Journal ArticleDOI
A new approach to develop the Raman carbonaceous material geothermometer for low-grade metamorphism using peak width
Yui Kouketsu,Tomoyuki Mizukami,Hiroshi Mori,Shunsuke Endo,Mutsuki Aoya,Hidetoshi Hara,Daisuke Nakamura,Simon Wallis +7 more
TL;DR: The Raman spectra of carbonaceous material (CM) from 19 metasediment samples collected from six widely separated areas of Southwest Japan and metamorphosed at temperatures from 165 to 655°C show systematic changes with metamorphic temperature that can be classified into four types: low-grade CM (c. 150-280°C), medium-grade graphite, high grade graphite and well-crystallized graphite (> c. 650°C) as discussed by the authors.
Journal ArticleDOI
Extending the applicability of the Raman carbonaceous-material geothermometer using data from contact metamorphic rocks
Mutsuki Aoya,Yui Kouketsu,Shunsuke Endo,H. Shimizu,H. Shimizu,Tomoyuki Mizukami,Daisuke Nakamura,Simon Wallis +7 more
TL;DR: In this paper, the area ratio (R2) of peaks recognized in Raman spectra of carbonaceous carbonaceous material (CM) was used as an indicator of metamorphic grade.
Journal ArticleDOI
Evaluation of residual pressure in an inclusion–host system using negative frequency shift of quartz Raman spectra
TL;DR: In this article, a new scheme of elastic modeling with equation of state (EOS) of quartz and garnet was proposed, which takes into account the pressure-and temperature-dependency of compressibility and expansivity.
Journal ArticleDOI
Omphacite-bearing metapelite from the Besshi region, Sambagawa metamorphic belt, Japan: Prograde eclogite facies metamorphism recorded in metasediment
TL;DR: Omphacite-bearing metapelite was found from the Seba area of the Besshi region, Sambagawa metamorphic belt, central Shikoku, Japan as discussed by the authors.
Journal ArticleDOI
Composite metamorphic history recorded in garnet porphyroblasts of Sambagawa metasediments in the Besshi region, central Shikoku, Southwest Japan
TL;DR: In this article, the authors investigated the composite metamorphic history recorded in garnet porphyroblasts of Sambagawa metasediments, and discussed the possible distribution of eclogite facies lithologies in the Besshi region, central Shikoku, southwest Japan.
