Abstract
It would seem that the data available today leave no room for doubt that all types of folding are to be regarded as phenomena arising from the vertical oscillations of the Earth's crust. The most difficult aspect of this conception is to explain the process that leads to the transformation of vertical movements into crumpling. With a view toward clearing up this question, special structural investigations have been undertaken. The principal results may be summed up as follows Of great importance in folding is the fact that during vertical movements, the Earth's crust often splits up into separate blocks which undergo differential vertical displacement. Folding is the reaction of stratified plastic rocks to differential vertical movements of blocks. There are three types of folding to be distinguished on the kinematic basis: block-folding, folding or injection, and folding of general crumbling.
