It is altered physically by pressure and heat and can align the existing minerals into layers or bands called foliations; new minerals may be formed from the minerals that existed before the metamorphism; aqueous solutions between rock particles are squeezed out; and existing minerals may recrystallize.
What else can I help you with?
What is the original rock called before metamorphism takes place?
It is called the 'protolith' or 'parent rock'.
When changes in pressure temperature or chimical make-up alter a rock what takes place?
metamorphic rock metamorphic rock, or metamorphism
What takes place when changes in presure or temperature or chemicle makeup alter a rock?
Metamorphism. Also, learn how to spell properly.
What has to happen for metamorphism?
the parent rock must be in solid form
What happen for metamorphism to occur?
the parent rock must be in solid form
What is a nonfoliated rock formed by contact metamorphism of a shale or mudstone?
A nonfoliated rock formed by contact metamorphism of a shale or mudstone is called hornfels. It usually has a fine-grained texture and lacks the layering characteristic of foliated rocks. Hornfels forms when the parent rock is subjected to high temperatures and pressures near a magma intrusion.
Where does metamorphism take place And?
Metamorphism takes place primarily in the Earth's crust, where rocks are subjected to high temperatures and pressures, typically at depths of several kilometers. This process often occurs at tectonic plate boundaries, particularly in regions of subduction and continental collision. Additionally, metamorphism can occur in areas with intrusions of magma, where heat from the molten rock alters surrounding rocks.
How can one type of rock become another type of rock how is it possible?
One type of rock can transform into another type of rock through the process of metamorphism, which occurs due to changes in temperature, pressure, or the presence of fluids. During metamorphism, the mineral composition and texture of the rock can change, resulting in the formation of a new type of rock. This process usually takes place deep within the Earth's crust over long periods of time.
The kind of metamorphism that occurs when rock come into contact with a heat source such as magma and the rock surrounding the heat source get cooked?
It is called contact metamorphism. It takes place when the magma at high temperature tries to break out from the magma chamber, it then comes into contact with the country rock at high pressure and temperature.
How could an igneous rock change to a metamorphic rock?
Under influence of pressure and temperature, a rock can change, the process is called deformation or metamorphism, the result is a metamorphic rock. This can happen to igneous rocks as well.
What is the difference between regional and contact metamorphism?
Regional metamorphism is the creation of metamorphic rock from large geographically significant processes like plate tectonics. Contact metamorphism is the creation of metamorphic rock from the proximity of an existing rock to a heat source provided by a plutonic intrusion.
What is the difference between contact and metamorphism?
Contact metamorphism is metamorphism that happens when preexisting rock comes in contact with a molten rock or magma and it melts locally.Regional metamorphism is metamorphism happens when two plates collide the plate that subducts can melt by the heated area.
