Mechanism of folding structural geology

Webfold, in geology, undulation or waves in the stratified rocks of Earth’s crust. Stratified rocks were originally formed from sediments that were deposited in flat horizontal sheets, but in a number of places the strata are no longer horizontal but have been warped. Sometimes the warping is so gentle that the inclination of the strata is barely perceptible, or the warping … WebAug 2, 2015 · Folds appear to have formed in response to layer-parallel shortening.
