Sayh al Uhaymir 562 (SaU 562)        20°59’30.02"N, 57°11’48.33"E

Al Wusta, Oman

Found: 17 Apr 2008

Classification: HED achondrite (Eucrite, unbrecciated)

Physical characteristics: (L Garvie, ASU) Single stone. Lacks fusion crust. Sawn surface shows medium-grained mosaic of approximately equal proportions of anhedral to bladed, white plagioclase (to 3 mm) and honey-brown, anhedral, granular pyroxene (to 1.5 mm) crystals.

Petrography: (Andrew Foreman, Ryan Zeigler, WUSL) The meteorite consists of feldspar and exsolved pyroxene phenocrysts. Very minor olivine present. Accessories include silica, chromite, and ilmenite. Troilite blebs fill some annealed shock fractures within plagioclase. Pigeonite is the original igneous pyroxene, which has subsequently exsolved augite, with parallel exsolution lamellae ranging from very fine (sub-μm to 2 μm width) to coarse (5 μm). Plagioclase 0.5 to 3 mm, and pyroxene 0.5 to 1.5 mm.

Geochemistry: (Andrew Foreman, Ryan Zeigler, WUSL) Feldspar An87.3-88.9Ab10.6-12.2; augite Fs47.6-35.5Wo22.5-32.3, Fe/Mn=27.8-35.6; pigeonite Fs62.7-51.3Wo4.6-14.6, Fe/Mn=25.7-33.5; olivine Fa75.7, Fe/Mn=51.5. INAA of an 84-mg sample gives 20.8% FeO, Sc 25 ppm, Co 4.4 ppm, La 0.87 ppm, Sm 0.93 ppm, Eu 0.54 ppm, and Yb 1.6 ppm. Sr 130±30 ppm, which is very low for a meteorite from Oman.
