Abstract

Summary

The Western Betic Cordillera in southern Spain is occupied by extensive salt canopies of Triassic salt, they twere emplaced mostly during passive-margin Cretaceous to Paleogene time but later were thrusted and deformed during the Neogene Alpine orogenesis. Integrating surface and subsurface data, mostly legacy seismic and well log data the structure and tectonic evolution of this large allochthonous salt province was defined. Many salt-tectonic structures were recognized in subsurface seismic examples but also in the field. Regardless of the complex tectonic evolution, there are areas where passive-margin pre-Alpine salt tectonic features are still preserved, like stringers, minibasins and supra-salt carapaces. Primary, secondary and tertiary Minibasins related to the passive margin and Alpine compression stages were studied and characterized to better understand the structural evolution. These are quite unique field examples of structures associated to the evolution of allochthonous salt canopies which were mostly defined based on seismic data, especially in the GOM. They represent field analogs that can be studied for future opportunities of gas or hydrogen storage.
