Thermomechanical models for channel flow link such extrusion to focused orographic precipitation at the surface. Isotopic constraints on the timing of fault movement, anatexis and thermobarometric evolution of the exhumed garnet- to sillimanite-grade metasedimentary rocks support mid-crustal channel flow during the Early to Mid-Miocene. Exhumed metamorphic assemblages suggest that the dominant mechanism of the viscosity reduction that is a requirement for channel flow was melt weakening along the upper surface, defined by the South Tibetan Detachment System, and strain softening along the base, bounded by the Main Central Thrust. Neotectonic extrusion, bounded by brittle Quaternary faults south of the Main Central Thrust, is positively correlated with the spatial distribution of precipitation across a north–south transect, suggesting climate–tectonic linkage over a million-year time scale. A proposed orogen-wide eastward increase in extrusion rate over 20 Ma reflects current precipitation patterns but climate–tectonic linkage over this time scale remains equivocal.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381418519733007488","@type":"Researcher","foaf:name":[{"@value":"Nigel Harris"}],"jpcoar:affiliationName":[{"@value":"Department of Earth Sciences, The Open University, Walton Hall, Milton Keynes MK7 6AA, UK (e-mail: n.b.w.harris@open.ac.uk)"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00167649"},{"@type":"EISSN","@value":"2041479X"}],"prism:publicationName":[{"@value":"Journal of the Geological Society"}],"dc:publisher":[{"@value":"Geological Society of London"}],"prism:publicationDate":"2007-05","prism:volume":"164","prism:number":"3","prism:startingPage":"511","prism:endingPage":"523"},"reviewed":"false","dc:rights":["https://doi.org/10.15223/policy-002"],"url":[{"@id":"https://www.lyellcollection.org/doi/pdf/10.1144/0016-76492006-133"}],"createdAt":"2007-05-04","modifiedAt":"2024-07-23","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360567182127259904","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Supercooled melt inclusions in lower-crustal granulites as a consequence of rapid exhumation by channel flow"}]},{"@id":"https://cir.nii.ac.jp/crid/1360848661184952704","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Early Oligocene partial melting via biotite dehydration melting and prolonged low-pressure–low-temperature metamorphism of the upper High Himalaya Crystalline Sequence in the far east of Nepal"}]},{"@id":"https://cir.nii.ac.jp/crid/1390566775132635392","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"The Indo–Eurasia convergent margin and earthquakes in and around Tibetan Plateau"}]},{"@id":"https://cir.nii.ac.jp/crid/2051151841908060032","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Evolution and variability of the Asian monsoon and its potential linkage with uplift of the Himalaya and Tibetan Plateau"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1144/0016-76492006-133"},{"@type":"CROSSREF","@value":"10.1186/s40645-016-0080-y_references_DOI_6yEM3hZYHRUBSFGvCCsoErwPZb9"},{"@type":"CROSSREF","@value":"10.1144/sp481.2_references_DOI_6yEM3hZYHRUBSFGvCCsoErwPZb9"},{"@type":"CROSSREF","@value":"10.1016/j.gr.2013.04.001_references_DOI_6yEM3hZYHRUBSFGvCCsoErwPZb9"},{"@type":"CROSSREF","@value":"10.2465/jmps.190927_references_DOI_6yEM3hZYHRUBSFGvCCsoErwPZb9"}]}
