Abstract

The behavior of CaBSiO4(OH) datolite compressed in a water medium at simultaneous high temperatures and pressures corresponding to the cold zones of tectonic plate subduction (up to P ~5.3 GPa and T ~250°C) is studied in situ via Raman spectroscopy. Two polymorphic transitions are found: (i) upon an increase of up to 2 GPa in pressure at a constant temperature of 22°C and (ii) upon heating to ~90°C at a constant pressure of ~5–5.3 GPa. Major trends of the variations in the Raman spectra are identified for all phases of the indicated P–T parameters. No overhydration and amorphization of datolite is observed.
