Comparison between Raman spectra of carbonaceous material and carbon isotope thermometries in low-medium grade meta-carbonates: Implications for estimation of metamorphic temperature condition

Genesis of the Graphite from the Tugeman Graphite Deposit, Xinjiang, China: Evidence for Carbon Isotope Refining by Fluids Associated with the Ductile Shear Zone

“…Previous research has demonstrated the efficacy of Raman spectroscopy in determining the peak temperature of carbonaceous materials [101]. In this study, alongside qualitative observations of the Raman spectrum of graphite, the peak temperature was quantitatively determined using the calculation formula proposed by Beyssac et al [101], as it is best suited for regional metamorphic terrain [105]. The formula is as follows:…”

Carbon isotopic composition of graphite in metamorphic rocks from Lützow-Holm Complex, East Antarctica: Implications for carbon geodynamic cycle in continental crust

“…Several previous studies have considered the graphitization process from a graphite crystallinity perspective. Only few studies have addressed isotopic evolution during prograde metamorphism, (e.g., Wada et al, 1995;Ueno et al, 1992Nakamura et al, 2015Kiran et al, 2021), where they found that graphitization is associated with a concomitant isotopic enrichment in graphite. This is consistent with our observations in high-grade metamorphosed silicate rocks in LHC in this study.…”
