Shock Metamorphism - meteor impact generated metamorphism. Usually characterized by hi P, low T polymorphs. Fabric Fabric - arrangement and orientation of the mineral grains in space. A reflection of the nature of the stress applied. Definitely related to surface anistrophy, but why is uncertain.
Analogy is a bag of marbles.
Massive - lacking anisotropic fabric on outcrop scale. Granoblastic - lacking anisotropic fabric at the thin section level. Results in foliation. Examples are schistosity and slaty cleavage. Rather rare by itself.
