Above a threshold thickness of ∼600 m, salt was mobilized by (1) loading beneath a carbonate wedge, (2) differential loading by prograding terrigenous clastics, and (3) basin-edge tilting and erosion. Salt structures evolved from salt pillows to active diapirs with maximum gross growth rates of 400 to 530 m/m.y.; each stage lasted 10 to 30 m.y. Three generations of diapirs were successively activated in different areas by different forces. This content is PDF only. Please click on the PDF icon to access.
