H3.8/3.9 Meteorite Classification

Class Description

The H3.8/3.9 meteorite classification describes a specific type of ordinary chondrite from the high-iron H group, exhibiting traits of petrologic types 3.8 and 3.9. These meteorites are characterized by a significant amount of chondrules, minimal water-based alterations, and mineral compositions that are not fully uniform, with their subtype numbers indicating a higher degree of thermal metamorphism, nearing the transition to type 4, but not completely achieving it.
