WebSep 2, 2024 · Foliation (Latin folium means leaf) is a planar structure given by preferred orientation of minerals generally showing a platy or tabular habit. The preferred … Foliation is usually formed by the preferred orientation of minerals within a rock. Usually, this is the result of some physical force and its effect on the growth of minerals. The planar fabric of a foliation typically forms at right angles to the maximum principal stress direction. In sheared zones, however, planar fabric within a rock may not be directly perpendicular to the principal stress direction due to rotation, mass transport, and shortening.
