Characteristic foliation
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, … 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, as it forms generally perpendicular to the direction of principal stress, records the direction of shortening. This is related to the axis of folds, which generally form an … See more In geotechnical engineering a foliation plane may form a discontinuity that may have a large influence on the mechanical behavior (strength, deformation, etc.) of rock masses in, for example, tunnel, foundation, or slope construction. See more When describing a foliation it is useful to note • the mineralogy of the folia; this can provide information … See more • Cleavage (geology) • Discontinuity (geotechnical engineering) • Exfoliating granite • Fissility (geology) • Fold (geology) See more WebThe foliation sweeps around a sigma porphyroclast in a somewhat rhombic shape, rather like a “small island of S-plane” in a sea of C-plane. Just like C-S fabric it can therefore …
