Writeup from MB 107:

Northwest Africa 11589 (NWA 11589)

(Northwest Africa)

Purchased: 2017

Classification: Carbonaceous chondrite (CV3)

Physical characteristics: Dark stone. Cut surface reveals a dark-gray interior with mm-sized chondrules and CAIs.

Petrography: (J. Gattacceca, H. Pourkhorsandi, CEREGE ; Lydie Bonal, IPAG) Chondrules (average apparent diameter 1.1 mm, N=18), mostly of type I, and CAIs set in a fine-grained iron-rich matrix. Main opaque minerals are troilite and metal. Based on the structural order of the polyaromatic matter assessed by Raman spectroscopy, this meteorite appears to be as metamorphosed as Axtell (3.6/3.7). The Raman spectroscopy parameters of interest are  FWHM-D (cm-1)=69.2±4.0, ID/IG=1.41±0.06 (see Bonal et al. 2006, GCA 70:1849-1863, figure 4).

Geochemistry: Olivine Fa10.0±10.5, PMD 68% (N=11). Orthopyroxene Fs1.2±0.4Wo0.9±0.1 (N=2). Magnetic susceptibility log χ (× 10-9 m3/kg) = 3.91.

Classification: Carbonaceous chondrite (CV3, reduced subgroup). Estimated subtype 3.6/3.7.

Specimens: Type specimen at CEREGE. Main mass with Kuntz.
