Writeup from MB 105:

Northwest Africa 10884 (NWA 10884)


Purchased: 20 May 2013

Classification: Ordinary chondrite (H5)

History: Purchased via eBay from GHupé/Nature’s Vault on May 20, 2013. Seller said sample was found in Morocco in 2012. Material for classification donated to Cascadia.

Physical characteristics: Already cut face has heavily stained brown interior and exterior. Some metal visible.

Petrography: Consists of readily distinguished chondrules set in a largely transparent matrix, crosscut by numerous weathering veins. Olivine shows undulatory extinction with only a few grains displaying a single set of planar fractures. Troilite, minor metal, and grain-shaped patches of iron-bearing weathering product (~65% of total opaques) make up approximately 15% of the thin section.

Geochemistry: Olivine (Fa19.4±1.4, N = 33), low-Ca pyroxene (Fs16.7±0.8Wo1.4±0.32, N = 18), high-Ca pyroxene (Fs6.7±1.4Wo 46.8±2.0, N = 12).

Specimens: Cascadia holds 96.3 g in several pieces, a polished thin section, and a mounted butt. John Shea holds the main mass.
