Is Marble Metamorphic Igneous Or Sedimentary

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

Is marble metamorphic igneous or sedimentary.

Igneous rocks comprise about 95 of the total earth s crust. 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. Igneous and sedimentary rocks mainly undergo this change and become metamorphic rocks.

Their transformation may be physical or chemical requiring great heat and pressure. 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. Metamorphic rocks are formed from the transformation of an existing rock or original rock called protolith.

From the terminology itself igneous means from fire or heat. 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. Then due to various conditions within the earth the existing rock was changed into a.

All other types of rocks viz sedimentary and metamorphic originate from igneous rocks and therefore they are also called primary rocks. The protolith may be an igneous rock or a sedimentary rock or another older metamorphic rock. Marble the rock is metamorphic. The existing rock type which undergoes a change is referred to as the protolith.
