Contact metamorphism.
Contact metamorphism occurs next to an intrusion of molten magma. This type of metamorphism happens when hot magma comes into contact with existing rock, causing the rock to undergo changes in mineralogy and texture due to the heat and pressure.
An intrusion of basaltic magma would likely cause greater contact metamorphism compared to an intrusion of rhyolitic magma. Basaltic magma has higher temperatures and higher fluidity, allowing it to heat surrounding rocks more effectively and induce more intense metamorphic changes.
contact metamorphism
Contact metamorphism is what occurs because of close proximity to a mass of magma.
It is called contact metamorphism.
It is called contact metamorphism.
Contact metamorphism is the process of forming rocks from the heat of magma intrusion. Regional metamorphism, meanwhile, is the process of forming rocks by pressure and heat at plate boundaries.
Regional metamorphism occurs over a large area and at high pressures and temperatures, typically associated with tectonic processes like mountain building. Local metamorphism, on the other hand, is confined to a small area and occurs at lower pressures and temperatures, often as a result of contact with a heat source like a magma intrusion.
Magma intrusion refers to when molten rock (magma) forces its way into existing rock formations beneath the Earth's surface. This intrusion can create new igneous rock formations, as well as potentially lead to volcanic activity if the magma reaches the surface.
contact metamorphism, regional metamorphism, dynamic metamorphism
The two processes resulting from sedimentary into metamorphic rock are known as contact metamorphism and regional metamorphism. Regional metamorphism most notably involves two tectonic plates colliding, while contact metamorphism occurs due to the intrusion of magma.
