66

EA shortened 67% at 900°C, 10-5/sec, and 1200 MPa with no melt; quartz regime 2 dislocation creep, feldspars semi-brittle (compare with 67).

EA shortened 67% at 900°C, 10-5/sec, and 1200 MPa, with little or no melt present. Quartz deformed by regime 2 dislocation creep, feldspars deformed by semi-brittle flow (transitional between cataclastic flow and regime 1 dislocation creep). Compare with photo 67 to see the effect of melt. (PMA8)
