Hi to all, I know some of you enjoy thin section images, here is a series from what is likely to be an LL5-LL6 genomict breccia.
This is the neat 165g stone with multiple inclusions that I am getting classified.

What is the preliminary results?

LL5-LL6 genomict breccia containing clasts of:
-type 4 or type 5 LL chondrite
-type 6 LL chondrite
-fine-grained microbreccia clasts
-shock darkened clasts
-and impact melt litholies ranging from partially melted to totally melted equigranular and vitrophyiric objects (some of which show evidence of multiple heating events)
set w/in a fine grained accretionary matrix containing sparse, but well-defined chondrules.

And here are the tin section images - they are very nice, enjoy!
