Use of the satellite derived gravity map to approximate the ocean-continent boundary allows us to generate a much tighter fit for the reconstructed supercontinent then previously attempted. Major mantle plumes such as the Karoo-Ferrar Plume that first split Gondwana at about 182Ma, the Parana-Etendeka plume at 132Ma that split South America and Africa, the Marion plume at 88Ma that split Madagascar and India and finally the Reunion hotspot that split the Mascarene Plateau from India at 64Ma, were all critical events in the break-up of Gondwana. Our tight-fit produces overlap between cratonic East Antarctica and the Limpopo Plain of Mozambique but there is no evidence that the crustal material underlying the Limpopo Plain pre-dates the break-up of Gondwana. Likewise Madagascar has been reconstructed so that it substantially overlies coastal East Africa in the vicinity of the Anza Trough, an early Jurassic rift in Kenya. The western margin of the island of Madagascar may in fact be crustal material that is younger than the break-up. It may have been produced as a result of the Karoo mantle plume or some may have been the result of the Marion hotspot. Between South America and Africa there are three significant overlaps. Two of them are deltaic, and the third is the Abrolhos and Royal Charlotte banks which post-date Gondwanide breakup by 80 to 100 million years.","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":"Institute for Geophysics, University of Texas/Institute for Geophysics, University of Texas/Institute for Geophysics, University of Texas"}]},"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":"KJ00000012899.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000012899","url":"https://nipr.repo.nii.ac.jp/record/2347/files/KJ00000012899.pdf"},"version_id":"03911d6c-3598-4ea7-82b4-47f03c805bf7"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Gondwana break-up","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Mesozoic Paleoreconstructions","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ocean-continent boundaries","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Karoo-Ferrar Mantle Plume","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"overlap","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":"A Tight fit-Early Mesozoic Gondwana, a Plate Reconstruction Perspective","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A Tight fit-Early Mesozoic Gondwana, a Plate Reconstruction Perspective","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":"2347","relation_version_is_last":true,"title":["A Tight fit-Early Mesozoic Gondwana, a Plate Reconstruction Perspective"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:56:37.487602+00:00"}
