List/Darren you had asked once about granite. I don't remember if was a
compositional or an origin issue.
I do know that granite's crystaline structure results from slow cooling
under monumental pressures [substantially 5 miles of overburden is a
commonly mentioned denominator-often referred to as "the roots of
mountains".
So what if anything does this tell us about Vesta's possible history?
