Witryna22 maj 2024 · Regional Metamorphism. When rocks are buried deep in the crust, regional metamorphism occurs. This is commonly associated with the boundaries of convergent plate and mountain range formation. Because burial is required from 10 km to 20 km, the affected areas tend to be large. It happens in a much larger area. Witryna28 sie 2024 · No headers Figure 8.11: Prograde and retrograde metamorphism. Prograde metamorphism occurs when low-grade or unmetamorphosed rocks change mineralogy or texture in response to a temperature increase. If the metamorphism is gradual and predictable, we call it progressive metamorphism.During progressive … how do you sell patterns on ravelry

It is characterized by extremely high P/T conditions … Shock metamorphism or impact metamorphism describes the effects of shock-wave related deformation and heating during impact events. The formation of similar features during explosive volcanism is generally discounted due to the lack of metamorphic effects unequivocally associated with explosions and the difficulty in reaching sufficient pressures during such an event.
