In recent years, various methods have been proposed for Raman geobarometry, such as a method for correcting the peak position and for constraining the metamorphic pressure, and problems have been raised with the methods proposed by Enami et al. (2007) and Kouketsu et al. (2014). In this study, we examined the following two points in light of this situation. (1) Evaluation of the error of the residual pressure value using peak width, and (2) Verification of the anisotropy of residual pressure and strain values of quartz inclusions in natural samples.
