Writeup from MB 107:

Realicó        35°1’S, 64°19’W

La Pampa, Argentina

Find: 1970

Classification: Ordinary chondrite (L5)

History: The meteorite was found around 1970 by a farmer while plowing a rock-free field in the Realicó area, La Pampa Province, Argentina. The only mass, with a weight of 12 kg approximately, was kept at the farm. This find was little known until 2015, when an amateur astronomer (J.C. Spagnotto, Observatorio El Catalejo de Santa Rosa, La Pampa, Argentina) learned about the meteorite. Spagnotto sent a sample to ICATE and the stone was identified as a chondrite.

Petrography: The stone is highly altered. Different types of chondrules are visible: BO, RP and POP with apparent diameter ranging from 600 microns to 1.5 mm. The shock features record by crystals such as: undulatory extinction, planar fractures, melt pockets and the presence of polycrystalline troilite indicate a state of shock S3 or S4. A strong degree of oxidation of metal suggest an alteration stage W3.

Geochemistry: Mineral composition: EMP analyses, Olivine, Fa25.4±0.5 (n=51); pyroxene, Fs21.1±0.5Wo1.2±0.2 (n=28).

Classification: Ordinary chondrite (L5).

Specimens: Type specimen of 47.5 g is on deposit at the MLP and three thin sections are on deposit at ICATE, Argentina. The main mass remains at the farm.
