A map on which the depiction of folded or faulted strata shows them restored as closely as possible to their original geographical positions prior to folding or faulting. Balanced sections are used to ensure the palinspastic reconstruction accounts for the entire volume of the materials represented and respects the lengths of lines and the thicknesses of individual layers. The term ‘palinspastic’ is derived from the Greek palin meaning ‘again’, and spastikos meaning ‘pulling’.
