Is Marble Metamorphic Igneous Or Sedimentary

Igneous rocks form from the cooling of magma molten materials in the earth s crust.

Is marble metamorphic igneous or sedimentary.

Their transformation may be physical or chemical requiring great heat and pressure. Igneous rocks comprise about 95 of the total earth s crust. The existing rock type which undergoes a change is referred to as the protolith. Talc is a mineral and is not classified as metamorphic sedimentary or igneous as are rocks.

Metamorphic rocks are formed from the transformation of an existing rock or original rock called protolith. 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. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Based on the rock formations there are three basic classes which include igneous sedimentary and metamorphic.

Each kind of igneous rocks contains different minerals and has different structures. Marble the rock is metamorphic. A metamorphic rock on the other hand began as a rock either a sedimentary igneous or even a different sort of metamorphic rock. The protolith may be an igneous rock or a sedimentary rock or another older metamorphic rock.

From the terminology itself igneous means from fire or heat. There are many types of igneous rocks. Hence the study of metamorphic rocks provides an understanding of the pressure and temperatures deep within the earth s crust. Igneous and sedimentary rocks mainly undergo this change and become metamorphic rocks.
