Writeup from MB 110:

Northwest Africa 14089 (NWA 14089)

Algeria

Find: 2020

Classification: HED achondrite (Eucrite)

History: Acquired by Daniel Sheikh from Aziz Zad in June 2021.

Physical characteristics: Single stone with dark brown fusion crust.

Petrography: (D. Sheikh, Cascadia) Specimen is composed of angular to sub-rounded clasts and elongate grains made up primarily of plagioclase and pyroxene (up to ~1.5 mm) and set within a finer-grained matrix containing accessory SiO2-rich glass and ilmenite.

Geochemistry: Low-Ca Pyroxene (Fs52.5±1.3 Wo3.4±1.3, range Fs50.2-55.8Wo1.7-5.5, Fe/Mn=31±3, n=18), Pigeonite (Fs44.7±4.4Wo16.0±5.9, range Fs37.9-51.7 Wo7.0-23.4, Fe/Mn=31±5, n=18), Augite (Fs29.1±4.3 Wo34.8±5.4, range Fs21.1-37.7Wo25.1-43.8, Fe/Mn=29±4, n=25), Calcic Plagioclase (An84.9±2.6, range An80.0-89.8, n=42).

Classification: Achondrite (Eucrite).

Specimens: 43 grams at Cascadia, main mass with D. Sheikh.
