In cylindrica l folds the crest and trough lines are parallel. to the fold axis and to each other, but in conical folds the crest and trough lines are not. parallel. Crest and trough surfaces connect the crest and trough lines on successive. horizons.
Parts of a Fold: In a series of folds it is evident like waves. They consist of alternate crests and troughs. The crest of the fold is termed as anticline while the trough is called synclines. An anticline and syncline constitute a fold. Limbs or Flanks: Limbs or a flank of the fold is sloping side from the crest to the trough.
