Contact metamorphism.
What else can I help you with?
Which kind of metamorphism occurs next to an intrusion of molten magma?
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.
What is it called when metamorphism occurs due to heat generated by magma?
When metamorphism occurs due to heat generated by magma, it is called "contact metamorphism." This process typically happens when surrounding rocks are heated by the proximity of molten magma, leading to changes in mineral composition and texture. The effects are usually localized around the intrusion of magma, resulting in the formation of metamorphic rocks such as hornfels.
Which would you expect to cause the greatest amount of contact metamorphism an intrusion of basaltic magma or an intrusion of rhyolitic magma?
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.
What rock forming process occures when hot magma forces its way into rock?
contact metamorphism
Metamorphism that occurs because of close proximity to a mass of magma is called?
Contact metamorphism is what occurs because of close proximity to a mass of magma.
If metamorphism occurs due to heat generated by magma it is called metamorphism?
It is called contact metamorphism.
Compare and contrast contact metamorphism and regional 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.
If metamorphism occurs due to heat generated by magma it is called what?
It is called contact metamorphism.
Difference between regional and local metamorphism?
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.
What does magma intrusion means?
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.
What results when rocks come in contact with molten rocks such as those in an igneous intrustion?
When rocks come in contact with molten rocks from an igneous intrusion, the surrounding rocks may undergo contact metamorphism, where their mineralogy and texture are altered due to the heat and chemical reactions with the intruding magma. This can result in the formation of new minerals and textures in the rocks near the intrusion boundary.
What two geological processes are involved in changing sedimentary rock to a metamorphic rock?
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.
