Formation & geological history
Formed from the solar nebula approximately 4.5 billion years ago. These are remnants of planetesimals that never underwent planetary differentiation, traveling through space before entering Earth's atmosphere.
Uses & applications
Predominantly used for scientific research, private collections, and occasionally sliced and polished for jewelry or high-end watch dials.
Geological facts
Chondrites contain 'chondrules'—tiny, round silicate beads that were molten droplets in space before the planets formed. They are older than any rock found on Earth.
Field identification & locations
Identify by looking for a 'fusion crust' (burnt exterior), high density, and attraction to a magnet. Commonly found in deserts or Antarctica where they stand out against the substrate. A 'window' or 'slap' can be cut to reveal the metallic flecks inside.
