Is Granite Igneous Metamorphic Or Sedimentary

Igneous rocks formed when liquid magma or lava magma that has emerged onto the surface of the earth cooled and hardened.

Is granite igneous metamorphic or sedimentary.

There are many types of igneous rocks. Partial melt granitic type rocks are granitic gneiss which is a metamorphic rock. Igneous rock sedimentary rock and metamorphic rock. Then due to various conditions within the earth the existing rock was changed into a.

We have 3 main types or classes of rock based on how they are formed. A metamorphic rock on the other hand began as a rock either a sedimentary igneous or even a different sort of metamorphic rock. Most of the solid surface of our planet ro ughly 70 is represented by sedimentary rocks but if you go deep enough beneath the earth s surface there are plenty of igneous and metamorphic r. Igneous rocks comprise about 95 of the total earth s crust.

The granite melts into lava then cools becoming igneous. All other types of rocks viz sedimentary and metamorphic originate from igneous rocks and therefore they are also called primary rocks. Each kind of igneous rocks contains different minerals and has different structures. The sedimentary rock becomes metamorphic with heat and pressure.

These molten substances are called magma or lava magma can be derived from melting of existing rocks on the earth crust. Igneous and sedimentary rocks mainly undergo this change and become metamorphic rocks. Even the granites that form via metamorphism of sediments are igneous because they pass through a melting stage. Igneous rocks are formed when molten substances below the earth surface cools down and solidifies.

Hence the study of metamorphic rocks provides an understanding of the pressure and temperatures deep within the earth s crust.
