Writeup from MB 93:

Dhofar 1430 18°34'10''N, 54°14'24''E

Dhofar, Oman

Find: 6 March 2006

Carbonaceous chondrite (CK3)

History and Physical characteristics: A 185 g complete, poorly crusted stone was found in the Dhofar region of the Sultanate of Oman by MFarmer and R. Ward on March 6, 2006.

Petrography: (J. Wittke and T. Bunch, NAU) Greenish gray stone that has a poorly crystallized matrix of olivine, augite, plagioclase, feldspathic glasses, orthopyroxene, Cr magnetite, ilmenite, pyrite, pyrrhotite, and pentlandite. Contains many heavily mantled chondrules (up to 1.4 mm in diameter), compound chondrules, relict dusty olivine grains within porphyritic chondrules, single crystals of zoned olivine (0.3-0.85 mm in diameter) and poorly crystallized, plagioclase-rich objects.

Mineral compositions and Geochemistry: Matrix olivine (Fa_29.3-34.5, NiO = 0.78 wt%, FeO/MnO = 95-133); orthopyroxene (Fs_23.3Wo_2.3); augite (Fs₁₂Wo_24.3); plagioclase/ feldspathic glasses (An38-78) and Cr-magnetite (Cr₂O₃ = up to 6.6 wt%).

Classification: Carbonaceous chondrite (CK3), minor shock, minor to moderate weathering.

Type specimens: A sample of 20.1 g is on deposit at NAU. RWard holds the main mass.

Submitted by: Ted Bunch, NAU.
