Other potential field classes (GBGeology)

  • The Cerro Toro Formation - evolution of the Austral-Magallanes Foreland Basin: focusing on the Cerro Toro and its stunning coarse-grained deepwater channel systems, this field trip also visits outcrops of all 4 main formations that form most of its foreland infill (Punta Barosa, Cerro Toro, Tres Pasos and Dorotea). Detailed channel evolution/architecture in an active/complex tectonic setting is the main theme of the trip. (Field trip can be tailored from 6 to 10 days depending interest).
  • The Grés d'Annot Formation - the focus of this field trip is on spatial and temporal evolution of the Grès d’Annot turbidite system at both, basin and local scale. The highlights of this trip are: the pinch-outs from ponded mini-basins (Braux and Tête du Ruch sections); mini-basin fill-and-spill (Les Scaffarels); observation of syn-tectonic sedimentation (Saint Benoît section); detailed turbidite facies interpretation (Barrême syncline); high-resolution facies changes in channelised systems (Grès du Champsaur); and rapid architectural changes/evolution (levees-terminal splays-channel fill; Grès du Champsaur).
  • Evolution of the Buntsandstein Group - analysis of all different depositional phases of the Permo-Triassic Buntsandstein Group (all subdivisions, formations, facies), from its Permian non-conformable contact with the Vatican basement (Grès d’Annweiler), through all detailed facies of fluvial-alluvial and aeolian dominance (Grès Vosgien: Trifels, Rohberg, Karstal facies; Conglomerates through to the grès à Voltzia); ending with the marine transgression of the Middle Triassic (Muschelkalk Formation). The highlight of this field trip is the detailed analysis of the different facies, their relevance in allowing permeability prediction (reservoir quality and extension), and the full comprehension of this enormous intracratonic system as geothermal-lithium reservoir.
