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.
Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat.
Marble is commonly used for sculpture and as a building material.
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.
Commercially it includes all decorative calcium rich rocks that can be polished as well as certain serpentines verd antiques.
Any limestone pure or impure can recrystallize as a marble.
Marble has a uniform texture non foliated.
It was a sedimentary rock before it was metamorphosed.
All that is required is some combination of high temperature and high pressure enough time for the recrystallization to take pl.
