The Fascinating World of Tektites: A Look at Different Types
Tektites are enigmatic natural glasses formed from terrestrial debris ejected during meteorite impacts. These intriguing objects come in various types, each with its own unique characteristics and origins. Let’s explore some of the different tektite types found around the world:
Australites
Australites are tektites found in Australia and Southeast Asia. They are typically dark in colour, ranging from black to brown, and exhibit a characteristic button or dumbbell shape. Australites are believed to have formed from the impact of a meteorite around 0.8 million years ago.
Indochinites
Indochinites are tektites primarily found in Vietnam, Laos, and China. They are known for their dark green or black colour and irregular shapes. Indochinites are thought to have originated from a large impact event that occurred around 800,000 years ago.
Moldavites
Moldavites are green tektites found in the Czech Republic and surrounding areas. They have a distinct olive-green hue and often exhibit intricate surface features known as “sculpted” textures. Moldavites are believed to have formed from the impact of a meteorite over 14 million years ago.
Bediasites
Bediasites are tektites discovered in Texas, USA. They are characterised by their dark brown to black colouration and irregular shapes resembling droplets or buttons. Bediasites are estimated to have formed from an impact event around 35 million years ago.
Each type of tektite provides valuable insights into past meteorite impacts and the processes involved in their formation. Studying these enigmatic glassy objects not only sheds light on Earth’s geological history but also offers clues about extraterrestrial events that have shaped our planet over millions of years.

Tektites are natural glass objects formed from terrestrial debris ejected during meteorite impacts.
Tektites are intriguing natural glass objects that originate from terrestrial debris expelled during meteorite impacts. These enigmatic formations, often found in various parts of the world, offer a unique glimpse into the violent processes that occur during cosmic collisions. Through their composition and characteristics, tektites provide valuable clues about the intense heat and pressure involved in their creation, serving as tangible reminders of the dynamic relationship between Earth and celestial bodies.
The four main types of tektites are splash-form, aerodynamically shaped, Muong Nong-type, and layered.
Tektites, fascinating natural glasses formed from terrestrial debris during meteorite impacts, come in four main types: splash-form, aerodynamically shaped, Muong Nong-type, and layered. Splash-form tektites are irregularly shaped with features resembling splashes of liquid frozen in time. Aerodynamically shaped tektites exhibit streamlined forms due to their high-speed ejection from impact sites. Muong Nong-type tektites are unique to Southeast Asia and showcase distinctive characteristics. Layered tektites have intricate internal structures that provide valuable insights into their formation processes. Each type offers a glimpse into the diverse nature of tektites and the intriguing mechanisms behind their creation.
Tektites are usually black or dark brown in colour due to their high iron content.
Tektites are commonly characterised by their dark hues of black or deep brown, a result of their elevated iron content. This distinctive feature sets tektites apart from other types of natural glasses and minerals, giving them a unique appearance that reflects their extraterrestrial origins. The presence of high levels of iron contributes to the intense colouration observed in these enigmatic glassy objects, offering a visual clue to their composition and formation processes.
Splash-form tektites have irregular shapes with characteristic surface features like wrinkles and bubbles.
Splash-form tektites are a fascinating type known for their irregular shapes and distinctive surface features such as wrinkles and bubbles. These unique characteristics are a result of the rapid cooling and solidification process that occurs when molten material is ejected during meteorite impacts. The presence of these intricate textures adds to the allure of splash-form tektites, providing valuable clues about the intense forces at play during their formation.
Aerodynamically shaped tektites have streamlined forms due to their flight through the atmosphere during ejection.
Tektites that exhibit aerodynamically shaped forms have streamlined designs as a result of their journey through the Earth’s atmosphere during ejection. The unique shapes of these tektites, such as buttons or dumbbells, are a direct consequence of the forces and conditions experienced during their high-speed flight. This aerodynamic shaping provides valuable clues about the trajectory and velocity of these mysterious glassy objects as they were propelled from impact sites, offering a fascinating glimpse into the dynamic processes involved in their formation and distribution across different regions.
Muong Nong-type tektites are typically larger and exhibit a more irregular shape compared to other types.
Muong Nong-type tektites stand out for their larger size and distinctive irregular shapes when compared to other tektite types. These fascinating glassy objects offer a unique glimpse into the impact processes that give rise to tektites, showcasing the diversity and variability in their formation. Studying Muong Nong-type tektites provides valuable insights into the dynamics of meteorite impacts and the intriguing characteristics of these enigmatic natural glasses.
Layered tektites have distinct layers caused by the melting and solidification process during impact events.
Layered tektites exhibit unique characteristics due to the melting and solidification process that occurs during impact events. These distinct layers, formed as a result of intense heat and pressure, provide valuable insights into the dynamic processes involved in the creation of these enigmatic glassy objects. By studying layered tektites, scientists can unravel the intricate details of meteorite impacts and gain a deeper understanding of the geological phenomena that shape our planet’s history.
Tektites are found in various parts of the world, with notable strewn fields in Southeast Asia, Australia, and Central Europe.
Tektites, intriguing natural glasses formed from terrestrial debris during meteorite impacts, are discovered in diverse regions worldwide. Notable strewn fields of tektites can be found in Southeast Asia, Australia, and Central Europe. These areas have yielded a rich variety of tektite types, each offering valuable insights into the geological history and impact events that have shaped these regions. The presence of tektites in these distinct locations highlights the global reach of meteorite impacts and the fascinating dispersion patterns of these enigmatic objects across different continents.
