Physical properties
Hardness: 5.5-6.5 on the Mohs scale. Color: typically black, dark brown, or green. Luster: vitreous (glassy). Crystal structure: amorphous (glass). Cleavage: none. Specific gravity: 2.3-2.5.
Formation & geological history
Formed by the impact of a large meteorite with the Earth's surface, which melts the surrounding rock and ejects the molten material into the atmosphere, where it cools rapidly into glass before falling back to the ground.
Uses & applications
Mainly collected by meteorite and mineral enthusiasts. Sometimes used in jewelry (like moldavite).
Geological facts
Tektites are often found in 'strewn fields' which are specific geographical areas where the impact debris landed. Famous examples include Moldavites (Europe) and Indochinites (Southeast Asia).
Field identification & locations
Identify by its glassy texture, lack of crystal structure, often pitted or aerodynamic surface shapes, and dark color. Common near known impact craters or strewn fields.
