Writeup from MB 111:

Northwest Africa 15094 (NWA 15094)

(Northwest Africa)

Purchased: 2021 Sep

Classification: Ordinary chondrite (H4)

History: Purchased by Jason Whitcomb in September 2021 from an Algerian dealer.

Petrography: (A. Irving, UWS and J. Boesenberg, BrownU) Well-formed, relatively small equilibrated chondrules containing devitrified glass occur within a relatively fine-grained ferroan matrix containing very altered kamacite (mostly replaced by Fe oxides), troilite, chromite, chlorapatite and Fe phosphate (possibly secondary given the degree of terrestrial weathering of primary metal), but no plagioclase. This specimen is unusually rich in phosphates.

Geochemistry: Olivine (Fa16.5±0.3, range Fa16.0-16.9, N = 9), low-Ca pyroxene (Fs15.0±0.4Wo1.2±0.1, range Fs14.6-15.7Wo1.1-1.4, N = 6).

Classification: Ordinary chondrite (H4).

Specimens: 21.1 g including one polished thick section at PSF; remainder with Mr. J. Whitcomb.
