Significance of Upper Triassic to Lower Jurassic salt in the identification of palaeo-seaways in the North Atlantic

This work uses high-quality reprocessed 2D data, tied to borehole information, address the development of North Atlantic Jurassic seaways on continental margin West Iberia. The seismic data reveal full thickness Mesozoic syn-rift strata filling deep-offshore basins in this latter region. Tectonic subsidence resulted separation seaway into distal and proximal sectors. As a result, backstripped curves for Iberia document important tectonic during Late Triassic-earliest Jurassic. Lusitanian Peniche were part same early stages rifting, with rift-shoulder exhumation occurring between from onwards. We estimate 5 km Basin Triassic-Early when compared ~1.1 recorded Basin. Critically, stratigraphy shows that Iberia, Newfoundland, Sea show tripartite depositional evolution stacked continental, evaporitic, marine strata. similar Early Triassic-Jurassic stratigraphic records suggest co-genetic other along margin.
