Los Vientos 290 (LoV 290) 24°38’0.9’’S, 69°53’37.9’’W

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 (Fs₂₂to Fs₃₂) and eucrite (Fs₃₈to Fs₆₆) material is found. Eucrite material abundance is about 20 vol%.

Geochemistry: Overall low-Ca pyroxene Fs_32.5±9.7Wo_2.8±1.4, FeO/MnO=33.0±5.1 (n=18). Diogenite low-Ca pyroxene Fs_26.6±3.7Wo_2.2±0.9(n=12). Eucrite low-Ca pyroxene Fs_44.3±6.6Wo_4.1±1.4(n=6). Plagioclase An_85.7±6.9Ab_13.4±6.3Or_0.9±0.8(n=6), range An_75.7-93.3.Eucrite opthitic lithic clast: low-Ca pyroxene Fs_65.7Wo_2.9(n=1), plagioclase An_90.1±1.4Ab_9.4±1.4Or_0.5±0.0(n=4).
