Writeup from MB 109:

Northwest Africa 13294 (NWA 13294)

(Northwest Africa)

Purchased: 2018

Classification: HED achondrite (Eucrite)

History: Purchased by Shawn Kashay in 2018 from Mustapha Hnini in Algeria.

Physical characteristics: Single stone with minor fusion crust.

Petrography: (D. Sheikh, FSU) Sample is a fine-grained eucrite containing low-calcium pyroxene, pigeonite, augite, calcic plagioclase, silica glass, Si-Al-Ca rich glass, and ilmenite. Minor secondary calcite weathering veins present.

Geochemistry: Low-Ca pyroxene (Fs60.7±1.9Wo2.6±0.8, range Fs58.1-64.6Wo1.3-4.1, FeO/MnO=30±2, n=16); pigeonite (Fs53.2±3.1Wo12.1±3.0, range Fs48.1-56.7Wo7.6-17.2, FeO/MnO=31±4, n=9); augite (Fs28.7±4.6Wo38.7±3.7, range Fs23.3-34.9Wo31.4-42.2, FeO/MnO=30±3, n=8); calcic plagioclase (An89.8±2.4, range An85.8-96.7, n=26).

Classification: HED achondrite (Eucrite)

Specimens: 5.35 grams at UCLA; main mass with Shawn Kashay.
