Partial textures of regime 1, 2 and 3 of dynamic recrystallization

Higher magnification of experimentally deformed Black Hills quartzite (compare 4.5) and selective texture analysis of old grains and recrystallized grains (Tullis & Heilbronner, 1999).
Experimental conditions:
regime 1 (W871):

pc = 1.5 GPa

T = 850°C

strain rate = 10-5 s-1

as-is

regime 2 (W872):

pc = 1.5 GPa

T = 900°C

strain rate = 10-5 s-1

0.17 wt% water added

regime 3 (W858):

pc = 1.5 GPa

T = 900°C

strain rate = 10-6 s-1

0.17 wt% water added
