Physical properties
Hardness: 5-6 (Mohs); Color: Dark gray to black fusion crust, light gray/tan interior with tan pyroxene and white feldspar; Luster: Sub-vitreous to dull; Crystal structure: Phaneritic (coarse-grained); Specific gravity: 2.8-3.2
Formation & geological history
Igneous rock formed from the crust of the asteroid 4 Vesta approximately 4.5 billion years ago. These are basaltic rocks that cooled from magma on a differentiated celestial body.
Uses & applications
Scientific research into planetary formation; highly sought after by private collectors and museums.
Geological facts
Eucrites belong to the HED (Howardite-Eucrite-Diogenite) group of meteorites, which astronomers have linked to asteroid 4 Vesta through spectroscopy.
Field identification & locations
Identify by looking for a black fusion crust, lack of significant metallic iron (low magnetism compared to chondrites), and a crystalline basaltic texture. Common in hot deserts like the Sahara where they are easier to spot.
