50			Detail of anorthosite weakly deformed at ~700°C, 900 MPa; regime 2 dislocation creep. Incipient recystallization in a weakly deformed anorthosite. Core and mantle structures, resulting from subgrain rotation recrystallization, are common in many plagioclase grains. Crystal plastic deformation of plagioclase is evident from bent twin lamellae and undulose extinction. Other phases present include hornblende and garnet.
