Аннотация: The in-situ method of Raman spectroscopy was used to study the layered mineral phengite, K(Al,Mg)2(Si,Al)4O10(OH)2, compressed in water under simultaneously high temperatures and pressures (respectively, up to 373 °S and 12.5 GPa). The implemented conditions were typical of modeling the 'cold' subduction zones in lithospheric slabs. The high pressures and temperatures were produced in an electrically heated diamond-anvil cell. Measured Raman spectra have demonstrated a high R-T stability of the mineral. No non-quenchable phengite states (no reversible or irreversible polymorphic transitions, overhydration or notable amorphization) were observed in the investigated samples.
