Sayh al Uhaymir 406                   20°03.848N, 56°32.034E

Oman

Find: 10 February 2005

Achondrite (eucrite)

History: S. Bartels, J. Bühler, B. Hofmann, I. Leya, and S. Lorenzetti recovered a single sample during a systematic search for meteorites.

Physical characteristics: Platy rounded stone with minor remnants of fusion crust, 30.917 g.

Petrography: (E. Gnos, UBE; B. Hofmann, NMBE; A. Al-Kathiri, UBE) The rock contains up to 4 mm size rock fragments. It consists of (in vol%): angular volcanic clasts = 8.0; plutonic clasts = 6.6, 7.0% breccia clasts; mineral clasts (predominantly orthopyroxene, pigeonite and augite, minor plagioclase (An78.7–93.7Or0.3–1.6), silica, chromite, troilite, Fe,Ni metal, and ilmenite) = 53.6; myrmekitic orthopyroxene-troilite clasts = 3.3; fine-grained matrix = 16.3. Metal and troilite show minor weathering only.

Mineral compositions and geochemistry: Orthopyroxenes (Fs12.8–31.5En64.1–86.8Wo0.4–4.4), pigeonites (Fs32.4–55.0En37.5–61.1 Wo6.5–14.9), and augites (Fs27.4–41.5En36.1–44.7Wo20.9–33.2). Bulk composition: MgO = 13.75, CaO = 7.94 (both wt%); Fe/Mn= 34.1, Sc = 22, Sm = 1.08 (both ppm).

Classification: Achondrite (eucrite, polymict); S4.

Type specimen: The sample is on deposit at NMBE.
