What is foliation 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. hornblende) in this plane. Slate, schist, and gneiss are three common foliated metamorphic rocks.
What is an example of lineation?
Examples of lineations. (a) Bedding-cleavage intersection lineation, (b) crenulation lineation, (c) rodding, (d) mineral lineation defined by coarse actinolite crystals.
What is lineation in structural geology?
Lineation is a general term to describe any repeated, commonly penetrative and parallel alignment. of linear elements within a rock (to envision lineation, imagine packages of spaghetti). A lineation. may be a primary igneous or sedimentary fabric element, such as an array of elongate K-feldspar.
What causes lineation geology?
Lineation may be formed during deformation by the parallel alignment of minerals, fossils, or pebbles; by parallel crenulation cleavages; or by striations and grooves resulting from the movement of a rock over a plane, e.g. a fault surface (see SLICKENSIDE), or flexural slip during folding.
Why is lineation important in poetry?
A reader or auditor need not understand the principle behind each line break intellectually, but he or she must intuitively feel its appropriateness and authority. The purpose of lineation in verse is to establish a rhythm of expectation that heightens the listener’s attention and apprehension.
How is lineation created?
What is lineation where is it formed?
Lineations are a series of parallel lines on a rock surface, formed by tectonic processes, by the transportation and deposition of sand under upper-flow-regime plane-bed conditions, or by the movement of glacial ice over the rock surface.
How would you describe foliation in metamorphic rocks?
Foliated Metamorphic Rocks: (Foliated means the parallel arrangement of certain mineral grains that gives the rock a striped appearance.) Foliation forms when pressure squeezes the flat or elongate minerals within a rock so they become aligned.
What does it mean to alienate someone?
Definition of alienate 1 : to cause to be estranged : to make unfriendly, hostile, or indifferent especially where attachment formerly existed He alienated most of his colleagues with his bad temper.
What is literary lineation?
Lineation in poetry is how lines are divided and where they end in relation to a clause or thought. Having a line break at the end of a phrase or complete thought is a regular and expected pattern in poetry. Poets subvert this expectation by using a technique called enjambment.
What is foliation rock?
(Foliated means the parallel arrangement of certain mineral grains that gives the rock a striped appearance.) Foliation forms when pressure squeezes the flat or elongate minerals within a rock so they become aligned.
What’s a 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.
