Limón Verde 008        22°30.07’S, 68°51.74’W

Antofagasta, Chile

Find: 20 Oct 2019

Classification: Carbonaceous chondrite (CK5)

History: The meteorite was found by Mr. M. Nepomiluev during a visual search for meteorites in the Atacama desert.

Physical characteristics: Single stone with pebble-like shape has fractured black fusion crust. Total mass of the stone is 3 g.

Petrography: (C. A. Lorenz, Vernad). The meteorite is composed of recrystallized granular matrix joining the chondrules, chondrule fragments and large mineral grains. The contacts of chondrules and matrix are poorly delineated. The meteorite contains olivine, pyroxene, plagioclase, magnetite, spinel, ilmenite, pentlandite and pyrrhotite. Olivine has weak undulatory optical extinction, irregular and minor planar fractures; magnetite contains fine exsolution lamellae and inclusions of spinel and ilmenite.

Geochemistry: Mineral composition and geochemistry: (T. Kryachko, Technograd, Moscow) Olivine Fa30.9±0.26 (N=17), Ni in olivine is 0.36±0.08 wt%; clinopyroxene En8.16-23.6Wo6.02-45.6; rare low-Ca pyroxene En25.3Wo0.77; magnetite (wt%): Cr 6.38±1.35; Ti 0.40±0.18; Al 2.5±0.27 (N=12).

Classification: CK chondrite of type 5 (CK5), shock stage is S2, weathering index is wi-1.

Specimens: Type specimen of 1.23 g and thin polished section are on deposit in Vernad. Mr. M. Nepomiluev holds the main mass of the meteorite.
