Writeup from MB 108:

Laboulaye        34°5.19283’S, 63°23.2655’W

Cordoba, Argentina

Find: prior to 2004

Classification: Ordinary chondrite (H5)

History: Originally found by a farm owner in a field, the main mass was purchased from the finder in Laboulaye in 2004.

Physical characteristics: Consists of two stones, 2674 g and 150 g.

Petrography: (C. Herd and M. Holt, UAb) Optical and microprobe examination of a polished thin section shows well-delineated chondrules of a variety of textural types. Plagioclase grains are approximately 10 to 20 microns in diameter. Metal is largely replaced by oxides, although sulfides are intact. Shock effects include minor veining, and undulatory extinction with >2° angular variation in olivine. Weathering grade according to Zurfluh et al. (2016); shock stage according to Fritz et al. (2017).

Geochemistry: (C. Herd and M. Holt, UAb) Data obtained by EMP examination of carbon-coated thin section: Olivine Fa17.9±0.6 (n=43); Low-Ca Pyroxene Fs16.3±1.0Wo1.3±0.7 (n=35).

Classification: Ordinary chondrite, H5

Specimens: Type specimen of 30.4 g, including one thin section, is at UAb. 2 stones totaling 2794 g with Joshua Earth & Space Museum.
