EL4/5 Meteorite Classification

Class Description

The EL4/5 meteorite classification pertains to a specific group of meteorites known as enstatite chondrites from the EL (low-iron) subgroup, which are distinct for their sub-solar magnesium-to-silicon ratio and unique oxygen isotope compositions. These meteorites exhibit characteristics of both petrologic types 4 and 5, indicating they have experienced a degree of metamorphism that led to uniform mineral compositions and recrystallization of their matrix, but are not exclusively classified as either type, blending features from both stages.
