Contents: 

1. Recognition of sediments and sedimentary processes (lecture: 13 hours; exercise: 3 hours)

  • sediments: basic definitions and methodology, facies, physical aspects of sedimentary processes: basic definitions of hydraulics, grain transport and primary sedimentary textures and structures (grain orientation and gradation, bedding), mass transport and secondary textures and structures (exercise 1)
  • diagenesis: compaction, lithification

2. Sedimentary environments and sediment architecture (lecture: 13 hours; exercise: 9 hours)

  • facies association: Walther’s law, (sub)environment, depositional systems – continental, transitional, marine; paleoslope: paleoflow and palaeotransport (exercise 2)
  • facies succession: permanent, cyclic and stochastic processes, events, environment evolution, migration of depositional systems (exercise 3: facial maps)
  • 3-D sediment architecture: sedimentary surfaces (erosional, depositional) hierarchy of sedimentary surfaces, boundaries, sequence stratigraphy, deposition rate, cyclicity (exercise 4)

3. Sedimentary basins (lecture: 13 hours; exercise: 9 hours)

  • sedimentary basin: basic definitions and classification (boundaries, geotectonic regime – fundamental Earth’s architecture, stress and strain in lithosphere, lithosphere plates and basins, tensional regime of basin formation and evolution; tectonic controls on basin evolution, rock salt and ground water play
  •  basin architecture: 2d & 3D methods (seismic profiles, sections and tomography) (exercise 5 & 6)
  • ancient basins: basin inversion, examples of ancient basins
  • recent basin live: DEM, neotectonics, facies and structural analysis (exercise 7)
