Experimentally deformed feldspar aggregates

Starting material / cataclastic flow / regime 1

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

TA shortened 35% at 900°C, 10-6/sec,1200 MPa. In this sample the starting material had well-aligned laths, which were oriented parallel to the sample core axis and thus parallel to compression. During the deformation the sample buckled; the original foliation is almost vertical in the lower left corner, curves around to the right, and then becomes vertical again in the upper right corner. Very thin dextral shear zones of (regime 1) dynamically recrystallized grains have developed (NW-SE) and are accommodating almost all of the further sample strain. (W694)
