[meteorite-list] Ibitira--Not An HED Achrondrite

[Michael Fowler]

In doing research prior to purchasing an 18.5 gram slice of Ibitira, I 
came across the following:

Ibitira: A basaltic achondrite  from a distinct parent asteroid   by

Planetary Science

Apparently Ibitira is a unique representative of a fifth parent body 
with a basaltic (crust?).  The others are represented by NWA 011, the 
Angrites, Mesosiderites, and the HED's from Vesta.

Any comments, especially David Weir??

My goal, as a collector is to obtain a type specimen from as many 
different parent bodies as possible.  Since there are more than 135 
such bodies, and I have representatives of 25, I have a ways to go!
