[meteorite-list] How to tell IMB Gaos from normal

[MeteorHntr at aol.com]

Michael,

Actually, yes I have seen impact  melts before.  But to be honest, I am not 
sure I have seen the outside of a  Gao IMB.  It might be that I don't have any 
in the batches I have had  currently or before. 

I will assume if none of the ones I have now look  like a typical IMB, then 
that is probably the case.

How rare are the IMB  stones from Gao anyway?  1 out of a hundred?  More?   
Less?

Come on Steve, have you never seen the outside  of a
Gao impact-melt piece, or any impact melt for that
matter? It is  extremely easy to tell, it wont have
fusion crust on the melt parts, they are  glassy and
much harder.
