Writeup from MB 104:

Jiddat al Harasis 874 (JaH 874)        19°58.897’N, 56°25.0’E

Al Wusta, Oman

Found: 2007 Mar 10

Classification: Rumuruti chondrite (R5)

History: A small, dark-brownish colored individual lacking any fusion crust was recovered from the Arabian Desert, Oman.

Petrography: The meteorite is composed of readily delineated chondrules set into an olivine-rich brecciated matrix. Olivine, Ca-pyroxene and rare orthopyroxenes are equilibrated in chondrules as well as in the matrix. Albitic feldspar shows wide compostional range and typically ocurrs in 10-40 μm sized patches. Opaque phases are sulfides; metal is virtually absent.

Geochemistry: Olivine, Fa38.2±0.3 (Fa37.7-38.8, n=15); Ca-pyroxene, Fs11.1±0.7Wo45±1.1 (Fs10.2-12.9, n=21); low-Ca pyroxene, Fs29.7Wo1; plagioclase, An7.6-15.9Ab79.2-87.6Or3.3-6.8 (n=27)
