Samples used are quartz aggregates deformed under high temperature (800 °C, 900 °C and 1000 °C) and high confining pressure (400 MPa). The fractal dimension is useful to quantify the shapes of the recrystallized quartz grain boundaries. At each set of conditions, the fractal dimension is determined as the slope of a log—log plot of the length of the grain boundaries (perimeters) against the grain size, calculated as diameters of circles having the same areas as the actual grains. The results show that the shapes of grains are self-similar, and the fractal dimensions,  D , change systematically, being dependent on both temperature and strain rate. The skew of the grain boundary, defined as  D  − 1, and showing the degree of the serration, may be proportional to the logarithm of the Zener-Hollomon parameter that includes a component of the Arrhenius term. This relation indicates that strain rate can be calculated from the fractal dimension and the temperature. It may therefore provide a new paleo-strain rate meter for plastically deformed natural rocks."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383951795698608387","@type":"Researcher","foaf:name":[{"@value":"Miki Takahashi"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951795698608385","@type":"Researcher","foaf:name":[{"@value":"Hiroyuki Nagahama"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951795698608386","@type":"Researcher","foaf:name":[{"@value":"Toshiaki Masuda"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951795698608384","@type":"Researcher","foaf:name":[{"@value":"Akio Fujimura"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"01918141"}],"prism:publicationName":[{"@value":"Journal of Structural Geology"}],"dc:publisher":[{"@value":"Elsevier BV"}],"prism:publicationDate":"1998-02","prism:volume":"20","prism:number":"2-3","prism:startingPage":"269","prism:endingPage":"275"},"reviewed":"false","dc:rights":["https://www.elsevier.com/tdm/userlicense/1.0/","https://www.elsevier.com/legal/tdmrep-license"],"url":[{"@id":"https://api.elsevier.com/content/article/PII:S0191814197000722?httpAccept=text/xml"},{"@id":"https://api.elsevier.com/content/article/PII:S0191814197000722?httpAccept=text/plain"}],"createdAt":"2002-07-25","modifiedAt":"2025-10-01","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050012570392438528","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Water distribution in quartz schists of the Sanbagawa Metamorphic Belt, Japan: infrared spectroscopic mapping and comparison of the calibrations proposed for determining water contents"}]},{"@id":"https://cir.nii.ac.jp/crid/1360016864725504128","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Steady-State Microstructures of Quartz Revisited: Evaluation of Stress States in Deformation Experiments Using a Solid-Medium Apparatus"}]},{"@id":"https://cir.nii.ac.jp/crid/1360568470480986496","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Distribution of ductile deformation around the Main Central Thrust zone at the frontal part of nappe in southeastern Nepal Himalaya"}]},{"@id":"https://cir.nii.ac.jp/crid/1390001204598536064","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Skin Depth of Electromagnetic Wave through Fractal Crustal Rocks"},{"@language":"ja","@value":"地殻岩石の電磁波スキンデプスとフラクタル特性"}]},{"@id":"https://cir.nii.ac.jp/crid/1390282679588385792","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"The Correlation between the Fractal Dimension and Internal Friction Angle of Different Granuiar Materials."},{"@value":"The Correlation Between the Fractal Dimension and Internal Friction Angle of Different Granular Materials"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1016/s0191-8141(97)00072-2"},{"@type":"OPENAIRE","@value":"doi_dedup___::2c83cbd024d51894aad8f80bcada33d3"},{"@type":"CROSSREF","@value":"10.3390/min12030329_references_DOI_OBIPcwuWlcWjiK8XAKz5JO6DxNo"},{"@type":"CROSSREF","@value":"10.1111/iar.12333_references_DOI_OBIPcwuWlcWjiK8XAKz5JO6DxNo"},{"@type":"CROSSREF","@value":"10.1541/ieejfms.130.258_references_DOI_OBIPcwuWlcWjiK8XAKz5JO6DxNo"},{"@type":"CROSSREF","@value":"10.1186/s40623-019-1117-4_references_DOI_OBIPcwuWlcWjiK8XAKz5JO6DxNo"},{"@type":"CROSSREF","@value":"10.3208/sandf.41.6_17_references_DOI_OBIPcwuWlcWjiK8XAKz5JO6DxNo"}]}
