WebThe term fold is used in geology when one or a stack of originally flat and planar surfaces, such as sedimentary strata, are bent or curved as a result of permanent deformation. Synsedimentary folds are those due to slumping of sedimentary material before it is lithified. WebA fold is a geologic structure that is formed by layers or beds of rock being bent or folded. The plane that marks the center of the fold is called the axial plane . The line which marks where the axial plane intersects the surface … 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 … facebook öffentliche gruppe bad abbach
