Sayh al Uhaymir 290                     21°04'31.6" N, 57°08'49.3" E

Oman, Al Wusta

Found 2004 Feb. 13th and Nov. 6th

Carbonaceous chondrite (CH3)

History: Sixty-four fragments were discovered within a distance of ~ 10 m by Rainer and Claudia Bartoschewitz during a natural science expedition on a gravel plateau of Miocene fresh-water limestone of Middle Fars group about 35 km SSW of Ghaba Resthouse (Adam County).

Physical characteristics:  Sixty-four fragments weighing between 0.2 to 888 g amount to a total of 1.796 kg.

Petrography:  The meteorite is mostly composed of small chondrules (<20 μm) of various textural types, ~15% fine grained metal, few small "matrix lumps" and rare refractory inclusions.

Mineral composition and geochemistry: (R. Bartoschewitz, Bart., P. Appel and B. Mader, Kiel, M.I. Prudêncio, ITN,  U. Krähenbühl, Bern) Pyroxene (Fs3.99-5.16Wo3.01-1.80, Al2O3 = 1.90, Cr2O3 = 0.62 [wt%]), Ti-rich pyroxene (Fs2.88 Wo19.66, Al2O3 = 10.40, Cr2O3 = 1.27 [wt%]), olivine (Fa1.88-0.83, CaO = 0.43 - 0.27, Al2O3 = 0.27, Cr2O3 = 0.47 [all wt%]), sulfide (Ni = 0.4-21.7 wt%), kamacite (Ni = 3.7-8.0, Co = 0.35-0.56, Si = 0.02-0.15, Cr = 0.08-0.40 [all wt%]), tetrataenite (Ni = 59.2, Co = 1.45 [wt%]). Whole rock siderophile, chalcophile and lithophile element abundances similar to other CHs. Magnetic susceptibility = log χ = 5.2 x 10-9 m3/kg. Noble gas isotopes (J. Park and K. Nagao, UTokE, Japan, R. Okazaki, KyuU) high concentrations of solar noble gases. O isotopes (M. Kusakabe, OkaU) δ17O = 1.91‰, δ18O = 5.71‰.

Classification:  Carbonaceous chondrite (CH3) moderate weathering.

Type specimens: A total of 20.1 g are on deposit at UTokE. Bart holds 1500 g and one thin section.
