Tektite is a geological term used to describe natural glass formed from meteorite impacts. The word is pronounced /ˈtektət/ and spelled with a "k" instead of a "c" to reflect its Greek roots. The "tekt-" prefix comes from the Greek word "tektos," meaning "melted," while the suffix "-ite" indicates a mineral or rock. Due to their extraterrestrial origin and unique properties, tektites are highly sought after by collectors and scientists interested in the study of meteorites and impact craters.
A tektite refers to a small, glassy object that has been formed as a result of a high-velocity impact between a meteorite and the Earth's surface. It is primarily composed of natural glass, typically with a silicate composition, but can also contain small amounts of impurities such as iron or other elements. Tektites are often black, green, or brown in color and exhibit a distinctive shape characterized by a smooth or pitted surface, typically resembling that of a droplet or a button.
These unique objects are created when a meteorite or asteroid collides with the Earth's surface, generating immense heat and pressure. As a result, the rocks and minerals near the impact site become molten and are ejected into the atmosphere. While still in a molten state, the material cools and solidifies, rapidly forming tektites over a relatively short time frame.
Tektites are typically found in strewn fields or concentrated areas, often associated with ancient impact craters. Their distribution can span vast regions, crossing continents or even oceans. These geological remnants provide valuable information to scientists in the study of impact events, as they can help determine the approximate age, location, and nature of past meteorite impacts on Earth.
Due to their unique origins and distinct characteristics, tektites are widely sought after by collectors and enthusiasts, as they hold a significant scientific and aesthetic value.
The word "tektite" has its roots in the Greek language. It is derived from the Greek words "tektos", meaning "molten", and "lithos", meaning "stone". The term was first used by Austrian mineralogist Franz Eduard Suess in 1900 to describe a specific type of natural glass formed during meteorite impacts on Earth. Tektites are typically black, green, or brown in color and have distinctive shapes that resemble droplets or aerodynamic forms.
