Writeup from MB 104:
Northwest Africa 7810 (NWA 7810) (Northwest Africa) Purchased: Feb 2013 Classification: Carbonaceous chondrite (CV3) Physical characteristics: Many weathering veins were observed throughout the stone; metal is nearly absent and has been replaced almost entirely by oxides. A few opaque-rich chondrules contain terrestrial oxides. Fine sulfide grains are present in the matrix and in a few chondrules. Weathering is equivalent to W4; the stone is moderately to heavily weathered. Fusion crust is patchy, but present on all sides. Petrography: (A.E. Rubin, UCLA) A fine-grained, fluffy type-A CAI measuring 800 × 910 µm was observed in the thin section. It contains 10-30 μm spinels. One particularly large amoeboid olivine inclusion present in thin section (5 × 3 mm), large for CV3. Several others 0.8 to 2 mm are present. Most chondrules are type I with igneous rims, average diameter ~750 μm. Heterogeneity of olivine and polysythetically twinned low-Ca clinopyroxene are indicative of an unequilibrated chondrite. | ||||||||||||||||||||||||||||||
