Writeup from MB 102:

Dhofar 1758 (Dho 1758)        18°42’50.5"N, 54°20’53.5"E

Zufar, Oman

Found: Jan 2011

Classification: Ordinary chondrite (H4-6)

Petrography: (C. Hayes, UAb) Thin section reveals two distinct textures of different petrologic type: one with high matrix-chondrule ratio and another with well-defined chondrules. Variability in low-Ca pyroxene data obtained from the latter area suggests petrologic type 4. A type 4-6 breccia.

Geochemistry: (C. Herd and C. Hayes, UAb) Olivine Fa19.0±0.8 (n=36); Low-Ca Pyroxene Fs17.4±1.7Wo1.3±0.5 (n=13). Olivine data was from both textural areas whereas low-Ca pyroxene data was obtained from the area with well-defined chondrules.

Classification: Ordinary chondrite (H4-6), breccia.

Specimens: 39.1 g type specimen on deposit at UAb. Main mass, including thin section, at SQU.
