Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite.
Marble is a rock resulting from metamorphism of sedimentary carbonate rocks, (most commonly limestone or dolomite rock). Metamorphism causes variable recrystallization of the original carbonate mineral grains.
The resulting marble rock is typically composed of an interlocking mosaic of carbonate crystals. Primary sedimentary textures and structures of the original carbonate rock (protolith) have typically been modified or destroyed.
Pure white marble is the result of metamorphism of a very pure (silicate-poor) limestone or dolomite protolith. The characteristic swirls and veins of many colored marble varieties are usually due to various mineral impurities such as clay, silt, sand, iron oxides, or chert which were originally present as grains or layers in the limestone.
Green coloration is often due to serpentine resulting from originally high magnesium limestone or dolostone with silica impurities. These various impurities have been mobilized and recrystallized by the intense pressure and heat of the metamorphism.
Marble is a pure calcium carbonate in equilibrium. Assuming that suitable conditions to melt the marble could end up with carbonate magma which would form carbonatite attained, you would end.
Marble is metamorphosed limestone.
deep in the earth
they thought the metallic plates of the earths crust rubs together and pushes the earth up
Marble is a metamorphic rock so it was formed by heat and pressure. :)
a volcanic mountain is a cone shaped mountain formed when molten rocks erupts from a hole in the earths crust.
. Feldspar is formed throught a process in witch immense heat and pressure over a mperiod of time turns to a mineral. This process usually happens in the mantle. The mineral can also form in natural places, and it makes up 60% of Earths crust. Feldspar can be formed almost anywhere.
New ocean crust is formed at mid-ocean ridges where tectonic plates are diverging (spreading apart).

The Extrusive igneous rock is formed on the earths surface while the Intrusive igneous rock is formed within or inside the earths crust.

most volcanoes are formed from a hot spot in the earths crust.
