Northwest Africa 8781 C-ungr weighs 380 grams between several stones found together near Foum Zguid, Morocco, in July 2014. I find the reasoning for its classification informative. This is by the classifying scientist, Tony Irving.
This specimen is not a CV3 chondrite (chondrule size much too small, no CAI), not a CK chondrite (no magnetite), not a CO3 chondrite (oxygen isotopes are different, no CAI), and not a CM chondrite (matrix apparently anhydrous, oxygen isotopes displaced to more 16O-rich compositions). Therefore it seems to be an ungrouped carbonaceous chondrite.
