Writeup from MB 104:

Sayh al Uhaymir 564 (SaU 564)        20.528°N, 56.681°E

Al Wusta, Oman

Find: 2011 Feb

Classification: Ordinary chondrite (L3)

History: Found by an anonymous prospector in February 2011.

Petrography: (A. Irving and S. Kuehner, UWS) Unequilibrated chondrite composed of well-formed, mostly medium-sized chondrules (0.4-1.1 mm; some up to 1.5 mm) in a brown stained matrix

Geochemistry: Olivine (Fa2.9-62.5; Cr2O3 in ferroan examples = 0.03-0.08 wt.%, mean 0.05±0.02 wt.%, N = 5), orthopyroxene (Fs0.3-3.7Wo0.4-0.1), pigeonite (Fs20.2Wo8.7), subcalcic augite (Fs9.1Wo31.8). Oxygen isotopes (K. Ziegler, UNM) Analyses of acid-washed subsamples by laser fluorination gave, respectively δ17O 3.562, 3.697; δ18O 4.751, 4.902; Δ17O 1.053, 1.109 per mil.

Classification: Ordinary chondrite (L3). Oxygen isotopes could be consistent with either an L or LL affinity, but chondrule size and magnetic susceptibility favor an L3 designation.

Specimens: Type specimen plus one polished thin section at PSF; main mass with anonymous collector.
