Writeup from MB 111:

Northwest Africa 15363 (NWA 15363)

(Northwest Africa)

Purchased: 2022 Apr

Classification: Rumuruti chondrite (R3)

History: Purchased by Ziyao Wang in January 2019 from a dealer in Guelmim, Morocco, and sold to Fujun Ren in April 2022.

Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Well-formed chondrules (apparent diameter 620±250 µm, N = 25) and rare very fine grained CAI are set in a fresh matrix (~40 vol.%, opaque in thin section) containing pyrrhotite, pentlandite and medium-Ti chromite. Metal is absent. A lithic clast (3.5 mm across) with triple grain junction texture is present in the studied thin section. A ~1 μm spherule of elemental bismuth was found in one pyrrhotite grain.

Geochemistry: Olivine (Fa26.2±15.6, range Fa0.2-41.0, N = 10), low-Ca pyroxene (Fs14.1±5.8Wo0.9±0.4, range Fs8.3-19.5Wo0.4-1.4, N = 4), subcalcic augite (Fs15.8Wo25.4; Fs12.5Wo33.1; N = 2), augite (Fs17.1Wo40.6).

Classification: R3 chondrite.

Specimens: 25.3 g including one polished thin section at UWB; remainder with Fujun Ren.
