Scientific paper

A petrological study of four meteorites is presented. The meteorites are a H-4 chondrite (Yamato 7301), a howardite (Yamato 7308), and two L-5 chondrites (Yamato 7304 and 7305). Meteorite pyroxenes and olivines are characterized. The howardite is a polymict breccia of diogenite and eucrite clasts, and the howardite pyroxenes form a definite trend probably related to fractional crystallization of the parental magma of the achondrite. High-temperature oligoclase is found in the chondrites while anorthite is found in the howardite. Intergrowth of nickel-iron, troilite, chromite, and rarely ilmenite is observed. Bulk composition and genetic implications are discussed.
