Physical properties
Hardness: 3-5 Mohs. Color: Dark gray to black matrix with white/tan inclusions. Luster: Dull to sub-metallic. Contains Chondrules (round grains) and CAIs (white Calcium-Aluminum-rich inclusions). Presence of organic compounds and water-bearing minerals.
Formation & geological history
Formed in the early solar nebula approximately 4.56 billion years ago. These are some of the most primitive materials in the solar system, originating from undifferentiated asteroids that have remained largely unchanged since their formation.
Uses & applications
Scientific research into the origins of the solar system and life, high-end collector market, and educational museum displays.
Geological facts
The CV3 group is famously represented by the Allende meteorite, which fell in Mexico in 1969. It contains pre-solar grains that are older than the Sun itself.
Field identification & locations
Identify by a dark, charcoal-like appearance, a thin fusion crust if fresh, and the presence of small spherical chondrules when sliced. Usually found using metal detectors or visual surveys in arid desert regions like the Sahara or Antarctica.
