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 [edit]
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.[1] 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.
Rarity [edit]
It is a rare type with 21 known members as of 2009.[2]
