Physical properties
Hardness: 4.5-5.5; Color: Black fusion crust with brownish-gray interior; Luster: Dull to sub-metallic; Crystal structure: Contains small spherical grains called chondrules; Cleavage: None; Specific gravity: 3.0-3.8 (notably denser than terrestrial rocks)
Formation & geological history
Formed roughly 4.6 billion years ago in the solar nebula. These are remnants from the early formation of the Solar System that have fallen to Earth from the asteroid belt. The dark surface is a fusion crust created by intense heat during atmospheric entry.
Uses & applications
Scientific research into the formation of the solar system, high-end collector market, and occasionally used in custom jewelry (slices).
Geological facts
Chondrites are the most common type of meteorite, accounting for about 86% of all falls. They contain the oldest solid materials in our solar system, sometimes pre-dating the formation of the Sun itself.
Field identification & locations
Identify in the field by checking for a dark 'fusion crust,' magnetic properties (usually attracts a magnet due to nickel-iron content), and notable weight for its size. Common search locations include deserts or ice fields where dark rocks stand out.
