Jiddat al Harasis 619 (JaH 619)        19°19.575’N, 55°21.954’E

Zufar, Oman

Found: 16 Feb 2009

Classification: Carbonaceous chondrite (CO3)

History: A single stone was found during a search for meteorites by U. Eggenberger, E. Gnos, E. Janots, F. Zurfluh.

Physical characteristics: Irregularly shaped stone partially covered by fusion crust, mass of 14.54 g.

Petrography: (B. Hofmann, NMBE, F. Zurfluh, E. Gnos, MHNGE): Chondrules with a typical size of 0.2 mm in fine-grained matrix containing magnetite. Refractory inclusions (dominantly gehlenite-rich) are common. Petrographic grade as determined by cathodoluminescence colors is 3.2. There is no significant secondary Fe-enrichment of Mg-poor silicates. Shock grade S1.

Geochemistry: Olivine compositions are Fa0.7-38.6, mean Fa12.5, median Fa2.9 (n=32), pyroxene compositions are Fs0.9-44.6Wo0.3-3.2, mean Fs8.9Wo1.9, median Fs3.5Wo2.0 (n=14). Oxygen isotopes (I.A. Franchi and R.C. Greenwood, OU): Analyses of a bulk sample yielded δ17O = -3.13, δ18O = 1.00, and Δ17O = -3.66 per mil. These values plot on the CCAM line within the CV and CK fields, but also close to another CO (NWA 5247).

Classification: Based on texture and mineralogy this is a CO3.2 carbonaceous chondrite. The oxygen isotopic composition would more likely indicate CV or CK, but these types can be excluded based small size of chondrules.

Specimens: All at NMBE.
