mid way down this page there is a table which shows the different pressures and temperatures which produce different types of metamorphic rock

most text books of metamorphism will have a similar chart to this one.

All rock on Earth started out as sedimentary when you take into consideration how the planet was formed. The answer is gravitational pressure compresses the rock.

The process in which a sedimentary rock becomes metamorphised are through pressure, temperature and depth.
