Northwest Africa 7411 (NWA 7411)

(Northwest Africa)

Purchased: Nov 2010

Classification: Carbonaceous chondrite (CV3)

Petrography: (A.E. Rubin, UCLA) There are large (2-3 cm) type A fluffy CAIs and 1-2 cm type B CAIs visible in hand sample. Chondrules average about 900 μm in apparent diameter, characteristic of CV chondrites.  Many chondrules have thick igneous rims.  There are a few percent AOIs, which have a mean size of ~700 μm.  The rock has moderately abundant magnetite and little metallic Fe-Ni.  Some of the low-Ca pyroxene grains exhibit polysynthetic twins.
