Is Marble An Igneous Rock

Sedimentary rocks are created by other rocks or fossils that form deposits on the earth s surface.

Is marble an igneous rock.

The change from limestones rich in fossils into true marbles in such metamorphic regions is a common phenomenon. A good example of an igneous rock is granite. 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 that forms when limestone is subjected to the heat and pressure of metamorphism.

Limestone is a sedimentary rock and does not turn into igneous rock but can be metamorphosed to form metamorphic rocks such as marble. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. 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. Occasionally as at carrara.

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