Physical properties
Hardness: 5-6 (variable), Color: Dark brown to black (fusion crust) with gray interior, Luster: Metallic to dull, Structure: Contains small spherical chondrules, Cleavage: None, Specific Gravity: 3.0-3.8
Formation & geological history
Formed through the accretion of dust and grains in the early Solar System approximately 4.5 billion years ago. These are fragments of asteroids that have not undergone melting or differentiation.
Uses & applications
Primary value is for scientific research into the early solar system and for private mineral/meteorite collectors.
Geological facts
Chondrites are the most common type of meteorite that reaches Earth, accounting for about 86% of all falls. They contain elements in roughly the same proportions as they are found in the Sun, minus volatile gases.
Field identification & locations
Identify by looking for a flight-worn fusion crust, attraction to a strong magnet due to iron-nickel content, and 'thumbprints' (regmaglypts). When cut, tiny circles called chondrules should be visible. They are most easily found in arid deserts or Antarctic ice fields.
