Is anthracite a sedimentary or a igneous rock?
Anthracite is a metamorphic rock, not a sedimentary or igneous rock. It forms from the metamorphism of bituminous coal, under high pressure and temperature conditions deep within the Earth's crust.
If a metamorphic rock contains and intrusion of igneous rock which rock is the oldest?
In this scenario, the igneous rock intrusion is the youngest rock, as it formed after the metamorphic rock was already in existence. The metamorphic rock must have been present before the igneous rock intruded into it, making the metamorphic rock the oldest of the two. Thus, the metamorphic rock is the oldest in this context.
What can change a igneous rock into a metamorphic rock?
The process that can change an igneous rock into a metamorphic rock is called metamorphism. This occurs when the igneous rock is subjected to high temperatures and pressure deep within the Earth's crust. These conditions cause the minerals in the rock to recrystallize and realign, forming a new metamorphic rock with different physical and chemical properties.
Is cinnabar a igneous metamorphic or sedimentary rock?
igneous
What condition change igneous sedimentary to metamorphic rock?
The conditions that change igneous or sedimentary rock into metamorphic rock include high temperature, high pressure, and the presence of chemically active fluids. These conditions cause the minerals in the original rock to recrystallize, forming new minerals and textures characteristic of metamorphic rocks.
For metamorphic rock to become igneous rock what steps are necessary?
Metamorphic rock can not become igneous rock, however igneous rock can become metamorphic. This process happens over time as the rocks are shifted, compressed and heated by the Earth.
Can igneous rock be formed into a metamorphic rock?
An igneous rock can be metamorphosed (changed) into a metamorphic rock but will no longer be an igneous rock. An igneous body can be intruded into metamorphic rocks but will still be an igneous rock that is different from the surrounding metamorphic rocks. Ethier answer work depending on how the question is read.
How metamorphic rock turns into igneous?
Metamorphic rock becomes igneous rock when it is melted, then solidifies.
How can an igneous rock become a metamorphic?
A metamorphic rock can become a igneous rock by melting and cooling
What conditions are necessary to turn igneous and sedimentary rocks into metamorphic rocks?
Great pressure and heat, but short of the temperature that would completely melt the rock.
Which metamorphic rock changes to an igneous rock?
Any metamorphic rock can melt and recrystallize and become an igneous rock.
How do metamorphic rocks change into igneous rock?
The metamorphic rock melts into magma then cools into igneous rock
The melting of metamorphic or igneous rock forms what substance?
The melting of metamorphic or igneous rock forms magma.
Are metamorphic rock only made out of from igneous?
No, metamorphic can be formed by either igneous or sedimetary rock.
Can a metamorphic rock go back into and igneous rock?
Yes. A metamorphic rock can melt and the re-solidify as an igneous rock.
How metamorphic rock can change to igneous rock?
if the igneous rock is put under heat and pressure it turns into a metamorphic
Is a seashell an igneous sedimentary or metamorphic rock?
metamorphic rock
