The latter form without total removal of polymer from beneath the graben system. The delta-toe fold-thrust belts are formed by polymer bulges and fault-related detachment folds that have thickening of the ductile polymer in their cores. Multiload wedge models show the formation of younger delta-top extensional graben systems above older fold-thrust belts. The analog model results show structures similar to those found in many delta systems and provide kinematic models for their evolution. This content is PDF only.
