Granite is turned into the metamorphic rock gneiss by heat and pressure that is normally regional in nature, i.e., it will cover a broad expanse of geography due to the actions of tectonic plate movements, and in particular, plate collisions. The incredible pressures that are experienced in a granite that is being subjected to these forces will cause the minerals in the rock to align themselves perpendicularly to the direction of the force being applied, causing a narrow parallel banding in their appearance called foliation.

∙ 12y agoA metamorphic rock becomes granite by hitting a magma chamber in the ground and melting (becoming molten rock) And it depends on if the volcano is intrusive or extrusive,and how fast the melted rock cools and hardens. Granite is intrusive so it cools slowly, creating large crystals.

Granite gneiss is a metamorphic rock formed from granite.
Gneiss, Schist, Quartzite.

What type of rocks are banded or non banded?
Slate is a type of metamorphic rock. It is a foliated metamorphic rock that has a banded, or layered, appearance due to exposure to directed pressure and heat.
Can metamorphic rocks from from other metamorphic rocks?
Yes. Most likely it would become a metamorphic rock of higher grade. Slate is a low grade metamorphic rock. With increased heat and pressure it will become schist, a high grade metamorphic rock.
What are the parent rocks of the metamorphic rock?
1. Marble ----- Limestone or dolostone 2. Gneiss ----- Granite or schist 3. Quartzite --- Sandstone 4. Schist ----- phyllite
How metmorphic rock form?
Metamorphic rocks are rocks which have changed from one form to another due to intense heat or pressure. Any rock (sedimentary, metamorphic, and igneous) can be changed into a metamorphic rock.
Is glassy igneous rocks intrusive or extrusive?
Granite gneiss is a metamorphic rock and would not be considered extrusive (rock formed from molten material at or near the surface).
How do you change granite from sedimentary rocks to metamorphic rocks?
Gneiss is a foilated metamorphic rock.
A metamorphic rock formed form granite?
Gneiss
What rock does granite form from heat and pressure?
The ONLY rock that Granite forms is the metamorphic rock Gneiss. Granite is the parent rock of Gneiss.
What was gneiss before it undertook heat and pressure?
A mixture of sand and clay, mudstone, metamorphose (process of changing from one type of rock into a metamorphic rock) into gneiss rocks or schist rocks. The mudstones would change under heat and pressure to make the new Metamorphic rocks.
What rocks form from existing rocks?
metamorphic rock
What type of rocks are banded or non banded?
Slate is a type of metamorphic rock. It is a foliated metamorphic rock that has a banded, or layered, appearance due to exposure to directed pressure and heat.
What rock can only be formed from sedimenta rock or igneous rock?
Metamorphic rocks. With proper heat and pressure sedimentary and igneous rocks can form metamorphic rocks.
Is gneiss metamorphic?
A gneiss is a metamorphic rock. Metamorphic rocks are created by the alteration of rocks by heat and pressure. Therefore, a gneiss may be created from an igneous rock in which case it would be called an orthogneiss.
Can metamorphic rocks from from other metamorphic rocks?
Yes. Most likely it would become a metamorphic rock of higher grade. Slate is a low grade metamorphic rock. With increased heat and pressure it will become schist, a high grade metamorphic rock.
What are the parent rocks of the metamorphic rock?
1. Marble ----- Limestone or dolostone 2. Gneiss ----- Granite or schist 3. Quartzite --- Sandstone 4. Schist ----- phyllite
What igneous rock forms from granite?
Granite is already an igneous rock. If the granite simply melts and re-solidifies it will become granite again. If it melts and is erupted from a volcano, it will form rhyolite. If it melts and mixes with magma of a different composition, then it could form any number of igneous rocks.
What rocks can granite turn in to?
Granites can turn into metamorphic, sedimentary, or igneous rock through metamorphosis.
