What characteristics make marble a useful metamorphic rock explain.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Explain what characteristics make marble a useful metamorphic rock. 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. However foliation and lineation are two characteristics commonly seen in metamorphic rocks and are used to help.

The composition of the rocks as well as the temperature and amount of pressure placed on them all play a role in the type of metamorphic rock formed. Slate is another common metamorphic rock that forms from shale. Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite marble is typically not foliated although there are exceptions in geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Because marble has a fine even grain it is relatively easy to cut into thin slabs.

And marble can be easily polished. A pure marble is composed entirely of the mineral calcite caco3 and has much the same characteristics as a mature crystalline limestone useful for sculpure as well as use as a building stone. Calcite is a relatively soft mineral moh s scale of hardness 3 but this does not deter its use for building is a very positive factor in regard. Marble is a granular metamorphic rock it is derived from limestone or dolomite and it consists of a mass of interlocking grains of calcite or the mineral dolomite.

Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth. Marble is massive that is to say not foliated layered which means that it does not easily crack or split. Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met. Marble is commonly used for sculpture and as a building material.

Form of it when limestone buried deep in the older layers of earth s crust is subjected to heat and pressure from thick layers of overlying sediments. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat.
