Is Marble An Igneous Rock

The change from limestones rich in fossils into true marbles in such metamorphic regions is a common phenomenon.

Is marble an igneous rock.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. 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. Igneous rocks are formed by the cooling and solidification of lava or magma. A good example of an igneous rock is granite.

Occasionally as at carrara. 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. 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.

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