Writeup from MB 105:
Northwest Africa 10796 (NWA 10796) (Northwest Africa) Purchased: 2016 Jan Classification: Carbonaceous chondrite (CK3/4) History: Purchased by Matéo Made Météor Gonzales in January 2016 from a dealer in Ouarzazate, Morocco. Petrography: (A. Irving and S. Kuehner, UWS) Irregularly shaped, separated chondrules (apparent diameter 600±400 μm) containing Cr-magnetite plus sparse fine grained CAI are set in a fine grained, reddish-brown matrix containing intermediate plagioclase, Cr-magnetite (altered to Fe hydroxides) and Ni-bearing troilite. Highly magnesian cores are present in some olivine grains. Geochemistry: Olivine (Fa1.3-33.0, N = 3), orthopyroxene (Fs3.2-16.0Wo1.3-1.0, N = 3), clinopyroxene (Fs1.5Wo40.4; Fs11.9Wo48.5; N = 2). Semi-quantitative EDS spectra show that magnetite contain minor amount of Cr at levels typical for CK chondrites. Classification: Carbonaceous chondrite (CK3/4). Specimens: 10.33 g including one polished thin section at UWB; remainder with Mr. M. Gonzales. | ||||||||||||||||||||||||||||||
