Abstract The silicate phases of 11 pallasites were analyzed instrumentally
to determine the concentrations of some major, minor, and
trace elements. The silicate phases were found to contain about
98% olivine with 1 to 2% accessory minerals such as lawrencite,
schreibersite, troilite, chromite, and farringtonite present. The
trace element concentrations, except Sc and Mn, were found to be
extremely low and were found primarily in the accessory phases
rather than in the pure olivine. An unusual bimodal Mn distribution
was noted in the pallasites, and Eagle Station had a chondritic normalized
REE pattern enrichedin the heavy REE. The silicate phases
of pallasites and mesosiderites were shown to be sufficiently diverse
in origin such that separate classifications are entirely justified.
