As a result, trench-slope cover sediments (Kinone and Amatsu Formations) are clearly distinguishable from the Early Miocene Hota accretionary complex (Hota Group). The Hota accretionary complex was deposited below the carbonate compensation depth (CCD) and was affected by intense shearing, forming an east–west trending and south-verging fold and thrust belt. In contrast, the trench-slope cover sediments basically have a homoclinal dip, except at the northern rim where they are bounded by fault contact. They contain many species of calcareous nannofossils and foraminifers, which are indicative of their depositional environment above the CCD, and they show shallowing-upward sedimentary structures. Biostratigraphy revealed that the depositional age of the trench-slope sediments is ca. 15–5.5 Ma, suggesting that there is an approximately 2 myr hiatus beween the Miura Group and the underlying accretionary prism. Based on these results, the age of accretion of the Hota Group is inferred to be between ca. 17–15 Ma, and the group is covered by trench-slope sediments overlain on it after ca. 15 Ma. The timing of accretion and the age of the trench-slope basin tend to be younger southward of the Boso Peninsula. The accretionary system of the Boso Peninsula apparently developed in two stages, in the Middle Miocene and in the Late Miocene to Pliocene."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1382262946316460928","@type":"Researcher","foaf:name":[{"@value":"Shun Chiyonobu"}]},{"@id":"https://cir.nii.ac.jp/crid/1382262946316460930","@type":"Researcher","foaf:name":[{"@value":"Yuzuru Yamamoto"}]},{"@id":"https://cir.nii.ac.jp/crid/1382262946316460929","@type":"Researcher","foaf:name":[{"@value":"Saneatsu Saito"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00401951"}],"prism:publicationName":[{"@value":"Tectonophysics"}],"dc:publisher":[{"@value":"Elsevier BV"}],"prism:publicationDate":"2017-07","prism:volume":"710-711","prism:startingPage":"56","prism:endingPage":"68"},"reviewed":"false","dc:rights":["https://www.elsevier.com/tdm/userlicense/1.0/"],"url":[{"@id":"https://api.elsevier.com/content/article/PII:S0040195116305546?httpAccept=text/xml"},{"@id":"https://api.elsevier.com/content/article/PII:S0040195116305546?httpAccept=text/plain"}],"createdAt":"2016-11-21","modifiedAt":"2018-09-06","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360004232523518848","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Tectono-seismic characteristics of faults in the shallow portion of an accretionary prism"}]},{"@id":"https://cir.nii.ac.jp/crid/1361412895411129472","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Vitrinite reflectance and consolidation characteristics of the post‐middle Miocene Forearc Basin in central and eastern Boso Peninsula, central Japan: Implications for basin subsidence"}]},{"@id":"https://cir.nii.ac.jp/crid/1390282681216262016","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Structural characteristics of shallow portion of plate subduction zone: A forearc system in the southern Boso Peninsula, central Japan"},{"@language":"ja","@value":"付加型沈み込み帯浅部の地質構造：房総半島南部付加体-被覆層システム"},{"@value":"巡検案内書 付加型沈み込み帯浅部の地質構造 : 房総半島南部付加体-被覆層システム"},{"@language":"ja-Kana","@value":"ジュンケン アンナイショ フカガタ シズミ コミ タイセンブ ノ チシツ コウゾウ : ボウソウ ハントウ ナンブ フカタイ-ヒフクソウ システム"}]},{"@id":"https://cir.nii.ac.jp/crid/2050588892078334976","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Slip parameters on major thrusts at a convergent plate boundary : regional heterogeneity of potential slip distance at the shallow portion of the subducting plate"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1016/j.tecto.2016.11.030"},{"@type":"OPENAIRE","@value":"doi_dedup___::86e8f33a7d6181b13ee3c5d9a86f79ed"},{"@type":"CROSSREF","@value":"10.1186/s40623-018-0810-z_references_DOI_iUI2qHsDjxinTWFRfokcj0s7RU"},{"@type":"CROSSREF","@value":"10.1016/j.tecto.2018.01.014_references_DOI_iUI2qHsDjxinTWFRfokcj0s7RU"},{"@type":"CROSSREF","@value":"10.5575/geosoc.2016.0057_references_DOI_iUI2qHsDjxinTWFRfokcj0s7RU"},{"@type":"CROSSREF","@value":"10.1111/iar.12344_references_DOI_iUI2qHsDjxinTWFRfokcj0s7RU"}]}
