Marble is made by regional metamorphism of limestone or dolomite rock causing their microscopic grains to combine into larger crystals.
Foliated metamorphic rocks such as gneiss phyllite schist and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure.
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.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.
Other examples include quartzite hornfels and novaculite.
Examples of metamorphic rocks.
Metamorphic rocks do not melt but the chemicals they contain may change their forms or crystal shapes.
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.
Metamorphic rocks are formed form pre existing rocks through the process of metamorphism.
Slate granite gneiss and biotite schist are strongly banded and foliated.
The extensively known example of non foliated metamorphic rock is a marble.
Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth.
Non foliated metamorphic rocks such as hornfels marble quartzite and novaculite do not have a layered or banded appearance.
Remember these rocks are formed under extreme heat and pressure.
Metamorphic rocks started out as some other type of rock but have been substantially changed from their original igneous sedimentary or earlier metamorphic form.
