EA shortened 60% at 800°C, 10-6/sec, and 1200 MPa (same as 64); then annealed at
900°C for 120 hrs.

EA deformed at exactly the same conditions as the sample shown in photo #64 and then hydrostatically annealed at 900°C for 120 hours. Many quartz grains show a necklace of coarse 'square' recrystallized grains. One feldspar grain shows evidence of multiple grain-scale faults. The recrystallized feldspar grains resulting from the anneal are much finer than the recrystallized quartz grains; some patches of recrystallized feldspar can be seen in the top right and left center of the photo.
