IIE iron meteorite : ウィキペディア英語版 | IIE iron meteorite
The iron meteorites of the IIE chemical type are octahedrites of various coarseness, most of which contain numerous inclusions of recrystallized stony silicates. ==Composition and origin== They have mineral compositions and oxygen isotope ratios very similar to the H chondrites, which makes it probable that they originate from the same parent body. The best candidate for this parent body is the S-type asteroid 6 Hebe.〔(M. J. Gaffey & S. L. Gilbert, "Asteroid 6 Hebe: The probable parent body of the H-Type ordinary chondrites and the IIE iron meteorites" ), ''Meteoritics & Planetary Science'', Vol. 33, p. 1281 (1998).〕 Unlike most iron meteorites, the type IIE are thought to have been melted out of the chondritic surface of the parent asteroid by impacts during its early history.
