Northwest Africa 4482

Algeria

Find: August 2006

Pallasite (main group)

History: G. Hupé purchased the sample in August 2006 in Tagounite, Morocco.

Physical characteristics: The meteorite consists of a total of 30 dark, magnetic fragments containing yellowish-green silicate in a dark brown matrix.The fragments have a combined weight of 5816 g.

Petrography: (A. Irving and S. Kuehner, UWS) Large olivine grains (up to 8 mm across) with interstitial, porous, banded iron hydroxides enclosing sparse angular grains of terrestrial quartz, and accessory chromite, schreibersite and fresh metal (both kamacite and taenite).

Mineral compositions and geochemistry: Olivine (Fa12.2-13.0, FeO/MnO = 41.1-42.5). Oxygen Isotopes: (D. Rumble, CIW) analysis of acid-washed handpicked olivine by laser fluorination gave δ18O = 3.65, δ17O = 1.72, Δ17O = -0.198(all in ‰).

Classification: Pallasite (main group). The original metal in this specimen is almost entirely weathered to iron hydroxides.

Specimens: A total of 20.1 g of sample, one polished thin section and one polished mount are on deposit at UWS. GHupé holds the main mass.
