What minerals that make up marble. Typically marble is composed of the following major constituents. The purest calcite marble is white in colour. The minerals that result from impurities give marble a wide variety of colors. 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.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Marble does not split easily into sheets of equal size and must be mined with care. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. Grain size medium grained.

Marble containing hematite are reddish in color. Can see interlocking calcite crystals with the naked eye. Marble that has limonite is yellow and marble with serpentine is green in colour. Marble is commonly used for sculpture and as a building material.

Hardness hard although component mineral is soft calcite is 3 on moh s scale of hardness. What is meant by impurities is that the marble will. 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. Mineral impurities in marble can include quartz tremolite actinolite chert garnet biotite muscovite microline talc and fosterite.

Colour variable pure marble is white but marble exists in a wide variety of colours all the way through to black. 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.
