<P> The change in the particle size of the rock during the process of metamorphism is called recrystallization . For instance , the small calcite crystals in the sedimentary rock limestone and chalk change into larger crystals in the metamorphic rock marble ; in metamorphosed sandstone , recrystallization of the original quartz sand grains results in very compact quartzite , also known as metaquartzite , in which the often larger quartz crystals are interlocked . Both high temperatures and pressures contribute to recrystallization . High temperatures allow the atoms and ions in solid crystals to migrate , thus reorganizing the crystals , while high pressures cause solution of the crystals within the rock at their point of contact . </P>
