A vesicular, glassy to finely crystalline material produced by fusion or partial fusion of target rock by the heat generated from the impact of a large meteorite, and occurring in and around the resulting crater, typically as individual bodies composed of mixtures of melt and rock fragments, often with traces of meteoritic material; a rock ...
Impactites
Did you know?
Witryna"Impactites" refer generally to materials that have been produced by meteorite impacts, including melted rocks, shocked minerals, shatter cones, and flaegle. Samples of rock containing spherule layers from giant impacts like Chicxulub (66 million years ago) and Chesapeake Bay (35.5 Ma) are also in the collection.

WitrynaIt is suggested that feldspathic granulitic impactites, which are characterized by a high model plagioclase content of between 70 and 80%, all formed in the period after consolidation of the lunar crust and before the final bombardment. The granulitic impactites contain essentially no KREEP component, which suggests that KREEP … WitrynaCe microscope pour étudiants permet grâce son écran LCD de 88,8 mm à plusieurs personnes à la fois d'observer des objets.

Rochechouart (population about 3800) is built with rocks created or modified by the impact (impactites).
WitrynaImpactites represent unique lithologies formed as the result of hypervelocity impact events on terrestrial planetary bodies (Stöffler and Grieve, 2007).The nature and emplacement of impactites are unequivocally related to the shock dynamics (e.g., size of the impactor), type of environment (oceanic vs. continental), and the target …
Witryna15 wrz 2024 · The lack of vegetation and extensive soils in this environment means that the physical and chemical characteristics of the impactites dominate the behavior and distribution of surface microbial communities (Cockell et al.,2005).

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.
