Los Vientos 364 (LoV 364) 24º40.108’S, 69º53.504’W Antofagasta, Chile Find: 2019 Feb 1 Classification: HED achondrite (Eucrite) History: Marc Jost found the 180 g sample on February 1, 2019, while he was hunting for meteorites on the desert pavement in Los Vientos dense collection area of the Atacama Desert in Chile. Physical characteristics: Sample is a broken stone ~50% covered by a wind ablated brownish fusion crust. The fusion crust, where present, is still shiny and shows some relict flow lines and a faint roll-over lip from flight orientation. The cut face shows the interior is a breccia dominated by granular material with a couple of fine-grained clasts and a larger clast with a recrystallized texture. Petrography: Description and classification (A. Love, App) Sample is a recrystallized breccia composed of coarse-grained (~1000µm), subophitic gabbro and finer-grained (~500 µm) basaltic clasts set within a recrystallized matrix of related mineral debris. Pyroxenes are exsolved and share 120º grain boundaries with adjacent grains. Additional minerals are: plagioclase, a SiO2 polymorph, ilmenite and chromite. Geochemistry: (A. Love, App) Pigeonite (Fs58.7±0.2Wo6.2±0.6, Fe/Mn=30.7±0.3, Mg#37.3±0.2, n=8); high Ca pyroxene (Fs29.7±0.4Wo41.7±0.4, Fe/Mn=31.6±0.7, n=8); plagioclase (An91.3±0.3Or0.3±0.0, n=6). Classification: HED Achondrite (recrystallized basaltic and gabbroic eucrite breccia). Based on mineral compositions, Fe/Mn ratios and Mg#’s, this sample is composed of equilibrated basaltic eucrite clasts. Textures and grainsizes indicate this is a recrystallized breccia. Low weathering, low shock. Specimens: Marc Jost (SJS) holds the main mass. A fusion-crusted endcut and partial slice weighing 20.88g and a polished thin section are on deposit at App. | ||||||||||||||||||||||||||||||||||||
