Its been a while but I do remember reading in the Mineralogical Society of
America's book "Planetary Minerals" that the angrite parent body was some
sort of carbonaceous chondrite though I don't remember which subgroup.

On thing really makes me wonder. All those strange meteorites, angrites in
particular, one recently found in Argtentina with really large bubbles.
These are highly differentiated meteorites. Could they be fragments of
Murcury?

Any thoughts on this?

Certainly magmatic processes on the planet Murcury would have ended at about
the same time as they did on the moon-- about 3.9 billion years ago. What
is the age date angrites?
