Gneiss 4. GEOL 121 mineral-rich fluids. 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.

WebFoliation is defined as a pervasive planar structure that results from the nearly parallel alignment of sheet silicate minerals and/or compositional and mineralogical layering in the rock. Most foliation is caused by the preferred orientation of phylosilicates, like clay minerals, micas, and chlorite. http://www.geo.utexas.edu/courses/420k/PDF_files/LABS/metlab.pdf

WebFoliated rocks are usually formed when there is a significant amount of differential pressure acting on the rock. Put simply, the rock is being squeezed much harder in one direction than in any others. The layers or banding in foliated rocks form perpendicular to the direction of maximum compression. Slate WebFoliation forms when pressure squeezes the flat or elongate minerals within a rock so they become aligned. These rocks develop a platy or sheet-like structure that reflects the …
