Physical properties
Hardness: 5-6 (Mohs); Color: Dark brown to black fusion crust, grayish-speckled interior; Luster: Sub-metallic to dull; Crystal structure: Amorphous/Granular with Chondrules; Cleavage: None; Specific gravity: 3.0-3.8.
Formation & geological history
Formed through the accretion of dust and grit in the early solar nebula approximately 4.5 billion years ago. These are remnants of asteroids that never underwent planetary differentiation.
Uses & applications
Primarily for scientific research into the early solar system and for private mineral/meteorite collections. Larger pieces are sometimes used for high-end jewelry (inlays).
Geological facts
Chondrites contain 'chondrules'—small, round droplets of once-molten silicate minerals that are among the oldest materials in our solar system. Over 85% of meteorites that fall to Earth are chondrites.
Field identification & locations
Identify in the field by checking for a faint attraction to magnets (due to iron-nickel content), a high density for its size, and the presence of a thin, weathered 'fusion crust'. Found globally, but most easily spotted in deserts or ice fields.
