A porphyroblast is a large crystal that forms within a finer-grained metamorphic rock, typically during the process of metamorphism. These minerals grow larger than the surrounding matrix due to their slower crystallization, often resulting in a distinct textural contrast. Common examples of porphyroblasts include garnet, staurolite, and kyanite. Their presence can provide important information about the conditions and history of the metamorphic environment.
