A geological fold is a bend in rock strata that deflects the surface sideways altering the amount and direction of dip. Fold analysis allows the proper characterisation of the fold.
Several methods exist for obtaining informations from folded surface in deformed rocks. These methods include;
Folds exist over a wide range of scales in nature and their sizes often need to be expressed in an appropriate manner. This method of fold analysis uses mathematical concepts of wavelength and amplitude to properly describe folds. The complexity of this system increases as the fold deviates the simple sinusoidal wave shape. Thus, each fold domain must be analysed as a separate entity having its own amplitude and wavelength.
It is an important aspect in analysing folds. It gives the degree of tightness of a folded layer and is widely applied in the industry. The Interlimb angle is measured as follows;
