It forms from both the chemical precipitation of calcium carbonate and the transformation of shell coral fecal and algal debris into calcite during diagenesis.
Calcite limestone marble.
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.
If the limestone is pure a white marble is formed.
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.
Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.
Marble is a metamorphic rock formed by the alteration of limestone by heat and pressure.
Limestones may include layers of clay or sand which may form the attractive flow banding and colours found in decorative marble.
If the limestone is pure a white marble is formed.
Calcite as limestone and marble.
