Definition of lineation in US English:

    • ‘The insistent lineation sifts sentences into phrases and words, so that ‘Bolt,’ ‘Grounds,’ and ‘Chips’ can be read as either nouns or verbs.’
    • ‘It is as if just by isolating language on the page, introducing a certain spacing and lineation, the words are made to speak in a new way.’
    • ‘That is, the space and lineation achieve aural and visual effects which materially reinforce the poetic message of bleakness.’
    • ‘The counterpoint between lineation and grammar in a poem may itself be subject to a further articulation, thought, which as its own periods are superimposed introduces new patterns of reduction and amplification.’
    • ‘So too with any great tradition of poetry: we must have a place to start, the conventions of lineation, and along with them conventions of stanza, poetic form, and chapter.’
    • ‘It would be awkward to respect written lineation sometimes and to ignore it at other times.’
    1. 1.1 A line or linear marking; an arrangement or group of lines.
      ‘magnetic lineations’
      • ‘It further supportis the idea that the magnetic lineations represent the stretching direction of the deforming magma.’
      • ‘Even at ocean - ocean subduction zones, one plate is destroyed, together with the record of magnetic lineations carried on it.’
      • ‘However, bedding-cleavage intersection lineations for this regionally developed cleavage display distinctly different distributions when plotted in stereographic projection.’
      • ‘Magnetic foliations and lineations obtained from these sites can be interpreted directly in terms of structural information.’
      • ‘Faint and fine suturai lineations, incompletely reflecting tabulation, variably developed over surface.’
      • ‘Magnetic lineations indicate that the continents were completely separated 90 million years ago, and these authors suggest a date probably 5 to 10 million years earlier.’
    2. 1.2 A contour or outline.
      • ‘Most of the granitic plutons that make up this part of the batholith are characterized by upright magmatic-state planar fabrics trending NE with shallow lineations.’
      • ‘Magnetic surveys of Watts et al. and Davey in the South Fiji Basin identified anomaly lineations 12-7A; Malahoff et al. suggested that anomaly 13 is locally present.’
      • ‘The lineations plunge to the north in the northern part of the island and to the south in the southeastern part.’
      • ‘Biotite and amphibole lineations on the cleavage plane plunge consistently SW or WSW.’
      • ‘Chlorite and quartz stretching lineations plunge in a SW or WSW direction.’
      • ‘Quartz and chlorite stretching lineations show two major trends, either down dip to the SW or sub-horizontal plunge to the west or NW, i.e. along strike.’
      • ‘Their lineations, which are not influenced by the intrusion boundaries, faithfully reflect the stretching direction of the tectonic regime coeval with magma emplacement and cooling.’
      • ‘Thus there is commonly a stretching lineation visible on fabric planes that indicates the movement direction, at least during the final stages of fabric development.’
      • ‘Albite porphyroblasts and associated greenschist-facies fabrics are folded by crenulations related to late-stage east-trending folds, lineations associated with which plunge shallowly towards east or west.’
      • ‘Hornblende forms elongate prisms that define a lineation together with plagioclase.’
      • ‘The lineations show shallow easterly plunges in the north becoming steeper in the south of the Welverdiend shear zone.’
      • ‘The c-axis and e-lamellae pole figures also display a great circle girdle normal to the lineation, which decreases in intensity with increasing strain.’
      • ‘The lineations on the flanks of these ‘folds' trend N110 - N140 whereas they converge southeastward close to the fold hinge.’
      • ‘The angle between a pair of equivalent marker lineations on a sphere constrains the rotation pole to lie on a great circle that is perpendicular to the mutual plane of those lineations.’
      • ‘Bedrock structures tend to be more regional in spatial outline compared with glacial lineations and in satellite images are often characterized by a rough and irregular surface texture.’

    3. 1.3 The division of text into lines.
      ‘the punctuation and lineation are reproduced accurately’
      • ‘Lederer's lineation usually coincides with units of sense and syntax - punctuation occurs more often at the end of a line than within it.’
      • ‘Belabored, bejeweled-interestingly, the poem seems closer to the surface flash of many contemporary poems than the severe lineations and stark vivid colors of Plath's late work.’
      • ‘All drafts and variants are listed except for minor revisions of lineation and punctuation.’
      • ‘Holmes' own manipulation of language allows the reader to enter into his private universe, offsetting tight lineation and formal structure with inventive wordplay.’
