Pallasite, Main Group
A pallasite meteorite found near Esquel, a Patagonian town in the northwest part of the province of Chubut. It is regarded as one of the most beautiful meteorites ever found, due to the beautiful yellowish olivine (peridot) crystals shown in its cut and polished slabs. Olivine (forsterite) has an average composition Fa11.7 (Wasson and Choi, 2003), Fa10.0-Fa14.5 (Shen et al., 2011), or Fa11.56 (McKibbinn et al., 2019). The ∆17O value is -0.25.
There are discrepancies in the value of the recovered mass reported from different sources. According to Giacomelli (1962 and 1969) and The Meteoritical Bulletin no. 29 (1964) the mass, found embedded in the soil and brought to Buenos Aires, weighed "about 1500 kg". However, O. A. Turone, Buenos Aires, claimed a mass weight of 755 kilograms (1,664 lb) in a private communication to J. Koblitz, 1994 (MetBase). Robert Haag, the buyer of the main mass, reported that the original mass was 680 kg and not 1500 kg (Ulff-Møller et al., 1998). Almost all pieces from the Esquel meteorite on the market are cut from his piece.
