Ten oriented cores were collected from the uppermost fine-grained vitric ash portion at one locality, and stepwise alternating-field and thermal demagnetizations were performed for 20 cylindrical specimens in order to isolate remanent magnetization components. More than half of the specimens had a single magnetic component with a northerly and down direction close to the present geomagnetic field direction (i.e., normal polarity). However, six samples, which also provided a normal polarity linear component, displayed a directional change along a great circle during stepwise demagnetization, indicating the presence of another higher coercivity/unblocking temperature component. Application of the great circle method disclosed the component with a SSW and up direction (i.e., reversed polarity). A previous study has reported that the PM tephra bed is normally magnetized; however, the author interprets that the normal polarity direction is most likely a secondary component and the primary magnetization has reversed polarity. This interpretation is concordant with tephrostratigraphic investigations suggesting that the PM tephra bed is correlated to the reversely magnetized tephras found in several areas of central Japan.","subitem_description_type":"Abstract"}]},"item_3_link_3":{"attribute_name":"研究者総覧へのリンク","attribute_value_mlt":[{"subitem_link_text":"星, 博幸","subitem_link_url":"https://souran.aichi-edu.ac.jp/teachers/3b00c17b43be8186.html"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"愛知教育大学"}]},"item_3_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12466167","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1884-5169","subitem_source_identifier_type":"ISSN"}]},"item_3_text_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"subitem_text_value":"愛知教育大学研究報告, 自然科学編. 2012, 61, p. 49-53."}]},"item_3_text_26":{"attribute_name":"著者別名","attribute_value_mlt":[{"subitem_text_value":"ホシ, ヒロユキ"}]},"item_3_text_4":{"attribute_name":"著者(別言語)","attribute_value_mlt":[{"subitem_text_value":"Hoshi, Hiroyuki"}]},"item_3_version_type_14":{"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":"星, 博幸"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-03-27"}],"displaytype":"detail","filename":"kenshi614953.pdf","filesize":[{"value":"545.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kenshi614953.pdf","url":"https://aue.repo.nii.ac.jp/record/610/files/kenshi614953.pdf"},"version_id":"013e1e28-d6e2-4683-a2a8-b0e93998f918"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"PMテフラ","subitem_subject_scheme":"Other"},{"subitem_subject":"PM tephra","subitem_subject_scheme":"Other"},{"subitem_subject":"火山灰層","subitem_subject_scheme":"Other"},{"subitem_subject":"volcanic ash bed","subitem_subject_scheme":"Other"},{"subitem_subject":"鮮新世","subitem_subject_scheme":"Other"},{"subitem_subject":"Pliocene","subitem_subject_scheme":"Other"},{"subitem_subject":"古地磁気","subitem_subject_scheme":"Other"},{"subitem_subject":"paleomagnetism","subitem_subject_scheme":"Other"},{"subitem_subject":"広域対比","subitem_subject_scheme":"Other"},{"subitem_subject":"regional correlation","subitem_subject_scheme":"Other"},{"subitem_subject":"氷見地域","subitem_subject_scheme":"Other"},{"subitem_subject":"Himi area","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":"富山県氷見地域に分布するPMテフラ層の古地磁気方位","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"富山県氷見地域に分布するPMテフラ層の古地磁気方位"}]},"item_type_id":"3","owner":"3","path":["79"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-03-29"},"publish_date":"2012-03-29","publish_status":"0","recid":"610","relation_version_is_last":true,"title":["富山県氷見地域に分布するPMテフラ層の古地磁気方位"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T16:19:04.727452+00:00"}
