CO3.1 Meteorite Classification

Class Description

The classification “CO3.1” refers to a specific type of carbonaceous chondrite meteorite from the CO group, characterized by its close-to-solar magnesium and silicon ratios and oxygen isotopes that differ from those on Earth. These meteorites, specifically of the Ornans (CO) chemical group, contain small chondrules and inclusions, occupying about half of their volume, and show minimal signs of water-based alteration. They are also marked by a notable presence of chondrules, minimal water alteration, and a mixture of different minerals that haven’t fully chemically combined.
