In this study, we propose a realistic 3-D resistivity model to explain anomalous phase data through the use of an L-shaped conductor model. The model presented here consists of a large, elongated conductor (a regional conductor) and a small, square conductor attached to a longer side of the regional conductor. In this model, telluric current is locally reversed and hence out of the ordinal quadrant phase is derived at the edge of the local conductor. Although conventional distortion analyses for galvanic distortion cannot remove anomalous phase problem, we showed that some impedance parameters are not distorted by the anomalous telluric current. Because the ‘L’ shaped conductor model is simple and broadly applicable to realistic resistivity distributions, it represents an important contribution to the construction of an appropriate model to explain various magnetotelluric data, including anomalous phase data."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1382825895326961409","@type":"Researcher","foaf:name":[{"@value":"Hiroshi Ichihara"}]},{"@id":"https://cir.nii.ac.jp/crid/1382825895326961408","@type":"Researcher","foaf:name":[{"@value":"Toru Mogi"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"0956540X"},{"@type":"EISSN","@value":"1365246X"}],"prism:publicationName":[{"@value":"Geophysical Journal International"}],"dc:publisher":[{"@value":"Oxford University Press (OUP)"}],"prism:publicationDate":"2009-10","prism:volume":"179","prism:number":"1","prism:startingPage":"14","prism:endingPage":"17"},"reviewed":"false","dcterms:accessRights":"http://purl.org/coar/access_right/c_abf2","url":[{"@id":"http://academic.oup.com/gji/article-pdf/179/1/14/17360260/179-1-14.pdf"}],"createdAt":"2009-08-11","modifiedAt":"2019-02-22","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050025031477811328","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Crustal structure and fluid distribution beneath the southern part of the Hidaka collision zone revealed by 3-D electrical resistivity modeling"},{"@value":"Crustal structure and fluid distribution beneath the southern part of the <scp>H</scp>idaka collision zone revealed by 3‐<scp>D</scp> electrical resistivity modeling"}]},{"@id":"https://cir.nii.ac.jp/crid/1360285707500072704","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Three-dimensional resistivity modelling of a seismogenic area in an oblique subduction zone in the western Kurile arc: Constraints from anomalous magnetotelluric phases"}]},{"@id":"https://cir.nii.ac.jp/crid/1360298345525014656","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Magmatic fluid pathways in the upper crust: insights from dense magnetotelluric observations around the Kuju Volcanoes, Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1390001206525416448","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"ja","@value":"地殻・上部マントルの電気比抵抗構造：観測の原理・精度と物性データの現状"},{"@language":"en","@value":"An overview of electrical resistivity in the crust and upper mantle: principle of magnetotelluric method, accuracy and resolution of resistivity modeling, and electrical resistivity feature of crustal and mantle rocks and minerals"},{"@language":"ja-Kana","@value":"チカク ジョウブ マントル ノ デンキヒ テイコウ コウゾウ カンソク ノ ゲンリ セイド ト ブッセイ データ ノ ゲンジョウ"}]},{"@id":"https://cir.nii.ac.jp/crid/2050025942186660864","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"A 3-D electrical resistivity model beneath the focal zone of the 2008 Iwate-Miyagi Nairiku earthquake (M 7.2)"}]},{"@id":"https://cir.nii.ac.jp/crid/2050307417117558784","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Validity of the dispersion relations in magnetotellurics : Part I—theory"}]},{"@id":"https://cir.nii.ac.jp/crid/2051151842051751936","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Validity of the dispersion relations in magnetotellurics.
