H/L4/5 Meteorite Classification

Class Description

The H/L4/5 meteorite classification refers to a type of ordinary chondrite meteorite that could belong to either the H group, known for high iron content, or the L group, with lower iron levels, and is a combination of petrologic types 4 and 5. This classification indicates that the meteorite has undergone significant metamorphic changes, including the homogenization of olivine compositions, transformation of pyroxene minerals, and the development of secondary minerals, blurring the original chondrule outlines found in these meteorites.
