Writeup from MB 105:

Dhofar 2046 (Dho 2046)        18°21’24.4"N, 54°11’14.4"E

Zufar, Oman

Find: 2011 Mar 13

Classification: Carbonaceous chondrite (CM2, anomalous)

Physical characteristics: A single black stone. Cut surface reveal homogeneous black interior.

Petrography: Chondrules (mostly olivine-rich), chondrule fragments and olivine fragments (20 vol%) in a fine-grained iron-rich matrix (80 vol%). Average chondrule diameter 240±130 μm (N=25). Chondrules have fine-grained dust mantles. FeNi + FeS grains to 50 μm are found in the matrix and in the chondrules.

Geochemistry: Olivine Fa15.2±24.2 (Fa0.5-76.7, median Fa1.4, PMD=90%, N=9). Oxygen isotopic composition (J. Gattacceca, C. Sonzogni, CEREGE) is δ17O=7.78 ‰, δ18O=19.93 ‰ (analysis of one acid-washed 1.5 mg aliquot of a powdered 200 mg bulk sample). Magnetic susceptiblity log χ (× 10-9 m3/kg) = 4.05.

Classification: CM2-anomalous. The oxygen isotopic composition is anomalous compared to most CM chondrites. The meteorite is possibly paired with Dhofar 225 that has the same oxygen isotopic composition and was found nearby.

Specimens: Type specimen and polished section at CEREGE. Main mass with anonymous finder.
