Writeup from MB 107:
Sayh al Uhaymir 606 (SaU 606) 20°20.555’N, 56°49.427’E Al Wusta, Oman Find: 12.02.17 Classification: Ordinary chondrite (H5) History: A complete, fresh-looking individual was found during a search for meteorites on February 12, 2017. The area (to a distance of 1-2 km) was searched again in February 2018 but no paired meteorites were found. Physical characteristics: Complete individual fully covered with black, slightly crackled fusion crust. Bulk density based on a shape model is 3.43 g/cm3. Petrography: (Å. Rosén, Bern, E. Gnos, MHNGE, B. Hofmann, NMBE) The meteorite shows a brecciated chondritic texture with well-preserved chondrules. Minor and accessory minerals include chromite, ilmenite and native copper. Typical grain size of plagioclase is 10-20 μm. Mean chondrule size is 0.47±0.21 mm (n=128). Minor rust staining in silicates close to metal grains. Iron hydroxide rims around metal reach up to 20 μm. Geochemistry: (Å. Rosén, Bern and B. Hofmann, NMBE) Olivine compositions are Fa18.1±0.3 (n=48), pyroxene compositions are Fs16.3±0.4, Wo0.9±0.2 (n=29). Cosmogenic radionuclides: (Å. Rosén, GeMSE): Gamma-spectroscopy performed in April 2017 showed detectable activities of short-lived radionuclides indicating decay during ~5 years. At end of measurement, 26Al was 39.1(+4.2,-3.8), 22Na was 17.9(+2.7,-1.3) and 54Mn was 1.1(+0.3,-0.2) dpm/kg. Classification: Based on mineral compositions and mean chondrule size this is an equilibrated H5 chondrite. Cosmogenic isotope data indicate a fall around the year 2012.
