Sayh al Uhaymir 449                       21°2.4'N, 57°18.9'E

Oman

Find: 19 March 2006

Lunar (feldspathic impact-melt breccia)

History: This meteorite was found on a limestone plateau in the Dhofar desert of Oman, far from any other known lunar meteorites.

Physical characteristics: A single brownish to dark green stone weighing 16.5 g, with no fusion crust.

Petrography: (M. A. Ivanova and M. A. Nazarov, Vernad) The meteorite is a clast-rich impact-melt breccia containing numerous mineral fragments and lithic clasts embedded in a fine-grained impact-melt matrix. The lithic clast population is dominated by impact-melt breccias of anorthositic, gabbroic, and noritic compositions. The size range of the clasts is 0.01-10 mm, and the main minerals are pyroxene, feldspar, and minor olivine, silica, chromite, ilmenite, Ca phosphate, troilite and FeNi metal.

Mineral composition and Geochemistry: (M. A. Ivanova and N. N. Kononkova, Vernad.) Feldspar (An93.4-97.4Ab2.5-9.2), clinopyroxene (En6.5-71.1Wo5.1-44.1; Fe/Mn = 61), orthopyroxene (En53.2-79.5Wo3.3-4.7; Fe/Mn = 59); olivine (Fo50.5-76.7; Fe/Mn = 96), ilmenite (MgO = 3.6 wt%). Average glassy matrix composition: SiO2 = 46.2, TiO2 = 0.33, Al2O3 = 25.6, FeO = 5.80, MgO = 4.85, CaO = 15.33, Na2O = 0.38 (all in wt%).

Classification: Lunar (feldspathic impact melt breccia); minor weathering, Fe hydroxides are present. Specimens: A type specimen of 3.6 g and one thin section are on deposit at Vernad. An anonymous finder holds the main mass of the meteorite.
