Impactites: Impact Breccia, Tektites, Moldavites, Shattercones
Sand can melt into impact glasses such as Libyan Desert Glass and Darwin Glass; rocks may be shattered and compressed into breccias such as suevite that contain minerals formed at high pressure—the Nördlinger Ries crater in Germany provides excellent examples.
Impactite - Wikipedia
When a meteor strikes a planet's surface, the energy released from the impact can melt rock and soil into a liquid. The liquid then cools and becomes an impact melt. [2] If the liquid cools and hardens quickly into a solid, impact glass forms before the atoms have time to arrange into a …
Moldavite - Wikipedia
Moldavite (Czech: vltavín) is a forest green, olive green or blue greenish vitreous silica projectile glass formed by a meteorite impact in southern Germany (Nördlinger Ries Crater) [3] that occurred about 15 million years ago. [4] It is a type of tektite and a gemstone. [5]
Real vs Fake Moldavite: How Can You Tell the Difference?
Nov 9, 2021 · Moldavite is a type of glass that was formed by a meteorite impact. It’s known as a tektite or impact glass, and comes mainly from the Nordlinger Ries crater in central and eastern Europe. When the meteor hit the Earth’s surface, it created a debris field that combined meteorites and terrestrial rock that was flung hundreds of miles away ...
Libyan desert glass - Wikipedia
Meteoritic origins have long been considered possible, and recent research links the glass to impact features, such as zircon breakdown, vaporized quartz and meteoritic metals, and to an impact crater.
Moldavite - A green gem material formed by an asteroid impact.
Moldavite (also called Bouteille Stone or vltavin) is a natural glass that is thought to have formed in the heat of an asteroid impact. This event occurred about 15 million years ago, and a splatter of hot glass formed a strewn field across central Europe .
Collecting Guide: Impactites, impact Glass and Libyan desert glass
Impact glass is a variety of impactite which reached a very high temperature then cooled very quickly, and whose silica concentration is sufficiently high that it is more of a glass than solidified molten rock.
Are you sure Tektites are Meteorite Impact glasses?
In this image, the front row shows a selection of impact glasses found in either the immediate vicinity of an impact crater or thought to be proximal. The back row includes examples of all of the five generally accepted tektite strewn fields known.
Iron projectile fractionation processes in siliceous glass from small ...
Jun 1, 2024 · The results provide new insights on target-projectile interactions, and highlight the influence of immiscible metal spherule formation on the composition of ejected glass from small impact structures formed by iron meteorites.
