Is Marble An Igneous Rock

Igneous rocks are formed by the cooling and solidification of lava or magma.

Is marble an igneous rock.

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. Sedimentary rocks are created by other rocks or fossils that form deposits on the earth s surface. Occasionally as at carrara. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.

Marbles often occur interbedded with such metamorphic rocks as mica schists phyllites gneisses and granulites and are most common in the older layers of earth s crust that have been deeply buried in regions of extreme folding and igneous intrusion. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. Marble is commonly used for sculpture and as a building material. The change from limestones rich in fossils into true marbles in such metamorphic regions is a common phenomenon.

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.
