WIKIPEDIA:

Aubritesare a group ofmeteoritesnamed for Aubres,[1]a small achondrite meteorite that fell in 1836 inAubresnearNyons,France. They are primarily composed of theorthopyroxeneenstatiteand are often called enstatiteachondrites. Theirigneousorigin separates them from primitive enstatite achondrites and means they originated in anasteroid.

Comparisons of aubrite spectra to the spectra of asteroids have revealed striking similarities between the aubrite group and theE-type asteroidsof theNysa family. A smallnear-Earth object,3103 Eger, is also often suggested as the parent body of the aubrites.[2]

It has been suggested that aubrites may originate from the planetMercury.[1][3]

Northwest Africa 15304(NWA 15304)

(Northwest Africa)

Purchased: 2022 Feb

Classification: Enstatite achondrite (Aubrite)

History: Purchased in February 2022 from a dealer in Ouargla, Algeria, by an Algerian team represented by David Lehman.

Petrography: (A. Irving,UWSand P. Carpenter,WUSL) Breccia composed of lithic clasts and related crystalline debris in a dark fine grained, partly fluidal matrix (sepia brown and almost opaque in thin section). The mineralogy is dominated by enstatite (exhibiting undulose extinction), which is accompanied by accessory forsterite, diopside, fluororichterite, cristobalite, alabandite, Si-bearing metal (with variable Ni and Si contents), Cr-Ti-troilite and alkali feldspathic glass (confined to the matrix).

Geochemistry: Enstatite (Fs0.0±0.0Wo0.7±0.0, N = 2), forsterite (Fa0.0±0.0, N = 2), diopside (Fs0.0-0.1Wo45.8-44.4, N = 2), fluororichterite kamacite (Ni 5.4 wt.%, Si 0.9 wt.%; Ni 3.1 wt.%, Si 2.0 wt.%; N = 2), Si-rich metal (Ni 2.2 wt.%, Si 8.5 wt.%), Ni-rich metal (Ni 12.7 wt.%, Si 1.4 wt.%).

Classification: Aubrite (melt-matrix breccia, richterite-bearing).

Specimens: 28.5 g including a polished thin section and a polished endcut atUWB; remainder with Mr. D. Lehman.
