of 14Å, 10Å, 7Å phase, which is suggested to be heating eventsin the K-T boundary.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学理工研究域地球社会基盤学系","subitem_description_type":"Other"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00061654","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本粘土学会 The Clay Science Society of Japan"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.11362/jcssjnendokagaku1961.32.86","subitem_relation_type_select":"DOI"}}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://www.jstage.jst.go.jp/browse/jcssjnendokagaku/-char/ja"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.jstage.jst.go.jp/browse/jcssjnendokagaku/-char/ja","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.cssj2.org/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.cssj2.org/","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright © 日本粘土学会 The Clay Science Society of Japan"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA1155672X","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0470-6455","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"2186-3563","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"attribute_name":"著者版フラグ","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":"田崎, 和江"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"荒谷, 美智"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"矢野 , 倉実"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"海保, 邦夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"野田, 修司"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-07-19"}],"displaytype":"detail","filename":"SC-PR-TAZAKI-K-86.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-TAZAKI-K-86.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/55379/files/SC-PR-TAZAKI-K-86.pdf"},"version_id":"036ebb49-0ce3-48ce-87f5-42331f041356"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"K-T境界における粘土鉱物の特異性とイリジウム","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"K-T境界における粘土鉱物の特異性とイリジウム"},{"subitem_title":"Singularity of Clay Minerals and Iridium Concentration at Cretaceous-Tertiary (K-T) Boundary","subitem_title_language":"en"}]},"item_type_id":"4","owner":"18","path":["937"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-07-19"},"publish_date":"2021-07-19","publish_status":"0","recid":"55379","relation_version_is_last":true,"title":["K-T境界における粘土鉱物の特異性とイリジウム"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T15:10:51.070915+00:00"}
