WitrynaMetamorphic rocks are mostly formed beneath mountain ranges where rocks are deeply buried (10 km or more) and squashed by movements of the Earth’s crust. This is called Regional Metamorphism because large regions of rock are affected. However, rocks can also be metamorphosed at shallower depths if they are heated up by nearby … Witryna16 mar 2024 · Natural shock metamorphism is the physical consequence of hypervelocity impact of a projectile (e.g., asteroids and comets) into solid target rock, sediment, and regolith exposed on planetary bodies (Stöffler et al. 2024).During passage of the shockwave generated from the impact event, the increase in internal energy … WitrynaMetamorphism is the transformation of existing rock (the protolith) to rock with a different mineral composition or texture.
