They promote the growth of new minerals by enhancing ion migration. For instance, the presence of fluids facilitates the transformation of limestone to marble. Time: Metamorphism is a process that occurs over geological timescales. The longer the rock is subjected to heat and pressure, the more pronounced the metamorphic transformation.

During the late stage of the dolomitizition process, the porosity formation is the results of excess solution over precipitation (Landes, 1946, Sun, 1992, Purser et al., 1994, Machel, 2004, Wendte, 2006), because precipitation of dolomite from fluids will lead to undersaturation with respect to host limestone (Land, 1991, Machel, 2004).

Limestone is a sedimentary rock which is formed underwater. Some limestone consists mainly of coral or the shells of other small marine creatures. Limestone may also be precipitated from seawater. Limestone is a permeable rock. This means that water can enter limestone through pores, joints or cracks in the rock.
