How long does it take to turn limestone into marble?

Answer 1

Marble is a metamorphic rock with a parent rock of limestone or dolostone and is formed by natural processes by heat and pressure. The heat may be derived by proximity to a magmatic intrusion or from depth of burial.

Answer 2

Marble forms from the metamorphism of limestone or dolostone. The metamorphism occurs as a result of exposure to heat and pressure over large expanses of time. Without melting, the constituent minerals, mainly calcite or dolomite, recrystallize into larger interlocking mineral crystals. The heat and pressure is usually a result of limestone being caught in the processes of plate tectonics, specifically, the collisions of two tectonic plates. Occasionally, marble is formed from contact metamorphism, the result of limestone exposure to heat from a source of magma.

Answer 3

Marble is a metamorphic(characterized by change of form) limestone. When the limestone is heated and pressure is put on it, the calcite(CaCO3) in it melts. If the limestone was pure before heat or pressure was applied to it, a white marble will be obtained. If it had hematite or haematite(iron oxide, Fe2O3) or clay in it, reddish marble will be obtained.

Answer 4

The metamorphism would be a process that would envelop millions of years.

Answer 5

Millions of years.

Answer 6

Marble can last up to 3-4 centuries
