Limestone Into Marble

When the heat and pressure hits the limestone calcite seed crystals form.

Limestone into marble.

Marble is commonly used for sculpture and as a building material. With continued metamorphism these crystal seeds grow while any clay deposits in the limestone transform into silicate structures such as mica. Limestone change into marble when a great heat and pressure come from the under of the earth change into marble. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.

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. It is composed primarily of the mineral calcite caco3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite. Limestone is hard enough to resist weathering but usually soft enough to be worked cut and carved by stonemasons. 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.

When limestone is heated to a high temperature and squeezed at the base of a mountain it recrystallizes into the metamorphic rock marble marbles are fairly dense relatively easy to cut or be shaped into blocks and some forms are white in colour. Because marble is a fairly soft material only a three on the mohs hardness scale it is easy to cut and carve. It is metamorphic and is usually used as building material and in sculptures. Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral foraminifera and molluscs its major materials are the minerals calcite and aragonite which are different crystal forms of calcium carbonate caco 3 a closely related rock is dolomite which contains a high percentage of the mineral dolomite camg co 3 2.
