Rocks are an aggregate of one or more minerals held together by chemical bonds.
Is granite metamorphic sedimentary or igneous.
Each kind of igneous rocks contains different minerals and has different structures.
The scientific study of rocks is called petrology.
Partial melt granitic type rocks are granitic gneiss which is a metamorphic rock.
Igneous metamorphic and sedimentary the three main types of geological rocks are described.
A metamorphic rock on the other hand began as a rock either a sedimentary igneous or even a different sort of metamorphic rock.
Rocks can be classified in to three main groups igneous sedimentary and metamorphic.
There are many types of igneous rocks.
The types of rock.

Unakite is a metamorphosed granite composed of green epidote and pink orthoclase.
Igneous rocks solidified from magma and lava.
The sedimentary rock becomes metamorphic with heat and pressure.
Granite type rocks granitoids are abo.
It erodes into sediment and then gets compressed into a sedimentary rock.

Now compare it to the granite.
Igneous rocks comprise about 95 of the total earth s crust.
The key difference between igneous rocks and metamorphic rocks is that igneous rocks are the oldest rocks on earth while metamorphic rocks are derivatives of igneous rocks and sedimentary rocks.
Igneous and sedimentary rocks mainly undergo this change and become metamorphic rocks.
All other types of rocks viz sedimentary and metamorphic originate from igneous rocks and therefore they are also called primary rocks.
Then due to various conditions within the earth the existing rock was changed into a.
Igneous rocks formed when liquid magma or lava magma that has emerged onto the surface of the earth cooled and hardened.
Hence the study of metamorphic rocks provides an understanding of the pressure and temperatures deep within the earth s crust.
These three different rock types can be found in distinct areas of the uk.
