A metamorphic rock on the other hand began as a rock either a sedimentary igneous or even a different sort of metamorphic rock.
Is marble metamorphic igneous or sedimentary.
The protolith may be an igneous rock or a sedimentary rock or another older metamorphic rock.
The existing rock type which undergoes a change is referred to as the protolith.
Igneous and sedimentary rocks mainly undergo this change and become metamorphic rocks.
Then due to various conditions within the earth the existing rock was changed into a.
Igneous rocks form from the cooling of magma molten materials in the earth s crust.
Based on the rock formations there are three basic classes which include igneous sedimentary and metamorphic.
Hence the study of metamorphic rocks provides an understanding of the pressure and temperatures deep within the earth s crust.
Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.
Each kind of igneous rocks contains different minerals and has different structures.
From the terminology itself igneous means from fire or heat.
Marble the rock is metamorphic.
Igneous rocks comprise about 95 of the total earth s crust.
All other types of rocks viz sedimentary and metamorphic originate from igneous rocks and therefore they are also called primary rocks.
There are many types of igneous rocks.
Their transformation may be physical or chemical requiring great heat and pressure.
Metamorphic rocks are formed from the transformation of an existing rock or original rock called protolith.
