D'Orbigny Angrite
I got this thin section in the mail yesterday and was quite pleased. I never expected to find an Angrite thin section.
Angrites are a very rare type of meteorite, basically a type of basalt. They are the oldest igneous rocks ever found and are about 4.55 billion years old. Some theorize they are the result of melting of a carbonaceous chondrites parent body. The major minerals are augite and olivine.
The meteorite itself was plowed up in 1979 and kept for many years until in 2000 it was identified as an Angrite. There are currently 24 meteorites classified as Angrites.
Cheers.
