内容記述 | Yamato-694 meteorite collected near the Yamato Mountains in Antarctica in 1969 is an ordinary chondrite belonging to a high-iron group. Major chemical composition of its silicate minerals was determined by electron probe microanalysis. Molar composition of olivine, orthopyroxene and plagioclase is (Fo)_<81>, (En)_<82> and (An)_<10>, respectively. In comparison with the analytical data of silicate minerals in ordinary chondrites, the chemical composition of olivine, orthopyroxene and plagioclase in Yamato-694 meteorite agrees with that of silicate grains in equilibrated high-iron chondrites. The result corresponds to the microscopic feature of this meteorite specimen showing an advanced recrystallization texture. | |||||||||
