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 · A positive correlation between diamond content and the amount of phosphorus pentoxide in impactites indicates links to C and P probably in organic matter of the primary sedimentary rocks, which were subjected to granulitic metamorphism 2.4 Ga ago and melted at the time of impact 35.7 Ma ago. incentive value definition psychology
