WebIsoclinal folds that have been overturned to the extent that their limbs are nearly horizontal are called recumbent folds. Folds can be of any size, and it’s very common to have smaller folds within larger folds . Large folds can have wavelengths of tens of kilometres, and very small ones might be visible only under a microscope.

WebA fold is an undulating structure (wave-like) that forms when rocks or a part of the earth’s crust is folded (deformed by bending) under compressional stress. The folds are made up of multiple strata (rock layers). The folds that are upwardly convex are called as anticlines.
