Writeup from MB 105:

Northwest Africa 10563 (NWA 10563)

(Northwest Africa)

Purchased: 2015 Nov

Classification: Carbonaceous chondrite (CK4)

History: Purchased by Bob Falls in November 2015 from a dealer in Zagora, Morocco.

Petrography: (A. Irving and S. Kuehner, UWS) Separated, well-formed granular chondrules (apparent diameter 1.3±1.0 mm; some with concentric dust rims) containing Cr-magnetite are set in a finer matrix containing Cr-magnetite and intermediate plagioclase. The studied thin section contains an inclusion (7 mm across) composed mainly of aluminous orthopyroxene and calcic bytownite (zoned to oligoclase rim) plus accessory olivine, K-feldspar and composite grains of magnetite (Ti- and Cr-free) with ilmenite.

Geochemistry: Olivine (Fa29.4-29.7, FeO/MnO = 95-105, N = 3), orthopyroxene (Fs25.1-25.2Wo2.6-0.6, N = 3), clinopyroxene (Fs10.8-14.7Wo46.1-47.0, N = 2). Orthopyroxene in inclusion (Fs26.8Wo0.5, Al2O3 = 5.1 wt.%), plagioclase in inclusion (core An89.8Or0.1, rim An25.9Or9.1).

Classification: Carbonaceous chondrite (CK4).

Specimens: 26.4 g including one polished thin section at UWB; remainder with Mr. R. Falls.
