Igneous rocks can become foliated by alignment of cumulate crystals during convection in large magma chambers, especially ultramafic intrusions, and typically plagioclase laths. Granite may form foliation due to frictional drag on viscous magma by the wall rocks. See more 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 … See more 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 … See more When describing a foliation it is useful to note • the mineralogy of the folia; this can provide information on the conditions of formation • the mineralogy in intrafolial areas See more Foliation, as it forms generally perpendicular to the direction of principal stress, records the direction of shortening.
