👉 Plutonian metamorphism is a process that occurs when rocks are subjected to high temperatures, pressures, and chemical reactions. This process can lead to the transformation of rocks from one phase (such as igneous rock) into another (such as metamorphic rock). The resulting metamorphic rock may have different physical properties than its original phase, such as increased hardness or flexibility. It is an important process in many geological processes, particularly during the formation of mountain ranges and other geological formations.
