The salt domes of Bienville Parish, Louisiana, are classic examples of the shallow or piercement-type dome, and have been prominent in the geologic literature of the Gulf Coast since the discovery of Cretaceous fossils at King's Dome in 1867.
Detailed surface mapping shows the domes to be round to oval in plan, with progressively younger sediments exposed in concentric rings outward from a central depression. Rim synclines and partial rim anticlines are also evident. Deformation of Pleistocene deposits serves to date the last period of uplift on most of the domes.
Neither the ring of upturned sediments nor the adjoining anticline has been adequately explored by drilling on most of the domes, so they may still be considered as potential producers.
