Abstract

Folded structures are not necessarily stable through geologic time. "Unfolding" is defined as the changes in attitude through with folded structures go subsequent to their creation by tectonic means, other than by faulting alone. The principal types of unfolding, together with their causes, are: (1) the effect of gravity on isolated structures, and the effects of loading and unloading insofar as the gravitational force is concerned; (2) basining action and its effect on unloading; (3) the action of vertical forces on folded structures; (4) migrating or "wave" folds in relation to unfolding.
