Writeup from MB 103:

Northwest Africa 8026 (NWA 8026)

(Northwest Africa)

Purchased: 2003

Classification: Carbonaceous chondrite (CV3)

Petrography: The sample consists of relatively large chondrules and CAIs set in a fine-grained matrix. Chondrules in the section studied are up to 3500 μm in diameter, with the largest showing distinct igneous rims. A variety of textures are displayed by the chondrules, including porphyritic olivine, porphyritic olivine and pyroxene, granular, barred olivine and microcrystalline types. CAIs in the section studied are up to 4 mm in long dimension. Well-developed accretionary rims are present on both CAIs and chondrules. The amount of matrix present in the section studied is approximately 30 to 40%.

Geochemistry: The oxygen isotope composition of the sample plots close to the CCAM line and is consistent with it being a member of the CV group. δ17O = -2.04‰ δ18O = 2.22‰ Δ17O= -3.20‰.
