Are bedding and foliation the same thing?
As nouns the difference between bedding and foliation is that bedding is the textiles associated with a bed, eg, sheets, pillowcases, bedspreads, blankets, etc while foliation is the process of forming into a leaf or leaves.
What is the difference between foliation and lineation?
Foliation is the result of the parallel arrangement of (micas, etc.) in a plane perpendicular to the maximum principal applied stress. A lineation is caused by a similar growth of elongate minerals (eg. Slate, schist, and gneiss are three common foliated metamorphic rocks.
How is metamorphic foliation related to sedimentary bedding?
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. Foliation may parallel original sedimentary bedding, but more often is oriented at some angle to it.
What is meant by the term foliation?
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.
What is secondary foliation?
A foliation that develops during deformation and/or metamorphism; includes slaty cleavage, crenulation cleavage, solution cleavage, schistosity, and gneissic banding.
What is the scientific definition of cross bedding?
noun. geology layering within one or more beds in a series of rock strata that does not run parallel to the plane of stratificationAlso called: false bedding.
How is cross bedding related to sedimentary rock?
Sedimentary rock strata at differing angles. In geology, cross-bedding, also known as cross-stratification, is layering within a stratum and at an angle to the main bedding plane. The sedimentary structures which result are roughly horizontal units composed of inclined layers.
What kind of environment does cross bedding occur in?
Cross-bedding is widespread in three common sedimentary environments: rivers, tide-dominated coastal and marine settings. What was the original environment? In the Jacobsville Sandstone at Hungarian Falls we interpret a river.
How are cross beds formed in an aeolian environment?
In an aeolian environment, cross beds often exhibit inverse grading due to their deposition by grain flows. Winds blow sediment along the ground until they start to accumulate. The side that the accumulation occurs on is called the windward side. As it continues to build, some sediment falls over the end.
Which is an example of a cross bed?
Crossbedding. Cross-beds are the groups of inclined layers, and the sloping layers are known as cross strata. Cross bedding forms on a sloping surface such as ripple marks and dunes, and allows us to interpret that the depositional environment was water or wind. Examples of these are ripples, dunes, sand waves, hummocks, bars, and deltas.
