Physical properties

Hardness: 5.5-6.5 on Mohs scale. Color: Black to dark brown. Luster: Vitreous to dull. Crystal structure: Amorphous (glass). Cleavage: None, exhibits conchoidal fracture. Specific gravity: 2.3-2.5.

Formation & geological history

Formed by the impact of large meteorites on the Earth's surface, which melts the surrounding terrestrial rock and ejects it into the atmosphere where it cools rapidly to form glass before falling back to Earth.

Uses & applications

Mainly collected by meteorite and mineral enthusiasts. Sometimes cut or tumbled for use in jewelry.

Geological facts

Tektites are named after the Greek word 'tektos', meaning molten. The most common type is the Indochinite, found in Southeast Asia and Australia. They often have aerodynamic shapes like spheres, teardrops, or dumbbells, formed during their flight through the atmosphere.

Field identification & locations

Identify by its glassy texture, lack of crystals, conchoidal fracture, and often pitted or aerodynamic surface. Common in specific strewn fields globally.
