In situ Raman spectroscopic study of interaction between phengite and water under P–T conditions typical of subduction zones

In situ Raman spectroscopy is used to study the layered mineral phengite K(Al, Mg) 2 (Si, Al) 4 O 10 (OH) 2 in water under the high temperature and pressure conditions typical of cold subduction zones ( T up to 373°C and P = 12.5 GPa). High pressure and temperature were created in a resistively heat...

Description
Summary:In situ Raman spectroscopy is used to study the layered mineral phengite K(Al, Mg) 2 (Si, Al) 4 O 10 (OH) 2 in water under the high temperature and pressure conditions typical of cold subduction zones ( T up to 373°C and P = 12.5 GPa). High pressure and temperature were created in a resistively heated diamond anvil cell. Raman spectra show the high P – T stability of phengite. No reversible polymorphic transitions (overhydration or notable amorphization) are observed.
