What event found at a transform boundary will help from metamorphic rock?

At a transform boundary, the intense pressure and friction generated by the sliding of tectonic plates can lead to the formation of metamorphic rock. This occurs as rocks are subjected to high temperatures and pressures without melting, causing changes in their mineral composition and structure. An example of such an event is the grinding and deformation of rocks along the San Andreas Fault. The resulting metamorphic rocks, such as schist or gneiss, are indicative of the intense geological processes at work in these dynamic environments.
