Dhofar 735

Oman

Found 2002 November 9

Carbonaceous chondrite (CM2)

Two stones weighing 304 g and 77 g were found on November 2002 in the Dhofar region of Oman. Mineralogy and classification (M. Ivanova, Vernad; L. Taylor, UTenn): fusion crust is present, the meteorite consists of altered chondrules, sometimes with a halo around, olivine aggregates, and fragments of matrix material set within a phyllosilicate matrix. Olivine, Fa0.3–22, CaO 0.35 wt%, Cr2O3 0.28 wt%. No orthopyroxene is present. Refractory inclusions are rare and consist of anorthite, Al-rich pyroxene and forsterite. The minor phases are kamacite, taenite, and tetrataenite (Ni, up to 60 wt%), troilite, rare pentlandite, chromite, Mg-ilmenite, schreibersite, and Ca-carbonates. The matrix is composed mainly of serpentine. Tochilinite was not found. Weathering grade is W1. Oxygen isotope composition is in the range of metamorphosed CM chondrites (R. N. Clayton, UChi): δ18O = +21.99‰; δ17O = +10.85‰; ∆17O = –0.58‰. Specimens: a type specimen of 58.8 g and a thin section, Vernad; main mass with anonymous finder.
