WebApr 29, 2024 · INTRODUCTION: Fold is a wave like structure which is formed by bending or flexuring of any type of planes or layers in igneous, sedimentary and metamorphic rocks due to compressional force. Folds are best displayed by stratified formations. They may be inferred from various kinds of data. WebFold mechanisms Fold mechanisms include: Buckling Bending Passive (ductile) flow Flexural slip Kinking Flexural flow The end shape of a fold is may be a produced of one or more foldmechanism.
