Big thin section of Rumurutite R3 NWA 13758.
Chondrite with mean apparent chondrule size 350±240 μm (n=21) set in abundant matrix (~35 vol%).
Electron microprobe analyses were performed separately on the two main lithologic domains.
Domain "A" has compositionally unequilibrated olivine and pyroxene both in chondrules as well as single mineral fragments in the matrix. Very small grains of albitic plagioclase are present. Chromite, pentlandite, and troilite are ubiquitous. No metal or oxidized iron was detected.
Domain "B" has compositionally unequilibrated olivine and pyroxene both in chondrules as well as single mineral fragments in the matrix.
Domain "B" appears to have slightly more chondrules than domain "A". Very small grains of albitic plagioclase were present. Ti-rich chromite, pentlandite, and Ni-bearing troilite are ubiquitous. No metal or oxidized iron was detected.

Quick shipping with FedEx to the US. The stone has the polarization expected with real Iceland spar. I'm very happy with this purchase!

Quick shipping with FedEx to the US. It was well packaged. The one I received did have a small crack and chip in the lip, but stuff like that is expected with a natural material like this. I'm happy with my purchase.
