Hi Rob Nice piece, but I would like a bit of clarification. I believe there have been other chondrites like yours with a mix of different lithologies, but simply classified as L6 or LL6 polymict breccias. What sets yours apart? I am just trying to understand the differences here...

Hello Bernd and List, Thanks alot for all your congratulations! Actually (luckily) it was not that hard a decision to cut Mike. Originally it was fractured at that side :-). The stone consist of cm-sized dark L4 clasts (Fa 25.58+0.53, Fs 22.2+0.31) in LL6 (Fa 31.53±0.64, Fs 26.54+0.44) material.
