Marble Rock: Geology, Properties, Uses - ThoughtCo

Dec 02, 2019  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.

Geology - rocks and minerals

Marble Marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals. The variety of colours exhibited by marble are a consequence of minor amounts of impurities being incorporated with the ...
