ABSTRACT
The distribution of salt in the North Louisiana salt basin, has led to theories of a large-scale lateral migration of salt in late Cretaceous and Tertiary due to the confining pressure of the prograding Gulf Coast geosyncline on the underlying Louann salt. The present-day bed configurations provide clues to the probable evolution of the salt structure, in particular during the diapiric stage. The change from a wide pillow shape to an overhang structure, together with the continued supply of salt from the rim syncline, suggest that a dominant supply of sediments transgressing from the northeast was "squeezing" the salt into the present-day salt diapir. The differential strain from Top Sligo-Hosston time to Top Lower Cretaceous time shows some deformation in the near vicinity of the salt.
