Impactites
Did you know?
Impactite is rock created or modified by one or more impacts of a meteorite. Impactites are considered metamorphic rock, because their source materials were modified by the heat and pressure of the impact. On Earth, impactites consist primarily of modified terrestrial material, sometimes with … Zobacz więcej When a large meteorite hits a planet, it can radically deform the rocks and regolith that it hits. The heat, pressure, and shock of the impact changes these materials into impactite. Only very massive impacts generate the … Zobacz więcej Impactite has been found, for example, at the following impact craters and structures: • Alamo bolide impact (Late Devonian), Nevada, United States • Alga crater on the planet Mars Zobacz więcej Impactite includes shock-metamorphosed target rocks, melts (suevites) and mixtures of the two, as well as sedimentary rocks with significant … Zobacz więcej • Glossary of meteoritics • Meteorite shock stage • Vitrified sand Zobacz więcej • Meteorite crater glossary Zobacz więcej Witryna4 lut 2010 · Abstract— An important and poorly understood group of rocks found in the ancient lunar highlands is called “feldspathic granulitic impactites.” Rocks of the granulite suite occur at most of the Apollo highlands sites as hand samples, rake samples, clasts in breccias, and soil fragments.

WitrynaThe meteorite collection goes back to the earliest history of the Museum. The first meteorite in the collection was a 46g piece of the Searsmont (H5 ordinary chondrite) donated in 1872 by Mr. G.M. Brainerd of Rockville, Maine. In 1874 the Museum purchased the S.C.H. Bailey mineral collection which included eight meteorites. WitrynaEcrivez-nous ; Livraison gratuite sur commandes de 75 $ et plus; S'inscrire ou S'identifier ou S'identifier
Witryna5 kwi 2024 · Impactites are formed when an asteroid or comet strikes the surface of the Earth and the impact forms a crater. The rocks of the area are blasted from the site and fall as debris. Some of the rock will be melted to one extent or another. Some melted to solid high quality glass some poorer fused into lump called Impactites and some of …
