Is Marble Metamorphic Igneous Or Sedimentary

The protolith may be an igneous rock or a sedimentary rock or another older metamorphic rock.

Is marble metamorphic igneous or sedimentary.

Marble the rock is metamorphic. Their transformation may be physical or chemical requiring great heat and pressure. All other types of rocks viz sedimentary and metamorphic originate from igneous rocks and therefore they are also called primary rocks. Igneous and sedimentary rocks mainly undergo this change and become metamorphic rocks.

Hence the study of metamorphic rocks provides an understanding of the pressure and temperatures deep within the earth s crust. Each kind of igneous rocks contains different minerals and has different structures. It is composed primarily of the mineral calcite caco 3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is. A metamorphic rock on the other hand began as a rock either a sedimentary igneous or even a different sort of metamorphic rock.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Then due to various conditions within the earth the existing rock was changed into a. Talc is a mineral and is not classified as metamorphic sedimentary or igneous as are rocks. Igneous rocks form from the cooling of magma molten materials in the earth s crust.

There are many types of igneous rocks. Igneous rocks formed when liquid magma or lava magma that has emerged onto the surface of the earth cooled and hardened. The existing rock type which undergoes a change is referred to as the protolith. From the terminology itself igneous means from fire or heat.
