Graphite-pencils. Many economic deposits of gold, copper, tungsten and iron occur in metamorphic rocks.arble is a metamorphic rock that is used to make floor tiles, counter tops and it is carved int â¦ o statues and was used extensively in the building of the Roman Colosseum and other historic buildings.
A metamorphic rock used to be some other type of rock, but it was changed inside the Earth to become a new type of rock. The word metamorphism comes from ancient Greek words for change (meta) and form (morph). The type of rock that a metamorphic rock used to be, prior to metamorphism, is called the protolith. During metamorphism the mineral content and texture of the protolith are changed due to changes in the physical and chemical environment of the rock. Metamorphism can be caused by burial, tectonic stress, heating by magma, or alteration by fluids. At advanced stages of metamorphism, it is common for a metamorphic rock to develop such a different set of minerals and such a thoroughly changed texture that it is difficult to recognize what the protolith was.
