Scientific Interests

Main Interests: 

My research is mainly focused on using analogue and numerical geodynamic modelling to solve different tectonic problems at different scales. 

The scope of my geodynamic modelling work encompasses thrust, rift and wrench tectonics systems, including namely the following published topics:

a. Analogue modelling:

 
 

[Moovie above: Analogue modelling of the tectonic interference between active an strike-slip fault/shear zone and a weak (viscous) rheological obstacle. See details here.]

  • Modelling of morpho-tectonic patterns resulting from the interference between rheological obstacles and strike-slip faults systems;

  • Modelling of the control of different assumed crustal rheologies on the delocalised vs. narrow distribution of rift-related fault patterns in the upper crust;

  • Modelling of active vs. passive strain accommodation of a deformable hanging-wall above a rigid footwall in thrust ramps systemswith different geometries;

  • Modelling of fault interference and associated stress transfer between active thrust and strike-slip faults.

b. Numerical modelling:

 
 

[Movie above: Numerical modelling of polarity-reversal subduction initiation. A buoyant oceanic plateau atop the original subducting plate arrives to the subduction trench, obstructing it (resisting subduction), and triggering a new subduction zone in the opposite direction (opposite polarity). Note that the model is NOT forced externally by any imposed velocity BC, but rather is driven, exclusively, by the force equilibrium between the negative buoyancy of the subducting slab and the viscous resisting forces in the mantle. This work was led by former PhD student Jaime Almeida. See details here.]

  • Modelling (3D) of active thrust-wrench fault interference offshore SW Iberia (Gulf of Cadiz domain) and ensuing consequences in terms of seismic hazards;

  • Modelling (2D) of subduction initiation by polarity reversal;

  • Modelling (3D) of subduction initiation by polarity reversal;

  • Modelling (2D) of the main mechanical parameters governing double graben nucleation during the early stages of continental rifting.
