Foliated textures can vary in their appearance and composition depending on the minerals present and the degree of metamorphism. Some foliated rocks, such as slate and phyllite, have a fine-grained texture, while others, such as gneiss and schist, have a coarser-grained texture. The foliations can also vary in thickness and may be regular or irregular in their spacing.
Foliated textures are commonly found in metamorphic rocks that have experienced significant pressure and heat, such as those found in mountain belts and collision zones. They are also found in rocks that have undergone shearing or deformation, such as those found near faults.
