We performed high‐pressure, high‐temperature (400 MPa, 950°C–1200°C) torsion experiments on fine‐grained (size ≈4 <jats:italic>μ</jats:italic>m, aspect ratio ≈2.5) synthetic feldspar aggregates containing <3 vol% residual glass. Samples deformed at constant strain rates (≈2 × 10<jats:sup>−5</jats:sup> – 2 × 10<jats:sup>−4</jats:sup> s<jats:sup>−1</jats:sup>) to high strain (≈2.8–5.6) reveal strain hardening at the lower strain rates. Microstructures show pronounced cavitation and formation of porosity bands containing redistributed glass, presumably associated with grain boundary sliding and shape‐preferred orientation of high‐aspect ratio feldspar grains. Sudden failure by strain‐induced nucleation, growth and coalescence of the cavities occurred in one‐third of the samples before deformation was terminated. In natural mylonites cavitation damage may produce increased porosity enhancing fluid flow in high‐temperature shear zones.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670318860906497","@type":"Researcher","foaf:name":[{"@value":"Erik Rybacki"}],"jpcoar:affiliationName":[{"@value":"GeoForschungsZentrum Potsdam  Potsdam Germany"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670318860906496","@type":"Researcher","foaf:name":[{"@value":"Richard Wirth"}],"jpcoar:affiliationName":[{"@value":"GeoForschungsZentrum Potsdam  Potsdam Germany"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670318860906498","@type":"Researcher","foaf:name":[{"@value":"Georg Dresen"}],"jpcoar:affiliationName":[{"@value":"GeoForschungsZentrum Potsdam  Potsdam Germany"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00948276"},{"@type":"EISSN","@value":"19448007"}],"prism:publicationName":[{"@value":"Geophysical Research Letters"}],"dc:publisher":[{"@value":"American Geophysical Union (AGU)"}],"prism:publicationDate":"2008-02","prism:volume":"35","prism:number":"4","prism:startingPage":"L04304"},"reviewed":"false","dc:rights":["http://onlinelibrary.wiley.com/termsAndConditions#vor"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1029%2F2007GL032478"},{"@id":"https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/2007GL032478"}],"createdAt":"2008-02-22","modifiedAt":"2023-10-31","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360565166128846080","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"S-wave velocities and anisotropy of typical rocks from Yunkai metamorphic complex and constraints on the composition of the crust beneath Southern China"}]},{"@id":"https://cir.nii.ac.jp/crid/1360576118713913600","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Enhancement of ductile deformation in polycrystalline anorthite due to the addition of water"}]},{"@id":"https://cir.nii.ac.jp/crid/1390564238052793472","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Architecture of onshore fault zones"},{"@language":"ja","@value":"陸域断層の内部構造"},{"@language":"ja-Kana","@value":"リクイキ ダンソウ ノ ナイブ コウゾウ"}]},{"@id":"https://cir.nii.ac.jp/crid/2050588892078328960","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Strain localization and fabric development in polycrystalline anorthite + melt by water diffusion in an axial deformation experiment"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1029/2007gl032478"},{"@type":"CROSSREF","@value":"10.1186/s40623-017-0776-2_references_DOI_MO1OcxHEBMuApShOAKzm0VIlQsj"},{"@type":"CROSSREF","@value":"10.1016/j.jsg.2022.104547_references_DOI_MO1OcxHEBMuApShOAKzm0VIlQsj"},{"@type":"CROSSREF","@value":"10.5575/geosoc.2018.0004_references_DOI_MO1OcxHEBMuApShOAKzm0VIlQsj"},{"@type":"CROSSREF","@value":"10.1016/j.tecto.2016.07.017_references_DOI_MO1OcxHEBMuApShOAKzm0VIlQsj"}]}
