6.4 grams. 43 x 37 x 2 mm.   CR2

TKW 707 grams. Fall not observed. Purchased February 2015.

Geoff writes:
With a small total known weight of 707.3 grams, Aerolite acquired six identical appearing full stones with smooth abraded fusion crust. A saw cut reveals many distinct chondrules of variable size set in a dark-gray groundmass.

This rare, newly classified CR2 is thought to have been heated at higher temperatures as compared to other carbonaceous chondrites (CI/CM) and formed in an aqueous environment. NWA 10256 is an Aerolite exclusive!

Good question 'Z'. Do we not trust the MetBul?

I am curious about the comments here which state surprise that this is a CR2 rather than CV3. Why? Is it the lack of metal? Perhaps that is just the angle of the photo... are there other reasons? Also... is the met bull list not conclusive? In other words, if it's classified as a CR2, then it's a CR2 pretty much without question... right?

That's a nice CV3.

Although in the first image it does have more chondrules similar to CR and CAIs are more unusual.

Me too Aziz...I would have been sure it was a CV3.
