What rocks are formed by the effect of heat and pressure on other rocks?
the metamorphic rocks are formed by heat and extreme pressure from other rocks
What are two examples of Metomorphic rocks?
Slate and marble are examples of metamorphic rocks. Other metamorphic rocks include gneiss, schist, and quartzite. All metamorphic rocks are formed from other rock types.
What is rock that is changed by heat pressure or chemical change?
Metamorphic rocks have been changed by heat or pressure. This can be a change in size, shape, or arrangement of minerals.
Can an igneous rock become metamorphic?
Yes,so can sedimentary rocks and even other metamorphic rocks.
What are 2 textures of metamorphic rock?
The two textures of metamorphic rocks are the Foliate and Non-foliate textures.
What are two textural divisions of metamorphic rocks and the conditions associated with each?
Metamorphic rocks are generally divided into two textural divisions: foliate and non-foliate. Foliate metamorphic rocks, such as schist and slate, exhibit a layered or banded appearance due to the alignment of mineral grains under directed pressure, typically formed in high-pressure conditions. Non-foliate metamorphic rocks, like marble and quartzite, lack this layered texture and are usually formed under conditions of uniform pressure and high temperature, often from the metamorphism of limestone and sandstone, respectively.
Are metamorphic rocks classified according to their shape?
No, metamorphic rocks are not classified according to their shape. Instead, they are classified based on their mineral composition and texture, which reflects the conditions under which they formed. Common classifications include foliate, which has a layered or banded appearance, and non-foliate, which does not exhibit layering. The classification primarily focuses on the processes of metamorphism and the resulting characteristics of the rocks.
Why are metamorphic rocks foliated while others are not?
In order to foliate, rocks must have pressure along one axis and contain minerals with specific growth patterns
Is granite foliate?
No. Foliation is a texture most often used to describe the banded, platy, or layered appearance of certain metamorphic rocks.
What type of metamorphism forms foliate rocks?
Any rock can undergo metamorphism, be it sedimentary, igneous or even the transformation of one type of metamorphic rock to another.
Is a metamorphic rock with no banding a nonfoliated rock?
Yes, a metamorphic rock with no banding is classified as a nonfoliated rock. Nonfoliated rocks do not exhibit the layering or banding commonly seen in foliated rocks due to the recrystallization process they undergo during metamorphism.
Which foliate metamorphic rock has the smallest crystals?
Slate is a foliate metamorphic rock with the smallest crystals. It forms from the low-grade metamorphism of shale or mudstone, resulting in fine-grained crystals too small to be seen with the naked eye.
Are metamorphic rocks only formed by igneous rocks?
No. Metamorphic rocks can also from front sedimentary rocks and from other metamorphic rocks.
Changed-over rocks are called?
Metamorphic Rocks
Is metamorphic rocks made up of sedimentary rock igneous rock or other metamorphic rocks?
Metamorphic rocks
Are unakite rocks Metamorphic rocks or igneous rocks?
It is a type of Metamorphic rock
