Writeup from MB 105:
Northwest Africa 10834 (NWA 10834) (Northwest Africa) Purchased: 2016 July Classification: Carbonaceous chondrite (CM1/2) History: Purchased by Darryl Pitt in July 2016 from Aziz Habibi in Agadir, Morocco. Petrography: (A. Irving and S. Kuehner, UWS) Very small (apparent diameter 150±50 μm), mostly serpentinized chondrules (some with remnant forsteritic olivine grain cores) and tiny mafic silicate mineral grains occur within a very dark matrix containing irregular shrinkage cracks. Other phases identified include pyrrhotite, Ni-bearing pyrrhotite, pentlandite, Ni-poor kamacite and Mn-Fe-bearing dolomite. Geochemistry: Olivine (Fa0.5-0.6, N = 3). Oxygen isotopes (K. Ziegler, UNM): analysis of a clean sample (unwashed, not pre-fluorinated) by laser fluorination gave, respectively, δ17O = 3.282; δ18O = 10.797; Δ17O = -2.419 per mil. Classification: Carbonaceous chondrite (CM1/2). Specimens: 14.9 g including one polished thin section and one polished thick section at UWB; remainder with DPitt. | ||||||||||||||||||||||||||
