Where there is directed pressure on a rock metamorphism made?

Directed pressure during metamorphism occurs when stress is applied unevenly, often leading to foliation in the rock's structure. This type of pressure can result from tectonic forces, such as those found at convergent plate boundaries. The increased temperature and pressure conditions facilitate the recrystallization of minerals, causing changes in the rock's texture and composition. As a result, metamorphic rocks like schist and gneiss often form under these conditions, displaying distinct layering or banding.
