The gouges were examined using X-ray powder diffraction analysis, sequential selective extraction tests, and color measurements. Results show that the aftershock-area gouge is mainly composed of illite and chlorite, while the non-aftershock-area gouge is mainly composed of halloysite. Iron in the aftershock-area gouge is mainly contained in illite, while in the non-aftershock-area gouge, it is mainly in the form of amorphous and crystalline iron oxide. Results of color measurements (L∗a∗b∗ color space) show that differences in L∗ values represent differences in the presence/absence of illite and halloysite, negative a∗ values from the aftershock-area gouge represent the presence of chlorite, and positive a∗ values from the non-aftershock-area gouge represent the presence of crystalline iron oxide. These results indicate that mineralogical and geochemical characteristics can clearly distinguish fault gouges in aftershock and non-aftershock areas of the 2000 Tottori-ken Seibu earthquake, and that color measurements can be an effective and simple proxy method for the screening of gouges that require further analysis in the field.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"環日本海域環境研究センター","subitem_description_type":"Other"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本地質学会 = Geological 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":"10.5575/geosoc.2012.0019","subitem_relation_type_select":"DOI"}}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.geosociety.jp/","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.jstage.jst.go.jp/browse/geosoc","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright © 日本地質学会 Geological Society of Japan"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00141768","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0016-7630","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":"間中, 光雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"福士, 圭介"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"宮下, 由香里"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"伊藤, 順一"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"渡部, 芳夫"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"小林, 健太"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"亀井, 淳志"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-05"}],"displaytype":"detail","filename":"SC-PR-FUKUSHIK-459.pdf","filesize":[{"value":"6.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SC-PR-FUKUSHIK-459.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/29328/files/SC-PR-FUKUSHIK-459.pdf"},"version_id":"5a4ba92f-5122-4655-98fa-05082a732793"}]},"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":"2000年鳥取県西部地震の余震域と非余震域に分布する断層ガウジの比較","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"2000年鳥取県西部地震の余震域と非余震域に分布する断層ガウジの比較"},{"subitem_title":"Comparison of fault gouges in the aftershock area and the non aftershock area of the 2000 Tottori-ken Seibu earthquake","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["1981"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-05"},"publish_date":"2017-10-05","publish_status":"0","recid":"29328","relation_version_is_last":true,"title":["2000年鳥取県西部地震の余震域と非余震域に分布する断層ガウジの比較"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-27T20:37:15.423591+00:00"}
