Historical Examples

  • Anticlinal, an-ti-klīn′al, adj. sloping in opposite directions.

    Chambers's Twentieth Century Dictionary (part 1 of 4: A-D)


  • Data are insufficient, however, to indicate the extent to which the anticlinal areas are really areas of maximum shearing.

  • The crest of the Ochils coincides, therefore, more or less closely, with an anticlinal arch or fold of the strata.

  • If an anticlinal arch be a weak structure, a synclinal arrangement of strata is quite the opposite.

  • Synclinal strata therefore endure, while anticlinal strata are worn more readily away.
