Presentation Transcript

  1. Numerical Models of the Formation of Extensional Sedimentary Basins: Sensitivity to Rheology and Surface Processes Susanne Buiter, Ritske Huismans and Christopher Beaumont

  2. Model set-up We solve the mechanical equilibrium equations using a 2D finite-element method (sopale, Dalhousie University)

  3. Viscous-plastic rheology Strain softening Coulomb failure criterion:J2= C cos(f) + p (1-l)sin(f) Wet quartz: Gleason and Tullis, 1995 The temperature evolution is determined by solving the heat equation

  4. Extension of Continental Crust Full sedimentation, with strain softening 30 km 50 km 70 km

  5. Effects of softening and sedimentation No sedimentation With sedimentation no soft. soft. 80 km extension in all models

  6. Effect of viscous strength

  7. Effect of viscous strength - comparison GT/100 GT GT*30 All models after 70 km of extension

  8. Numerical Models of the Formation and Inversion of Extensional Sedimentary Basins Susanne Buiter, Adrian Pfiffner, Ritske Huismans

  9. Inversion PR e 60 km c 10 km c 30 km
