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.
What characteristics make marble a useful metamorphic rock explain.
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.
Explain what characteristics make marble a useful metamorphic rock.
Marble is commonly used for sculpture and as a building material.
Because marble has a fine even grain it is relatively easy to cut into thin slabs.
In its pure form marble is a white stone with a crystalline and sugary appearance consisting of calcium carbonate caco 3 usually marble contains other minerals including quartz graphite pyrite and iron oxides these minerals can give marble a pink brown gray green or variegated coloration.
Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat.
Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.
For this reason metamorphic rocks can take on all types of colors and textures.
Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth.
Explain what characteristics make marble a useful metamorphic rock.
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.
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 massive that is to say not foliated layered which means that it does not easily crack or split.
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.
Slate is another common metamorphic rock that forms from shale.
And marble can be easily polished.
Following are examples of three metamorphic rocks and a list of their uses marble is a metamorphic rock that is used to make floor tiles counter tops and it is carved into statues and was used.
