Writeup from MB 110:

Northwest Africa 14014 (NWA 14014)

(Northwest Africa)

Purchased: 2021

Classification: Primitive achondrite (Winonaite)

History: Purchased by Grant Harkness in 2021 from a Moroccan dealer.

Petrography: (A. Irving, UWS and J. Boesenberg, BrownU) Poikiloblastic texture with larger enstatite oikocrysts enclosing chadacrysts of forsterite accompanied by diopside and tiny rounded inclusions of relatively sodic plagioclase together with accessory stained kamacite, troilite, chlorapatite and chromite.

Geochemistry: Forsterite (Fa4.0-4.2, FeO/MnO = 17-22, N = 4), enstatite (Fs4.5-5.2Wo1.7-1.9, FeO/MnO = 12-16, N = 7), diopside (Fs1.2-2.0Wo44.0-45.3, FeO/MnO = 10-13, N = 5), plagioclase (Ab77.7-78.2An18.9-18.8Or3.4-3.0, N = 2).

Classification: Winonaite. Possibly paired with NWA 13958 and many other recently classified specimens based on essentially identical textures and mineral compositions.

Specimens: 20.9 g including one polished thin section is at PSF; remainder in the Harkness Collection.
