During metamorphism of granite into gneiss what happens to the minerals?
Wiki User
∙ 15y ago
With the extreme heat and pressure causing the metamorphism into gneiss, the constituent minerals recrystallize into bands, usually alternating from light colored to dark, perpendicular to the direction of the pressure which is being applied. The exact cause of the banding is not fully understood at this time.

What two properties of rock change during metamorphism?
The properties of temperature and pressure both change when rocks undergo metamorphism. Re-crystallization and chemical reactions also occur during metamorphism.
What process can occur during metamorphism?
everything
What physical change in metamorphic rock signals the end of metamorphism?
from what i know there is no physical change that signals the end of metamorphism but there is a physical change during the process of metamorphism. during metamorphism the shape of the rock changes due to force of stress this is a physical change. (a physical change is when the shape or composition ofa substance e.g. rock has changed). by the way i am only 12
What happens to minerals during metamorphism?
Metamorphic rocks are created from rocks that are deformed by tectonic forces and/or are brought to temperature that are much different from those that they were first formed in (usually hotter). The effect of increased temperature is the growth of minerals from others that are no longer stable under the changed pressure and temperature conditions (e.g. diamond is formed from graphite under very high pressure and garnet growths at high temperatures and pressures from aluminium rich usually sedimentary rocks). The effect of shear stress on the rock (i.e. directed force creating not only compression but also deformation) is the change of shape of minerals as well as rotation and alignment of platy minerals into bands. These processes lead to the usually banded appearance of metamorphic rocks.
When hot fluids migrate into and out of a rock during metamorphism what will change?
grade

Do minerals partly melt during metamorphism?
no
Why does the color of sedimentary rock change during metamorphism?
The color of sedimentary rock changes during metamorphism due to minerals. New minerals introduced can change the color of the rock.
What is the planar alignment of minerals due to differential stress during metamorphism?
Foliation
Why does the color of granite never change?
The colour of granite does in fact change. For example it will change during the weathering process where feldspar minerals will change to clay minerals such as kaolinite. If the degree of weathering is high this can significantly alter the colour of the granite.
What is recrystallization process?
A process by which bonds between atoms in minerals break and reform in new ways during metamorphism.
Where does the water involved in melting at subduction zones come from?
Water contained within minerals in the subducting plate is released during metamorphism.
Metamorphism occurs at hotspots where magma rises up through Earth.?
