The oldest Eocene arc has middle and lower crust with high velocities of 6.4-6.6 and 6.8-7.4 km/s, respectively, suggesting denser crustal materials. The current volcanic arc has middle and lower crust with lower velocities of 5.7-6.5 and 6.7-7.1 km/s, suggesting advanced crustal differentiation. The crust-mantle transition layer, with a velocity of 7.5-8.0 km/s, is distributed beneath the current volcanic arc and the rear arc, suggesting a pool of dense materials emanating from the crust through the crustal growth. These structural differences between the Eocene arc and current arc indicate a difference of crustal growth based on basaltic and andesitic magmas according to known petrologic studies. Commonly, rifted crusts have lower crusts with high velocities of over 7.0 km/s, and the arc-back arc transition zone also has a thinner more reflective crust that may have been affected by postrifting magmatism.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "AMER GEOPHYSICAL UNION", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1029/2008GC002146"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1525-2027", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Narumi Takahashi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Shuichi Kodaira", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Yoshiyuki Tatsumi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Mikiya Yamashita", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Takeshi Sato", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Yuka Kaiho", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Seiichi Miura", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Tetsuo No", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Kaoru Takizawa", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Yoshiyuki Kaneda", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "Structural variations of arc crusts and rifted margins in the southern Izu-Ogasawara arc-back arc system", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Structural variations of arc crusts and rifted margins in the southern Izu-Ogasawara arc-back arc system", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/4511", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "4511", "relation": {}, "relation_version_is_last": true, "title": ["Structural variations of arc crusts and rifted margins in the southern Izu-Ogasawara arc-back arc system"], "weko_shared_id": -1}
