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.
Fold mountains are formed when two plates move together (a compressional plate margin). This can be where two continental plates move towards each other or a continental and an oceanic plate. The movement of the two plates forces sedimentary rocks upwards into a series of folds.
