Experimentally deformed feldspar aggregates

Starting material / cataclastic flow / regime 1

TA shortened 50% at 800°C, 10-5/sec, and 1200 MPa; semi-brittle flow.

TA shortened 50% at 800°C, 10-5/sec, 1200 MPa. This sample deformed by semi-brittle flow; TEM shows that there was limited dislocation glide, but no recovery or recrystallization, and thus extreme work hardening resulted in distributed microcracking. This sample demonstrates that multiple grain-scale faulting can produce a grain shape foliation. (W447)
