CO3.5 Meteorite Classification

Class Description

The “CO3.5” classification is assigned to a carbonaceous chondrite in the CO group, signifying it as a type 3 meteorite with a level of metamorphism that places it towards the higher end of this category. Characterized by a mix of small chondrules and minimal refractory inclusions, these meteorites exhibit a balance of abundant chondrules and minerals that are not yet fully equilibrated, including low-calcium pyroxene grains with distinctive twinning.
