 note = {P(論文), Unusual inclusions occur within olivine megacrysts in the DaG735 olivine-phyric shergottite. They consist of pyroxene and chromite in a ratio of about 2:1, and show strange textures. They are grouped into two types, symplectic and non-symplectic. The pyroxenes in unusual inclusions are similar in composition to those in the main lithology of DaG735, but the chromites differ in TiO_2 contents which are lower by half than those of chromites in the main lithology. The symplectic textures indicate exsolution origin of the unusual inclusions within olivine megacrysts, and the reaction to produce the unusual inclusions suggests that the original olivine megacrysts may have contained some amounts of Cr^(+2) in addition to Cr^(+3), and the Cr^(+2) was oxidized to Cr^(+3) during the formation of the unusual inclusions.},
