Sayh al Uhaymir 202


Found 2001, January 22 and 2002 January 15

Carbonaceous chondrite (CV3)

A 249.06 g stone and six additional fragments (total 86.80 g) giving a total weight of 335.86 g were found. All fragments fit to one stone and were found by A. Al-Kathiri, B. Hofmann, and E. Gnos. Classification and mineralogy (E. Gnos, UBE; B. Hofmann, NMBE; A. Al-Kathiri, UBE): The rock contains very fine grained CAIs (up to 1.5 mm), fine to medium grained CAIs (up to 3 mm in size), as well as few coarse grained CAIs (up to 15 mm in size). The matrix/(chondrule+aggragate) ratio is 0.43. The mineralogy of the CAIs comprises forsterite, spinel, gehlenite, anorthite, and pyroxene (“fassaite” or Al diopside). The composition of matrix and chondrule olivine is Fa1.8-8.5, and low-Ca pyroxenes show a range of Fs1.8-6.3Wo1.1-1.4. Many normal chondrules contain  well-equilibrated olivine or olivine-orthopyroxene. The rock also contains magnetite, and kamacite. Weathering grade is 2-3, shock stage is 2, and metamorphic grade is 3.2/3.3 based on red cathodoluminescence colors. Probably paired with SaU 040. All specimens NMBE.
