单词 syncline
释义

Definition of syncline in English:

syncline

nounˈsɪŋklʌɪnˈsɪnˌklaɪn
Geology
  • A trough or fold of stratified rock in which the strata slope upwards from the axis.

    Compare with anticline
    Example sentencesExamples
    • A series of transverse anticlines and synclines are observed that have axes orientated NE-SW, approximately perpendicular to the fault zone.
    • The faults have a systematic geometric relationship with folds, with anticlines in the mutual hanging walls of fault pairs and broader footwall synclines that define the shallow dish forms of the polygons.
    • Complex folding makes detailed interpretations of the geological structure difficult, but the area essentially consists of a large, tightly folded syncline that strikes about N.20 [degrees] E.
    • A series of synclines and anticlines developed within the basin at several localities but most prominently south of the Aghios Georgios fault zone.
    • At several localities a west-verging footwall syncline has developed as a consequence of westward transport on the overlying thrust sheet.

Derivatives

  • synclinal

  • adjective sɪŋˈklʌɪn(ə)lsɪnˈklaɪnl
    Geology
    • It is distinguished from adjacent terranes of similar age by its open synclinal structure, obviously fossiliferous character, the thickness of essentially conformable strata, and the predominance of volcaniclastic rocks.
      Example sentencesExamples
      • Local unconformities and deposition in the foreland basin and intra-mountain synclinal basins occurred in discrete phases.
      • In the northwestern part of the chain, the arches are neatly separated by the Almazan basin, which has a complex synclinal structure, but they merge towards the SE.
      • The tendency towards hydrostatic equilibrium would force magma updip beyond the synclinal axis, and cause the greatest thickness of magma to accumulate at the bottom of the sill.
      • Selenite mostly formed in shallow marginal settings and was redeposited into a small remnant basin with a depocentre near the present synclinal axis.

Origin

Late 19th century: from syn- 'together' + Greek klinein 'to lean', on the pattern of incline.
