Writeup from MB 91:

Northwest Africa 960

Morocco

Find: December 2001

Ordinary chondrite (type 3)

History: Purchased in December 2001 by A. and G. Hupé from a Moroccan dealer in Erfoud, Morocco.

Physical characteristics: A single dark brown stone weighing 997 g.

Petrography: (A. Irving and S. Kuehner, UWS; M. Zolensky, JSC) Very chondrule-rich (~80 vol%), with a brown oxidized matrix. Most chondrules (up to 3 mm in diameter, though most below 1 mm) are olivine-rich but some contain low-Ca pyroxenes. Minor magnetite, troilite, pentlandite, chromite, and glass are also present. No metal was observed.

Mineral compositions and geochemistry: Olivine (Fa2–29; peak at Fa2–3, average Fa9.63), low-Ca pyroxene (Fs2–34; peak at Fs2–3, average Fs10.46). Oxygen isotopes: (D. Rumble, CIW) Laser fluorination of whole rock samples (all reported as ‰); δ18O = 6.03, 6.04, 6.18; δ17O = 3.74, 3.78, 3.83; Δ17O = +0.559, +0.592, +0.567.

Classification: Ordinary chondrite (type 3); S1, W1–2. Although the Δ17O values are near those for H chondrites, the δ18O values are much higher and the mineral composition suggests this specimen is very different from H chondrites.

Type specimen: A total of 23 g of sample and one polished thin section are on deposit at UWS. G. Hupé holds the main mass.
