EH4 Meteorite Classification

Class Description

The “EH4” classification denotes an enstatite chondrite from the high-iron EH group, known for small chondrules and a unique, highly reduced mineral composition with elements like niningerite and perryite. This type 4 meteorite has experienced significant metamorphism, leading to uniform olivine compositions, recrystallization of its matrix, and the absence of primary igneous chondrule glass.
