Writeup from MB 111:

Northwest Africa 14980 (NWA 14980)

(Northwest Africa)

Purchased: 2021 Aug

Classification: HED achondrite (Eucrite, unbrecciated)

History: Purchased by Jason Whitcomb in August 2021 from an Algerian dealer.

Petrography: (A. Irving, UWS and J. Boesenberg, BrownU) This specimen has a coarse gabbroic texture (mean grainsize ~3 mm) and evidence of experiencing moderate shock. Composed of relatively coarse polygranular aggregates of low-Ca pyroxene (some of which is pigeonite with fine augite lamellae) and polycrystalline grains of calcic plagioclase together with accessory chromite, troilite, ilmenite and rare kamacite. Some black shock melt veinlets and veinlets of secondary calcite are present.

Geochemistry: Low-Ca pyroxene (Fs45.9-47.4Wo3.7-5.1, FeO/MnO = 30-31, N = 4), pigeonite (Fs41.8-43.5Wo11.1-8.0, FeO/MnO = 29-32, N = 3), plagioclase (An85.5-88.6Or0.6-0.3, N = 6).

Classification: Eucrite (unbrecciated, gabbroic, moderately shocked).

Specimens: 20.7 g including one polished thin section at PSF; remainder with Mr. J. Whitcomb.
