Writeup from MB 104:

Dhofar 1988 (Dho 1988)        19°4.865’N, 54°46.024’E

Zufar, Oman

Find: 2011 Dec 2

Classification: Carbonaceous chondrite (C2, ungrouped)

History: The meteorite was found 2011 during a field trip in the Oman desert.

Physical characteristics: Small almost black stone partly covered with fusion crust.

Petrography: The meteorite is a breccia displaying an dark gray to black interior. It is composed of relatively large chondrule pseudomorphs (mean 550 μm in diameter) and rare isolated mineral grains set into an abundant matrix of phyllosilicates, Ca-carbonate, and pyrrhotite. Chondrule pseudomorphs are typically surrounded by fine-grained accretionary rims. Anhydrous silicates are almost exclusively forsteritic olivine. Very rarely more Fe-rich olivine (up to Fa26) has been encountered; no pyroxene was found.

Geochemistry: Oxygen isotopes (K. Ziegler, UNM): acid-washed material analyzed in replicate by laser fluorination gave, respectively: δ18O=16.424, 21.864, 20.095; δ17O=7.032, 10.751, 9.582; Δ17O= -1.64, -0.793, -1.028 (all per mil).

Classification: Oxygen isotopes plot close to Tagish Lake (C2-ungrouped), between CI and the ungrouped C2 chondrites Y86720, Y82162 and B7904.
