C) The process must take place underground. c. Pressure has an important role in the transformation of rocks in contact metamorphism. true. Metamorphism is the transformation of existing rock (the protolith) to rock with a different mineral composition or texture.Metamorphism takes place at temperatures in excess of 150 to 200 C (300 to 400 F), and often also at elevated pressure or in the presence of chemically active fluids, but the rock remains mostly solid during the transformation. B. Contact metamorphism is caused by large-scale geological events. It occurs within the continental crust. These rocks were typically exposed to tectonic forces and associated high pressures and temperatures. The critical feature of the parent rock is its mineral composition.This is because the stability of minerals (how influenced they are by changing conditions) is what counts when metamorphism takes place.
