Foliation in geology refers to repetitive layering in metamorphic rocks. Each layer can be as thin as a sheet of paper, or over a meter in thickness. The word comes from the Latin folium, meaning "leaf", and refers to the sheet-like planar structure. It is caused by shearing forces (pressures pushing different sections of the rock in different directions), or differential pressure (higher pressure from o… WebFoliated textures produced by shearing and breaking, such as in a fault zone or a meteor impact crater, are referred to as mylonitic. Non-Foliated Metamorphic Rocks In this texture the mineral crystals in the rock have grown in many directions and do not show alignment.
