Is Marble An Igneous Rock

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.

Is marble an igneous rock. The change from limestones rich in fossils into true marbles in such metamorphic regions is a common phenomenon. Limestone is a sedimentary rock and does not turn into igneous rock but can be metamorphosed to form metamorphic rocks such as marble. Occasionally as at carrara. Marble is commonly used for sculpture and as a building material.

Igneous rocks are formed by the cooling and solidification of lava or magma. A good example of an igneous rock is granite. 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. 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.

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