What Is Foliation

The specimen shown above is a chlorite schist because it contains a significant amount of chlorite. It is caused by shearing forces pressures pushing different sections of the rock in different directions or differential pressure higher.

Physical Geology Metamorphic Rocks Foliated Rocks And Non

Schist is a metamorphic rock with well developed foliation.

What is foliation. It is a rock of intermediate metamorphic grade between phyllite and gneiss. Foliation is exhibited most prominently by sheety minerals. Foliation is a ubiquitous cemented weak plane and it could not be regarded as a cohesionless discontinuity.

It often contains significant amounts of mica which allow the rock to split into thin pieces. Decoration with sculpted or painted foliage. 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 the equivalence classes are called the leaves of the foliation.

Each layer can be as thin as a sheet of paper or over a meter in thickness. Architecture decoration of an opening with cusps and foils as in gothic tracery. Foliation in geology refers to repetitive layering in metamorphic rocks.

The act or process of coating glass with metal foil. Foliation definition the act or process of putting forth leaves. The state of being in leaf.

Few studies report the behaviour of a single foliation and its strength and deformability are still unclear. Decoration with sculpted or painted foliage. 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.

The word comes from the latin folium meaning leaf and refers to the sheet like planar structure. The act process or product of forming metal into thin leaf or foil. Foliation definition is the process of forming into a leaf.

However most failure criteria of the weak plane in rock mechanics are only suitable for a cohesionless rough weak plane. The state of being in leaf. Foliation synonyms foliation pronunciation foliation translation english dictionary definition of foliation.

A process in which rocks divide into thin layers that can be separated or the layers. Architecture decoration of an opening with cusps and foils as in.
