Or maybe just high pressure - heat may not be necessary to make mineral grains align (or flatten?) perpendicular to the direction of greatest stress. I'm pretty fuzzy on this though... Is there a structural geologist in the house? Pretty interesting - does anybody know of good reading material that touches on extraterrestrial structural geology or if much of the same geology principals apply to low gravity environments?
