Pallasites are easily the most beautiful meteorites, especially when cut and polished.
When etched, the metal phase may exhibit a Widmanstatten pattern. Pallasites are considered to be the result of mixing between solid silicate mantle and liquid metal core at the core-mantle boundary of a fully differentiated parent body. This mineralogy is consistent with complete differentiation of a chondritic asteroid, leaving only olivine in the silicate residue at the core-mantle boundary. Eagle Station trio Pallasite have mineralogy similar to that main group Pallasite.
