Hello list,

I have been having fun with my BL meteorites and just aquired a nice ~100 
gram slice.

There was much discussion about this LL5 meteorite a while ago because of 
its gorgeous crust.  Not so much discussion on its interior.  My new slice 
is incredible!  It has large homogeneous grey clasts which do not attract 
magnets.  I was wondering if these clasts are achondritic?  Can an LL5 
brecciated meteorite include abundant achondritic clast or would this alter 
its classification

Does anyone have more info on its classification?  The Met Bull. still lists 
this as provisional.

The first pic is of my new slice.  Notice the large central inclusion.
The second pic is a smaller 6 gram end slice and the third pic is my 66 gram 
beautiful individual.

Jeff Kuyken also has some nice pics and info on this stuff.
