Fig. 7From: Mass transfer in the Earth’s interior: fluid-melt interaction in aluminosilicate–C–O–H–N systems at high pressure and temperature under oxidizing conditionsRaman spectra of COH fluids at 600°, 700°, and 800 °C and corresponding pressures (see Table 1). The peak near 1070 cm−1 is assigned to C–O stretch vibrations in CO3 groups (Frantz et al. 1993) and marked CO3Back to article page
