Physical properties
Hardness: 4.5-5.5 (Mohs), Color: Black or dark brown fusion crust with gray interior, Luster: Dull to sub-metallic, Structure: Granular with visible chondrules, Density: 3.0-3.8 g/cm3.
Formation & geological history
Formed from the solar nebula over 4.5 billion years ago. These are primitive rocks that never underwent melting or differentiation in their parent asteroid body.
Uses & applications
Extremely valuable for scientific research into the early solar system and highly prized among private collectors and museums.
Geological facts
Chondrites are the oldest known rocks in the solar system. The fusion crust seen on the surface is a thin layer of melted rock formed by friction during atmospheric entry.
Field identification & locations
Check for a dark fusion crust, presence of small spherical silicate grains (chondrules), and attraction to a magnet due to nickel-iron content. Common in desert regions or Antarctica.
