Dhofar 1269                        18°43'53''N, 54°30'33''E

Dhofar, Oman

Find: 4 March 2005

Achondrite (diogenite, polymict breccia)

History and Physical characteristics: A dark brown, 42 g stone was found in the Dhofar region of the Sultanate of Oman by E. Olson on March 4, 2005.

Petrography: (T. Bunch and J. Wittke, NAU) A polymict breccia that contains two distinct lithologies: a) coarse-grained orthopyroxene (< 5 mm fragment size), plagioclase, and chromite. b) Partially brecciated gabbro (olivine orthopyroxenite) containing cumulate olivine + orthopyroxene + chromite with plentiful inclusions of FeS. Modal analyses of lithology B made on 4 clasts (vol%): orthopyroxene = 48-65, olivine = 31-49, FeS = 3-5 and chromite = 1.

Mineral compositions and Geochemistry: Lithology A: orthopyroxene (Fs21.9Wo2.8; FeO/MnO = 30, chromite (Cr/(Cr + Al) = 70). Lithology B: orthopyroxene (Fs23.8Wo3.2; FeO/ MnO = 29), olivine (Fa29.1; FeO/MnO = 48), chromite (Cr/(Cr + Al) = 53), FeS (contains 0.45 wt% Zn and 0.38 wt% Ti), metal (2.8 wt% Ni).

Classification: Achondrite (diogenite, polymict breccia); minimal shock and weathering.

Type specimens: An 8.4 g sample is on deposit at NAU. Olson holds the main mass.
