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.
in fold. ...simpler types of folds the axis is horizontal or gently inclined, it may be steeply inclined or even vertical. The angle of inclination of the axis, as measured from the horizontal, is called the plunge. The portions of the fold between adjacent axes form the flanks, limbs, or slopes of a fold.
