Grapevine Mesa CBa Meteorite
Grapevine Mesa stones have a rusty exterior with some remaining patches of fusion crust. Slices made from Grapevine Mesa show rounded to angular silicate inclusions accompanied by rounded to anhedral metal grains. The metal of Grapevine Mesa closely resembles the meteorite Bencubbin. Grapevine Mesa has been placed in the subgroup A (CBa) of the Bencubbin-like Carbonaceous Chondrites. Bencubbin-like Carbonaceous Chondrites are very expensive and these small fragments make this rare classification of meteorite much more affordable.
