Es wird durch Scherkräfte (Drücke, die verschiedene Abschnitte des Gesteins in verschiedene. 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 We introduced foliation, such as slaty cleavage, schistosity, and gneissic layering, while discussing the effects of metamorphism. Here we add to the story by noting that such foliation forms in response to flattening and shearing in ductilely deforming rocks in other words, foliation indicates that the rock has developed a strain under metamorphic conditions (figure above a, b). Credits. Foliation bedeutet per Definition ein durchdringendes Muster, das auf die Neuausrichtung von Mineralien wie Glimmermineralien zurückzuführen ist. Foliation wird auch verwendet, um das gebänderte physikalische Erscheinungsbild von metamorphen Gesteinen zu beschreiben
Als Foliation (von lat. folia für Blättchen) wird in der Geologie und Mineralogie die Bildung blättriger Flächen bezeichnet. 39 Beziehungen Foliation - fabric-forming planar structure • Primary - forms during deposition of sediments and formation of magmatic rocks • Secondary - product of stress and strain ( tectonic foliation). Examples are cleavage, schistosity, and mylonitic foliations. • Cleavage refers to the ability of a rock to split or cleave into more or less parallel surfaces. Relative age terminology - S o. Deep below the earth's surface resides a type of rock called metamorphic rock. In geology, repeating layers of this rock are called foliation... This kind of foliation is called primary foliation - formed during deposition or igneous crystallization of rocks - to distinguish them from secondary (or tectonic) foliation that develops when rocks are deformed. There is a foliation inside this granitic dyke from the Calamita Peninsula (Elba Island, Italy). In this case it is defined by black bands rich in tourmaline and changes in grain.

Foliation in geology refers to repetitive layering in metamorphic rocks. Alignment of tabular minerals in metamorphic rocks, igneous rocks and intrusive rocks may form a foliation. The layering within metamorphic rocks is called foliation (derived from the Latin word folia, meaning leaves), and it occurs when a rock is being shortened along one axis during recrystallization. Rock (geology. This lecture has classification of different foliation and cleavages. This lecture contain cleavage and bedding relationship also
A foliation is any sort of fabric-forming planar or curved planar geologic structure in a metamorphic rock, but could additionally include sedimentary bedding or magmatic layering (Wilkerson, 2019). A foliated rock holds a parallel alignment of certain minerals that are repetitively layered Planare Gefüge, auch Foliation genannt, entstehen während der Bildung von Gesteinen (= primäre Foliationen) und danach (= sekundäre Foliationen). Der Begriff Foliation ist wertneutral, d.h. nicht mit einer genetischen Interpretation verbunden

Fabric-forming planar structure is called foliation. Foliation is broadly defined as any planar arrangement of mineral grains /structural features in a rock. Structural geologist's definition: Planar fabric is secondaryand due to mineral recrystallization and/or plastic behavior during deformation at elevated temperature Foliation is a term used that describes minerals lined up in planes. Certain minerals, most notably the mica group, are mostly thin and planar by default. Foliated rocks typically appear as if the minerals are stacked like pages of a book, thus the use of the term 'folia', like a leaf. Other minerals, with hornblende being a good example, are longer in one direction, linear like a pencil. Als Unterform der Foliation beschreibt sie daher die Textur eines Gesteins. Je nach Sichtweise kann der Begriff die metamorphe Überprägung einer primären Schichtung oder eines magmatischen Lagengefüges (beispielsweise in Lavaströmen) aus- oder einschließen

The slatey cleavage typical of slate is due to the parallel growth of microscopic mica crystals. In gneiss the foliation is more typically represented by compositional banding due to segregation of mineral phases. Foliated rock is also known as S-tectonite in sheared rock masses.

Foliation, Mineralienatlas Lexiko Sowohl Foliation als auch Schichtung werden für geologische Zwecke verwendet. Foliation . Folierung bedeutet definitionsgemäß ein durchdringendes Muster, das auf die Neuausrichtung von Mineralien wie Glimmermineralien zurückzuführen ist. Foliation wird auch verwendet, um das gebänderte Aussehen von metamorphen Gesteinen zu beschreiben. Metamorphe Gesteinsschichten sind daher ein Produkt. Foliation vs Layering . Folierung und Schichtung sind sowohl in sedimentären als auch in metamorphen Gesteinen als Muster vorhanden. Um den Unterschied zwischen beiden zu erkennen, müssten die verschiedenen Gesteine physikalisch beurteilt werden, indem entweder die Komponenten visuell überprüft oder das Mineral genau betrachtet werden
Reactivation causes rotation or 'refraction'of axial‐plane foliations (forming in the same deformation event causing reactivation) in those beds or zones in which an earlier foliation has been reactivated, and results in destruction of the originally axial‐plane foliation at high strains. Reactivation also provides a simple explanation for the apparently 'wrong sense', but normally. Foliation vs Layering Foliation and layering are the two terms related to the formation of rocks. They differ from each other in a variety of areas. Foliation and layering involve different kinds of rock formation. In sedimentary and metamorphic rocks, foliation and layering is presented as a pattern. Describing the differences between these two may [
