	Types of Metamorphism
		Foliation is generally caused by a preferred orientation of sheet silicates.
		Foliation 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.
		Thus, slatey cleavage or foliation is often seen to be parallel to the axial planes of folds, and is sometimes referred to axial plane cleavage or foliation.

	Foliation (Site not responding. Last check: 2007-10-18)
		In mathematics, a foliation structure on a manifold M gives it stripes.
		For example if the dimension of M is two, there is a pattern of stripes on the Euclidean plane formed by all lines parallel to the x-axis (lines y = c), and a foliation on M is a consistent way of identifying patches on M with such a striped pattern.
		There is a global foliation theory, because topological constraints exist.

	Foliation - Wikipedia, the free encyclopedia
		In mathematics, a foliation is a geometric device used to study manifolds.
		Informally speaking, a foliation is a kind of "clothing" worn on a manifold, cut from a stripy fabric.
		an n − p dimensional subbundle of the tangent bundle of a manifold) to be tangent to the leaves of a foliation, are that the set of vector fields tangent to the distribution are closed under Lie bracket.

		Foliation diminishes in intensity in the same direction, away from the 'straight' belts, but the lineation is equally well developed in both zones.
		Foliation in the meter-scale fold domains transects fold limbs, and is not parallel to the fold axial plane.
		The foliation is continuous with the penetrative foliation in the outcrop, and it transects folds continuously without disruption across fold limbs.

		Foliation = a sheet-like, parallel planar arrangement of minerals in the rock.
		The foliation is less visible on the cut face to the lower left.
		Schist = a medium- to coarse-grained, well foliated rock in which the grains are easily seen and identified by eye or with a hand lens.

	Textures of Metamorphic Rocks
		Foliation - any planar set of minerals, or banding of mineral concentrations, especially the planar structure that results from flattening of the mineral grains, like micas.
		A pervasive, parallel foliation (layering) of fine-grained platy minerals (chlorite) in a direction perpendicular to the direction of maximum stress.
		In a hand sample the foliation can be easily seen, and ususally runs planar through the rock; that is, it all runs the same direction.

	Foliation (geology) - Wikipedia, the free encyclopedia
		Foliation is common to rocks affected by regional metamorphic compression typical of orogenic belts.
		Foliation may be formed by realignment of micas and clays via physical rotation of the minerals within the rock.
		Often this foliation is associated with diagenetic metamorphism and low-grade burial metamorphism.

	Aspects of Foliation Theory - ESI 2002 Abstracts
		In the case of foliated bundles, we illustrate a related theorem asserting the vanishing of the tangential singular cohomology, by using methods in homological algebra.
		The theory is applied to foliations tangent to the characteristic direction of $(M, \theta)$ and orthogonal to a semi-Levi foliation, and to flows obtained by integrating infinitesimal pseudohermitian transformations on a nondegenerate CR manifold.
		A transverse Calabi-Yau structure on a manifold is a transversely holomorphic foliation with trivialized canonical bundle.

	Crustal Deformation
		Foliation is a sheetlike structure that forms when rocks are deformed.
		Foliation can form when flattening causes platy mineral grains to align, much the way toothpicks would be aligned when swept up by a broom.
		Therefore, foliation in deformed rocks is generally parallel to the axial plane of the fold.

	deseretnews.com \| Rocks tell a story of upheavals
		At the time the foliations occurred, the Pequops — in the East Humboldt Range region — were part of a mountain belt called the Sevier orogeny that extended across Utah and Nevada.
		They discovered the second foliation, which was less dominant than the first, when they noticed a line of tiny minerals embedded in the rock along one of the layers.
		They believe the foliation that they discovered was formed as rocks were pushed together in what is called thrusting.

	AMCA: Continuity of the uniformization function of linear foliation on three-dimensional torus with nonstandard metric ...
		In the simplest case, when the leaves of the foliation F are tori, the answer to this question is positive.
		For a foliation F satisfying a Diophantine condition we prove an analogue of Riemann mapping theorem.
		One can provide examples of foliations F as at the beginning of the abstract with dense leaves such that for a generic analytic metric the statement of Lemma 2 is false.

		The foliation is usually perpendicular to the direction of the applied stress.
		The amount of recrystallization in a regionally metamorphosed rock is a function of the magnitudes of the heat and pressure at which the process occurs.
		Rocks produced by contact metamorphism do not have a foliated texture (unless the original rock was foliated) and appear sugary.

	Metamorphic Rocks (Site not responding. Last check: 2007-10-18)
		The generally-crude layering or foliation of many metamorphic rocks is due to the intense directional pressure they experienced while buried deep underground, usually along a convergent plate tectonic boundary.
		This banding develops a crude sort of foliation, typically as alternating layers of light minerals (quartz and feldspar) and dark minerals (hornblende and biotite mica).
		As opposed to the foliated metamorphic rocks, the nonfoliated rocks are not distinctly layered.

	Find a Fold Axis From the Intersection of Bedding and Foliation (Site not responding. Last check: 2007-10-18)
		However, fanning foliation usually is still parallel to the fold axis so the method of finding the fold axis from the intersection of bedding and foliation can still be applied.
		If you have a locality where the foliation is vertical (as it often is) and the strike of the bedding is perpendicular to it, the foliation defines the trend of the fold axis and the dip of the bedding defines the plunge.
		The intersection of bedding and foliation defines the fold axis, and if the bedding is perpendicular to the foliation then the intersection is down the dip of the bed.

		In the Reeb foliation, there is one torus leaf, and the other leaves are topological disks which fill two solid tori.
		The disks can be taken to be perpendicular to the core of each solid torus, but bending so that they spin infinitely about the solid torus in one direction, so that they are close to flat near the torus.
		Any time one has a circle transverse to a 2-dimensional foliation, one can "spoil" the foliation by replacing a neighborhood of the circle by a neighborhood of one solid torus of the Reeb foliation.

	Visual glossary of geologic terms - foliation (Site not responding. Last check: 2007-10-18)
		Foliation forms when pressure squeezes flat or elongate minerals within a rock so they become aligned.
		These rocks develop a platy or sheet-like structure that reflects the direction that pressure was applied in.
		Slate, schist, and gneiss (pronounced 'nice') are all foliated metamorphic rocks.

		Foliation in a gneiss is called gneissic banding, and mica is not the dominant mineral and does not form the foliation.
		Foliation in a schist is called schistosity, and mica is the dominant mineral.
		Neither gneisses nor schists are foliated because they are igneous rocks.

		There are some situations where knowing something about the foliations that exist on a manifold does say something about the structure of the manifold, but (as often happens) we get caught up with these issues about foliations themselves.
		Now, I want to find a codimension-one foliation of the solid torus, including the boundary (the torus itself) as a leaf.
		This, along with the boundary (which is now a torus) gives a foliation of the solid torus (called a Reeb component).

		A style of leather binding developed in France during the late 16th and early 17th centuries, featuring interlaced ribbons dividing nearly the entire surface of the covered boards into compartments of various shapes, each filled with small tooled foliate designs, except for the compartment in the center.
		Geoffrey Glaister notes in Encyclopedia of the Book (Oak Knoll/British Library, 1996) that the interlace was typically bounded by a single line on one side and a double line on the other (click here and here to see examples).
