It is a 1000-km-long ridge oriented northwest to southeast and is cut by north-south–trending fracture zones. Hypotheses about the origin and development of the Central Basin fault have remained unresolved until recently. Submersible observations and SeaBeam surveys show that the Central Basin fault is a segmented spreading ridge having a morphology similar to that of a slow spreading ridge, with a nontransform offset, a nodal deep, and an inside corner high. The distance from the ridge versus the depth of the sea floor, the obliqueness of sets of small trough and ridge structures, and heat-flow values both of the crestal and off-axis areas of the Central Basin fault suggest that the fault is not a simple spreading center, but rather underwent multiple spreading episodes. The texture and chemistry of basalts obtained from the ridge suggest that the lavas were formed in a backarc basin setting. These data confirm that the Central Basin fault is a slow backarc spreading center that has a more complicated evolutionary history than previously realized."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381137043642887297","@type":"Researcher","foaf:name":[{"@value":"Kantaro Fujioka"}]},{"@id":"https://cir.nii.ac.jp/crid/1381137043642887168","@type":"Researcher","foaf:name":[{"@value":"Kyoko Okino"}]},{"@id":"https://cir.nii.ac.jp/crid/1381137043642887300","@type":"Researcher","foaf:name":[{"@value":"Toshiya Kanamatsu"}]},{"@id":"https://cir.nii.ac.jp/crid/1381137043642887298","@type":"Researcher","foaf:name":[{"@value":"Yasuhiko Ohara"}]},{"@id":"https://cir.nii.ac.jp/crid/1381137043642887301","@type":"Researcher","foaf:name":[{"@value":"Osamu Ishizuka"}]},{"@id":"https://cir.nii.ac.jp/crid/1381137043642887296","@type":"Researcher","foaf:name":[{"@value":"Saturu Haraguchi"}]},{"@id":"https://cir.nii.ac.jp/crid/1381137043642887299","@type":"Researcher","foaf:name":[{"@value":"Teruaki Ishii"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00917613"},{"@type":"PISSN","@value":"https://id.crossref.org/issn/00917613"}],"prism:publicationName":[{"@value":"Geology"}],"dc:publisher":[{"@value":"Geological Society of America"}],"prism:publicationDate":"1999","prism:volume":"27","prism:number":"12","prism:startingPage":"1135"},"reviewed":"false","createdAt":"2002-07-27","modifiedAt":"2018-03-08","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360004235527894528","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Low‐ and high‐temperature alterations of volcanic rocks in the northwestern <scp>P</scp>hilippine <scp>S</scp>ea, and association with volcanic settings"}]},{"@id":"https://cir.nii.ac.jp/crid/1360583258211380992","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Geophysical investigation of the Mado Megamullion oceanic core complex: implications for the end of back-arc spreading"}]},{"@id":"https://cir.nii.ac.jp/crid/1360848660932554112","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Upwelling, rifting, and age-progressive magmatism from the Oki-Daito mantle plume"}]},{"@id":"https://cir.nii.ac.jp/crid/1390001204236634624","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"ja","@value":"フィリピン海の海盆形成とマグマティズム"},{"@language":"en","@value":"Basin Genesis and Magmatism in the Philippine Sea"},{"@language":"ja-Kana","@value":"フィリピンカイ ノ カイボン ケイセイ ト マグマティズム"}]},{"@id":"https://cir.nii.ac.jp/crid/1390001204236635776","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"ja","@value":"フィリピン海の磁気異常とテクトニクス"},{"@language":"en","@value":"Magnetic Anomalies in the Philippine Sea: Implications for Regional Tectonics"},{"@language":"ja-Kana","@value":"フィリピンカイ ノ ジキ イジョウ ト テクトニクス"},{"@value":"Magnetic anomalies in the Philippine Sea: implications for regional tectonics [in Japanese with English abstract]"}]},{"@id":"https://cir.nii.ac.jp/crid/2050307417163378944","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"A revised spreading model of the West Philippine Basin"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1130/0091-7613(1999)027<1135:eescit>2.3.co;2"},{"@type":"OPENAIRE","@value":"doi_dedup___::2f9a5433a412e37d4837ea9df700e594"},{"@type":"CROSSREF","@value":"10.1111/iar.12078_references_DOI_OFxAMnJ887JUR0J2fQsvVe8IDJO"},{"@type":"CROSSREF","@value":"10.1186/s40645-023-00570-2_references_DOI_OFxAMnJ887JUR0J2fQsvVe8IDJO"},{"@type":"CROSSREF","@value":"10.1130/g34525.1_references_DOI_OFxAMnJ887JUR0J2fQsvVe8IDJO"},{"@type":"CROSSREF","@value":"10.1186/1880-5981-66-83_references_DOI_OFxAMnJ887JUR0J2fQsvVe8IDJO"},{"@type":"CROSSREF","@value":"10.5026/jgeography.124.773_references_DOI_OFxAMnJ887JUR0J2fQsvVe8IDJO"},{"@type":"CROSSREF","@value":"10.5026/jgeography.124.729_references_DOI_OFxAMnJ887JUR0J2fQsvVe8IDJO"}]}
