45

 

HA shortened 56% at 1000°C, 10-6/sec, and 1200 MPa; regime 1 dislocation creep.

46

 

HA shortened 70% at 1100°C, 10-6/sec, and 1200 MPa; regime 1 dislocation creep.

36

 

TA shortened 52% at 1100°C, 10-5/sec, and 1200 MPa; regime 1 dislocation creep.

37

 

TA shortened 35% at 900°C, 10-6/sec, and 1200 MPa; localized dextral shear zone has formed due to regime 1 dislocation creep.

38

 

TA shortened 35% at 900°C, 10-6/sec, and 1200 MPa; narrow zones of very fine recrystallized grains (regime 1 dislocation creep) allow localized dextral shear.

39

 

TA pre-faulted at low P and T, then shortened 30% at 900°C, 10-6/sec, and 1200 MPa; regime 1 dislocation creep localized along former fault.
