Los Vientos 360 (LoV 360) 24°36.28’S, 69°51.37’W Antofagasta, Chile Find: 2018 Jan 25 Classification: Ordinary chondrite (LL4-6) History: Marc Jost found two large pieces and several smaller fragments within 1 m2 area while hunting for meteorites on the desert pavement in the Atacama Desert. The total known weight of the samples collected is 277.5 g. Physical characteristics: Fragments have rounded, irregularly shaped exteriors showing dark brown contraction-cracked fusion crust. Some fragments contain an orange coating of caliche. The cut face of the type specimen shows the sample has a light-colored, brecciated texture composed of a few chondrules, fragments and angular clasts. Petrography: Description and classification (A. Love, App) Sample is a breccia composed of mm-sized, angular-sub-rounded clasts set within a host of poorly equilibrated chondrules and related mineral debris. Clasts show show a range of petrologic types from 4-6 in addition to a vitrophyric impact melt clast. Chondrules within the type 4 clast contain clinoenstatite and some show sulfide rims. Secondary plagioclase in recrystallized clasts has an average grainsize of 77 μm, n=14. Geochemistry: (A.Love-App): Olivine (Fa27.7±0.8, Fe/Mn=54.0±0.8 n=8); low Ca pyroxene Fs16.1±7.4Wo 0.9±0.6 (Fs7.2-24.8Wo0.5-1.5, n=8). Classification: Ordinary chondrite (LL4-6, C-S3 W1). LL chondrite based on olivine and pyroxene compositions, chondrule diameter and magnetic susceptibility. Clasts of type 4 based on poorly equilibrated compositions of pyroxenes and type 6 based on recrystallized textures and size of secondary plagioclase. Specimens: Marc Jost (SJS) holds the main masses. Several fragments and an end cut weighing 25.57 g and a polished thin section are on deposit at App. | ||||||||||||||||||||||||||||||||||||||
