In geology, solid-state recrystallization is a metamorphic process that occurs under high temperatures and pressures where atoms of minerals are reorganized by diffusion and/or dislocation glide. The mineral composition may remain unchanged. This process can be illustrated by observing how snow recrystallizes to ice.

As opposed to metasomatism, which is a change in composition, recrystallization can be a purely physical process.

Limestone is a sedimentary rock that undergoes metamorphic recrystallization to form marble, and clays can recrystallize to muscovite mica.
