Good morning Steve, Greg and List,

metamorphism resulting in recrystalization. The composition is much the same as
in the original chondrite. There are different affinities, such as 'H' 'L' or 'LL'.
I think there are others including E's and 'C' chondrites."
That's right. One further, important aspect is that they are all virtually without
(relic) chondrules, devoid of chondrules with a few minor exceptions. See here:
