Foliation (geology) - Wikipedia
Foliation in geology refers to repetitive layering in metamorphic rocks. [1] Each layer can be as thin as a sheet of paper, or over a meter in thickness. [1] The word comes from the Latin folium, meaning "leaf", and refers to the sheet-like planar structure. [1] It is caused by shearing forces (pressures pushing different sections of the rock ...

Foliation, planar arrangement of structural or textural features in any rock type but particularly that resulting from the alignment of constituent mineral grains of a metamorphic rock of the regional variety along straight or wavy planes. Foliation is …
Foliation - Wikipedia
In mathematics (differential geometry), a foliation is an equivalence relation on an n-manifold, the equivalence classes being connected, injectively immersed submanifolds, all of the same dimension p, modeled on the decomposition of the real coordinate space R n into the cosets x + R p of the standardly embedded subspace R p.

Jun 5, 2020 · Foliation. on an $ n $- dimensional manifold $ M ^ {n} $. A decomposition of $ M ^ {n} $ into path-connected subsets, called leaves, such that $ M ^ {n} $ can be covered by coordinate neighbourhoods $ U _ \alpha $ with local coordinates $ x _ \alpha ^ {1} \dots x _ \alpha ^ {n} $, in terms of which the local leaves, that is, the connected ...
10.2: Foliation and Rock Cleavage - Geosciences LibreTexts
Aug 22, 2024 · The pattern of aligned crystals that results is called foliation. Foliation can develop in a number of ways. Minerals can deform when they are squeezed (Figure 10.5), becoming narrower in one direction and longer in another.

Foliation. Many metamorphic rocks are characterized by the presence of planar structures that repeat themselves parallel to one another within the rocks and are visible at the meso- to the microscale.

Sep 2, 2022 · Foliation is a planar structure showing preferred orientation of minerals with a platy or tabular habit. The preferred orientation is produced by deformation and is uniformly pervasive in a rock. Foliation is developed in metamorphic rocks, and it includes cleavage, schistosity, gneissosity and gneissic banding.
