Inclusions within olivine in an Esquel pallasite of the Main group pallasite was investigated using electron microprobe analysis and Raman spectroscopy. Esquel pallasite consists mainly of olivine, Ni-Fe metal, and aggregates of fine minerals. The average Fo content of olivine is 88.3. The inclusions within olivine crystals occur as droplets, grains of irregular form and tubular form.
