Hi
First You can make few thin section for lab or choose most representative
1x1" slice for one thin section.

Second for example "NWA869 family" dont have soo many huge breccias for make
from them thin section. Ofcourse if You want cheated classifiction, You will
find clean L4 part and this one You can send to lab. For some reasons this
will be cheat, for others not, becouse THIS L4 fragment is part of whole
meteorite. But this will be not representative material.

I think that for brecciated meteorites must be submited more than 1 thin
section to minimize possibility of wrong classification.
