Metamorphic processes or Metamorphism can takes place anywhere, be it above or below the Earths surface, as long as their is a change in the physicochemical (structural and minerological) conditions different from that under which the rocks were originally formed. And this could be as a result of adjustment of solid rocks to increased temperature, pressure and/or chemical activities (chemically active fluids).
Metamorphic rocks can be classified by type of metamorphism. Regional metamorphism is caused by pressures and heat derived from plate movement processes. Contact metamorphism is caused from proximity to an intrusive plutonic body. Metamorphic rocks are also classified by degree of metamorphism, expressed as a grade (low, medium, high), as a rock experiences higher and higher heat and pressure until it eventually melts.
It is played as a solumential guidence fluid that flows through the rock to give it its color
Pressure, Heat, Chemically active fluids (water and CO2 in rocks), Time(obviously), and the parent rock composition.

Heat, Pressure, and Chemically active fluids.
The primary agent of contact metamorphism is heat. Pressure and chemically active fluids are also very important in this process.
Weathering is the decomposition of earth rocks, soils and their minerals through direct contact with the planet's atmosphere. Metamorphism is the solid-state recrystallisation of pre-existing rocks due to changes in heat, pressure, and/or introduction of fluids. SImply put, weathering is the break down of rock (wear and tear) and Metamorphism is rock changing due to Heat,Pressure, and Chemically active fluids

Metamorphism
Hot water rising through cracks, chemically active fluids, pressure from overhead rocks.

Metamorphism is the solid-state recrystallization of pre-existing rocks due to changes in physical and chemical conditions, primarily heat, pressure, and the introduction of chemically active fluids. Mineralogical, chemical and crystallographic changes can occur during this process. Changes at or just beneath Earth's surface due to weathering and/or diagenesis are not classified as metamorphism.Three types of metamorphism exist: contact, dynamic and regional. Metamorphism produced with increasing pressure and temperature conditions is known as prograde metamorphism. Conversely, decreasing temperatures and pressure characterizeretrograde metamorphism.Metasomatism is the chemical alteration of a rock by hydrothermal and other fluids. Metasomatism can occur via the action of hydrothermal fluids from an igneous or metamorphic source.In the igneous environment, metasomatism creates skarns, greisen, and may affect hornfels in the contact metamorphic aureole adjacent to an intrusiverock mass. In the metamorphic environment, metasomatism is created by mass transfer from a volume of metamorphic rock at higher stress andtemperature into a zone with lower stress and temperature, with metamorphic hydrothermal solutions acting as a solvent. This can be envisaged as the metamorphic rocks within the deep crust losing fluids and dissolved mineral components as hydrous minerals break down, with this fluid percolating up into the shallow levels of the crust to chemically change and alter these rocks.Because metasomatism is a mass transfer process, it is not restricted to the rocks which are changed by addition of chemical elements and minerals or hydrous compounds. In all cases, to produce a metasomatic rock some other rock is also metasomatised, if only by dehydration reactions with minimal chemical change.
