Marble Rock Life Cycle

All rocks can be metamorphosed and there are many different types of metamorphic rock.

Marble rock life cycle. The rock cycle is a continuous process describing the transformation of the rocks through various stages throughout their lifetime. Nonfoliated rocks can also form by metamorphism which happens when magma comes in contact with the surrounding rock. Limestone can change into marble shale and mudstones into slate and igneous rocks like granite can turn into gneiss. Commercially it includes all decorative calcium rich rocks that can be polished as well as certain serpentines verd antiques.

Marble is a metamorphic rock that developed from limestone most of the material is calcite a crystalline form of calcium carbonate ca c o 3 and dolomite it is often used for sculpture as a building material and for many other purposes. Each rock has a unique formation process. Petrographically marbles are massive rather than thin layered and consist of a. Formation of marble is explained below.

Whether they are exposed to heat pressure or both. The rocks in the earth s crust continuously undergo changes in their composition which leads to formation of other rocks. It is formed by the metamorphism of limestone. Examples of metamorphic rocks include marble formed from limestone and slate formed from shale.

Metamorphic rocks are grouped into foliated and non foliated metamorphic rocks. 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. The process of rock cycle. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.

The word marble is also used for other stones that can be polished well and for ball shaped objects used for child games. Sedimentary rocks like bituminous coal limestone and sandstone given enough heat and pressure can turn into nonfoliated metamorphic rocks like anthracite coal marble and quartzite.
