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.

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 commonly used for sculpture and as a building material. Occasionally as at carrara.

Igneous rocks are formed by the cooling and solidification of lava or magma. Limestone is a sedimentary rock and does not turn into igneous rock but can be metamorphosed to form metamorphic rocks such as marble. 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.

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.
