Los Vientos 368 (LoV 368)        24º36.427’S, 69º51.355’W

Antofagasta, Chile

Find: 2018 Jan 5

Classification: Ordinary chondrite (LL4-6)

History: Marc Jost found the sample on January 5, 2018, during a meteorite hunt in the Los Vientos dense collection area of the Atacama Desert in Chile.

Physical characteristics: The sample is a complete stone ~50% covered by a dull black, contraction-cracked, flow-lined fusion crust. The surface of the sample has experienced significant wind damage while in residence on the desert pavement. The cut face shows the interior has a brecciated texture composed of chondrules, fresh metal grains and angular clasts.

Petrography: Description and classification (A. Love, App) Sample is a breccia composed of chondrules, fragments and sparse recrystallized lithic clasts set within a clastic host. Chondrules average diameter of 754 μm (n=20). Secondary plagioclase has an average length of 50 μm (n=53). Clinoenstatite is present. Type 4 lithic clasts show distinct chondrules and twinned clinoenstatite in a recrystallized matrix. Type 6 clasts are thoroughly recrystallized and lack chondrules. Additional minerals are: phosphates, ilmenite, chromite, high Ca pyroxene, troilite.

Geochemistry: (A.Love-App) Olivine (Fa28.0±0.5, Fe/Mn=52.5±2.1 n=10); low Ca pyroxene (Fs18.1±5.0Wo0.9±-0.8 (Fs7.6-24.7Wo0.2-2.3), Fe/Mn32.8, n=11).

Classification: Ordinary Chondrite (LL4-6, C-S3, W2). Based on chondrule size, magnetic susceptibility and compositions of olivine and pyroxene, sample is an LL chondrite. Equilibrated olivine and unequilibrated pyroxenes in host and one clast indicate type 4. Recrystallized texture and grainsize of secondary plagioclase in lithic clasts indicate type 6. May be paired with LV360 (found 450 m away).

Specimens: Marc Jost (SJS) holds the main mass. 2 sliced fragments weighing a total of 23.54 g and a polished mount and thin section are on deposit at App.
