Description from the seller

Northwest Africa 17862 (NWA 17862)
Weight: 1.6 g

Very rare ungrouped achondrite with super fusion crust!

Purchased: May 2025
Tunisia
The meteorite is predominantly composed of augite crystals almost devoid of Fe (about 80% by volume), up to 1.5 mm in size, with less abundant enstatite present as single grains, lamellar exsolution, and small inclusions within the augite. Enstatite often peculiarly encloses the augite, which contains a few small glassy inclusions rich in Si, Al. Accessories include daubréelite, alabandite, and a Mn,Fe oxide phase.

Classification: Ungrouped achondrite, rich in Mg.

Probably related to Ksar Ghilane 022, Northwestern Africa 15915, and Northwestern Africa 13307.
