The NRMs with 1.38 to 22.1×(10)^<-7>Am^2/kg in intensity were very stable against AF demagnetization at least up to 50mT. The magnetic layers consisted with the dirt-ice layers recognized by the naked eye, but magnetizations in the clear-ice were weak for any significant measurements. The uniform NRM directions were obtained in the dirt-ice layers with upward directions. Those of the oriented 2 samples (A, E) were almost parallel to the present geomagnetic field direction in situ. So, a possible mechanism is rearrangement of the magnetic grains adjusting the NRM directions to the geomagnetic field direction due to partial melting of the ice around the grains by the solar radiation.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00008672","subitem_identifier_reg_type":"JaLC"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00181831","subitem_source_identifier_type":"NCID"}]},"item_1_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00857289","subitem_source_identifier_type":"ISSN"}]},"item_1_subject_21":{"attribute_name":"国際十進分類法","attribute_value_mlt":[{"subitem_subject":"551.32","subitem_subject_scheme":"UDC"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"国立極地研究所"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1990-07-01"}],"displaytype":"detail","filename":"KJ00000139937.pdf","filesize":[{"value":"304.2 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000139937","url":"https://nipr.repo.nii.ac.jp/record/8672/files/KJ00000139937.pdf"},"version_id":"97f3b8d9-d183-4932-a5c6-c57fd48f4c19"}]},"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":"東南極大陸の裸氷域から採集された火山灰を含む氷層の自然残留磁気","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"東南極大陸の裸氷域から採集された火山灰を含む氷層の自然残留磁気"},{"subitem_title":"Note on the natural remanent magnetizations of dirt-ice layers collected from the bare ice field in East Antarctica","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["1096"],"pubdate":{"attribute_name":"公開日","attribute_value":"1990-07-01"},"publish_date":"1990-07-01","publish_status":"0","recid":"8672","relation_version_is_last":true,"title":["東南極大陸の裸氷域から採集された火山灰を含む氷層の自然残留磁気"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:06:15.946499+00:00"}
