Dar al Gani 881

Libya

Found 2000 November

Achondrite (howardite)

A crusted stone of 86 g was found by a private collector in the Dar al Gani desert. Mineralogy and classification (A. Burroni and L. Folco, MNA-SI): polymict breccia; clasts (up to several mm in size) interspersed in a fragmental matrix include: 1) fine-grained basaltic eucritic clasts; 2) medium-grained cumulate eucritic clasts (mostly pigeonite En₅₈Wo₆ and calcic plagioclase); 3) dark, quench-textured clasts with microporphyritic pigeonite crystals set in cryptocrystalline or glassy matrix; 4) large (up to 1.5 mm in size) single-crystal fragments of low-Ca pyroxene of diogenitic origin (En₇₀Wo₃). The rock is cross-cut by discrete shock melt veinlets up to 0.25 mm thick. DaG 881 is possibly paired with DaG 923 [sic; probably was supposed to be DaG 915 - Ed. 29 Jun 2007] and DaG 932. Specimens: type specimen, 17.6 g, and thin section MNA-SI; main mass with anonymous finder
