List of microstructures

 

 

 

 

99

 

Anorthosite deformed at granulite grade; plagioclase deformed by regime 2 dislocation creep, and recrystallized grains have same composition as host.

100

 

Anorthosite deformed at granulite grade (same as 99), plane polarized light; heterogeneous nucleation of hornblende between plagioclase grains.
