This 1.86g fusion crusted full slice of NWA 7309 CM2 (S2,W1) features an interesting CAI that looks like Pac-Man about to eat a power pellet (chondrule) in the 80s arcade game. I purchased a lot of 2 freshly fusion crusted stones from a dealer in Agadir, Morocco in March 2012. The stone was incredibly fresh, with flowlined and frothy fusion crust covering about 60% of the stone. It was a sight through the other 40% of the stone that made me excited: a dark, fine grained matrix with small light chondrules, not unlike a Murchison, Mighei or Murray.
The meteorite was cut by Montana Meteorite Laboratory and a sample submitted to Dr Tony Irving for analysis toward classification. He reports the meteorite consists of small chondrules, some mineral fragments and sparse, fine grained CAI in a very dark, slightly stained matrix containing cronstedtite-tochilinite and minor pentlandite. Olivine (Fa0.5-43.9), orthopyroxene (Fs1.2-1.3Wo2.6-0.9), clinopyroxene (Fs4.1Wo39.6). This is my third CM, the freshest yet, and a beautiful representation of a CM2 carbonaceous chondrite, featuring stunning chondrules and Calcium Aluminum Inclusions (CAI) throughout the matrix.
