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.

During metamorphism of granite gneiss what happens to minerals?

The exact cause of the banding is not fully understood at this time.
What type of rock would result from the metamorphism of granite?
The metamorphism of granite would likely result in the formation of gneiss, a coarse-grained foliated rock with distinct bands of minerals. The high temperature and pressure during metamorphism would cause the minerals in the granite to recrystallize and align, giving gneiss its characteristic banded appearance.
When metamorphism of granite into gneiss what happens to the minerals?
During the metamorphism of granite into gneiss, the minerals undergo recrystallization due to increased temperature and pressure. This process causes the original minerals, such as quartz and feldspar, to align and form distinct bands or foliation in the rock. The mineral composition may also change as new metamorphic minerals, like biotite or garnet, develop in response to the altered conditions. Overall, the texture and structure of the rock are transformed, resulting in a more foliated appearance characteristic of gneiss.
What happens to granite if you put it under heat and pressure?
When granite is subjected to heat and pressure, it undergoes a process called metamorphism and can transform into a metamorphic rock called gneiss. The mineral composition and texture of the granite change during this process, resulting in a foliated texture and alignment of minerals in the gneiss.
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.
When gneiss is formed... quartz... feldspar... mica... and other minerals of granite are rearranged into alternation WHAT?
When gneiss is formed, quartz, feldspar, mica, and other minerals of granite are rearranged into alternating light and dark bands or sheets. This distinctive layering is a result of the intense heat and pressure that gneiss is subjected to during the process of metamorphism.
If granite was subjected to intense heat and pressure it would most likely change to?
If granite is subjected to intense heat and pressure, it would most likely change into a metamorphic rock called gneiss. This transformation occurs through a process known as metamorphism, where the minerals within the granite recrystallize and realign under the new conditions, often resulting in a banded appearance. The specific characteristics of the resulting gneiss can depend on the original composition of the granite and the environmental conditions during metamorphism.
What is an agent of metamorphism related to temperature?
An agent of metamorphism related to temperature is heat. Heat causes minerals in rocks to recrystallize or change mineral composition, leading to metamorphic changes in the rock. Temperature influences the degree of metamorphism and the types of minerals that form during the process.
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 type of metamorphic rock is similar to granite?
A type of metamorphic rock similar to granite is gneiss. Gneiss is a foliated metamorphic rock that has a similar composition to granite but displays a banded texture due to the alignment of mineral grains during metamorphism.
