TECTONIC EVOLUTION
Of the Golf of Mexico
Laurasia
- Pangea fragmentation (Upper Paleozoic-Lower Mesozoic).
- Continental shale deposits during the Mesozoic.
- Marine water invasion.
- High evaporation.
- High volumes of salt deposits during the Jurassic forming evaporites.
- Carbonate sedimentation during from Late Jurassic to Late Cretaceous.
Gondwana
From Naugen and Mann (2015).
TECTONIC EVOLUTION
From Trudgill et al. (1999).
- Thermal subsidence during the Cretaceous.
- Uplift of the Sierra Madre Oriental (Laramide Orogeny).
- Clastic sedimentation from Paleogene filling the basin (hemipelagic and turbiditie systems).
- Tectonic inversion
- Foldbelt devolpment.
TECTONIC EVOLUTION
