Antofagasta, Chile

Find: 26 Feb 2017

Classification: HED achondrite (Howardite)

History: Found on granodiorite pediment surface by a three-person team.

Physical characteristics: Cut face reveals light-gray interior with darker clasts to 5 mm.

Petrography: (J. Gattacceca, CEREGE) Lithic and mineral clasts (to several mm) set in clastic matrix. Main minerals are low-Ca pyroxene, plagioclase. Other minerals: kamacite, ilmenite, chromite, troilite. Both diogenite (Fs22 to Fs32) and eucrite (Fs38 to Fs66) material is found. Eucrite material abundance is about 20 vol%.
