According to the Perceived Service Quality model (Figure 1), the quality of a service, as perceived by the customer, is the result of a comparison between the expectations of the customer and his or her real-life experiences.
Resorption of garnet I may have occurred either as a result of the prograde univariant reaction Grt + Chl + Ms = St + Bt + Qtz + H2O, or during decompression, by the net transfer reaction Grt + Ms + H2O = St + Bt + Qtz, before staurolite had become unstable.
11. A regional metamorphic rock with coarse inter-locking grains generally formed under conditions of relatively high pressures and temperatures. 12. A metamorphic rock formed under conditions of high pressure and relatively low temperatures, often contains the minerals glaucophane and kyanite. metamorphic schist containing chlorite and epidote and are formed by low-temperature, low-pressure metamorphism. 14. metamorphism occurs at high-temperatures and pressures, by the crushing and shearing of rock during tectonic movements and resulting in the formation of powdered rock.
