A superevent cycle involves supercontinent breakup that initiates both slab avalanches and the onset of formation of a new supercontinent; arrival of slabs at the D\" layer triggers mantle plumes that rise and bombard the base of lithosphere producing juvenile crust trapped in the growing supercontinent; and shielding of the mantle beneath the new supercontinent results in a mantle upwelling that eventually breaks the supercontinent as the cycle starts over. Superevents comprise three or four events each of 50-80 My duration, each of which may reflect slab avalanches at different locations and times at the 660-km discontinuity. Superplume events in the late Paleozoic and Mid-Cretaceous may have been caused by minor slab avalanches as the 660-km discontinuity became more permeable to the passage of slabs. The total duration of a superevent cycle decreases with time probably reflecting the cooling of the mantle.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733561","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Earth & Environmental Science, New Mexico Institute of Mining and Technology"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1998-12-01"}],"displaytype":"detail","filename":"KJ00000012887.pdf","filesize":[{"value":"569.5 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000012887","url":"https://nipr.repo.nii.ac.jp/record/2335/files/KJ00000012887.pdf"},"version_id":"20002734-ff1f-46c6-a8c7-1221dbda7857"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"crustal growth","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"supercontinents","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"mantle plumes","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"episodic ages","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":"Episodic growth of juvenile crust and catastrophic events in the mantle","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Episodic growth of juvenile crust and catastrophic events in the mantle","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["407"],"pubdate":{"attribute_name":"公開日","attribute_value":"1998-12-01"},"publish_date":"1998-12-01","publish_status":"0","recid":"2335","relation_version_is_last":true,"title":["Episodic growth of juvenile crust and catastrophic events in the mantle"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:56:47.620904+00:00"}
