Does metamorphism have crystals in parallel lines?

Yes, metamorphic rocks can exhibit crystals aligned in parallel lines due to the preferred orientation of minerals during deformation. This alignment is known as foliation and is commonly seen in rocks like schist and gneiss.


What is the most important agent(s) of metamorphism?

The most important agents of metamorphism are heat, pressure, and chemically active fluids. Heat causes minerals to recrystallize, pressure reorients mineral grains, and chemically active fluids introduce new elements to form new minerals. Together, these agents drive the changes in rock composition and texture during metamorphism.


What two properties of rock change during metamorphism?

During metamorphism, the texture and mineralogy of a rock can change. Texture refers to the size, shape, and arrangement of grains within the rock, while mineralogy refers to the types of minerals present in the rock.


What is metamorphic foliation?

Metamorphic foliation is a preferred orientation of mineral grains within a metamorphic rock caused by pressure during metamorphism. This alignment creates a parallel arrangement of minerals, giving the rock a layered or banded appearance. Foliation helps geologists understand the history and deformation conditions of rocks during metamorphism.


What conditions are required to form parallel alignment of minerals sometimes found in a metamorphic rock?

Parallel alignment of minerals in metamorphic rocks typically forms under high temperature and pressure conditions. This alignment occurs when minerals recrystallize and orient themselves in a preferred direction due to the stress applied during metamorphism. This process is known as foliation and results in the development of distinct parallel layers or bands of minerals within the rock.

Can a rock that is changed by metamorphism have crystals in parallel layers?

Yes, rocks that undergo metamorphism, especially foliated metamorphic rocks like schist and gneiss, can exhibit crystals arranged in parallel layers. This alignment is often a result of the directed pressure and temperature conditions during metamorphic processes, causing minerals to grow perpendicular to the direction of pressure, resulting in distinct layering or foliation.


What is a process during which there are changes in pressure temperature and chemical make up?

Metamorphism


Do Rocks formed during metamorphism depend on Earths Magnetic Field?

No, the rocks formed during metamorphism do not depend on Earth's magnetic field. Metamorphism is the process where existing rocks are altered by high pressure and temperature without being melted. The formation of metamorphic rocks is primarily influenced by the chemical composition of the original rock and the conditions present during metamorphism, such as pressure and temperature.

Do crystals grow larger during metamorphism?

During metamorphism, crystals can grow larger through a process called recrystallization, where existing minerals rearrange their atoms to form larger crystals. This can happen due to changes in temperature, pressure, or the presence of fluids in the rock. So, yes, crystals can grow larger during metamorphism.

During metamorphism of granite gneiss what happens to minerals?

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.
