Antofagasta, Chile

Find: 2017 Feb 21

Classification: HED achondrite (Eucrite, polymict)

History: Found by driving on small hills while meteorite prospecting.

Physical characteristics: Crusted stone. Cut surface reveals light grey interior with darker clasts to 5 mm.

Petrography: (Jérôme Gattacceca, CEREGE) Brecciated igenous rocks with clasts of varied textures (variolitic, subophitic, granulitic) set in a clastic matrix of plagioclase and pyroxene with typical grain size 20 μm. Some pyroxene in the matrix are zoned, others not, others are exsolved. Other minerals: FeNi metal, troilite, chromite, ilmenite, silica polymorph.

Geochemistry: Clastic matrix: low-Ca pyroxene Fs31.2±8.5 Wo1.2-8.2, Fe/Mn=34.2 (N=7), plagioclase An90.5Ab8.8Or0.7 (N=1). Granulitic clasts: low-Ca pyroxene Fs56.0±0.6Wo4.3±0.3, FeO/MnO=31.5, plagioclase An80.0Ab18.8Or1.3 (N=2). Variolitic clasts: low-Ca pyroxene Fs56.9Wo5.0±1.1, FeO/MnO=35.6 (N=3), plagioclase An89.0Ab10.1Or0.9 (N=2).

Classification: eucrite-pmict
