Name:

The acronym PES was proposed by Wasson and Choi (2003) in substitution of the previously used EST and ESP.

A grouplet named for a pallasite that was found near Eagle Station, Kentucky, in 1880. They all contain highly fragmented olivines, intermixed with small, irregular olivine splinters, in a nickel-iron matrix. Although their mineral assemblage is similar to PMG pallasites, they have different metal and olivine (forsterite) compositions. In fact, the mean Ni content of the metal is higher, and olivine Fa contents are slightly higher (≈Fa20) than those in the Zaisho (Fa18.3), which has the highest Fa among PMG. The O-isotope composition of their olivine (forsterite) is a main parameter to separate the Eagle-Station pallasites (PES) and main-group pallasites (PMG). The mean PMG ∆¹⁷O (=δ¹⁷O-0.52·δ¹⁸O) value is -0.28 ± 0.06‰. The mean PES ∆¹⁷O value is much lower, ≈-4.6‰.
