Currículo Resumido

Filipe Medeiros Rosas frosas@fc.ul.pt

Assistant Professor with Habilitation (Department of Geology)

My research is mainly focused on using analogue and numerical geodynamic modelling techniques applied to the resolution of different tectonic problems at different scales.

I have recently been testing prevailing interpretative conjectures of the tectonic evolution of different segments of the Eurasia-Africa (Nubia) plate boundary (offshore SW Iberia and NW Morocco).

Recent carried out geodynamic models include: morpho rheological obstacles across strike-slip systems and related morpho-tectonic patterns; different crust rheological control on delocalised vs. narrow rift-related structures; active vs. passive strain accommodation above thrust ramps systems of different geometries; fault interference and associated stress transfer between active thrust and strike-slip faults.

One of my main research topics of interest is the Alpine (late-Miocene) tectonic reactivation of the South and Southwest Iberian margin, and specifically the use of geodynamic modelling to test the possibility of induced subduction initiation along this (still) passive margin (in which seismogenic /tsunamigenic source of the 1755 Great Lisbon Earthquake is thought to be located).

As a professor at University of Lisbon (Faculty of Science, Geology Department) I am presently responsible for the Tectonophysics course (MSc in Geophysical Sciences) and for the Experimental and Numerical Modelling of Geological Processes course (MSc in Geology – Structural Geology). I also teach the practical courses of Structural Geology (Geology degree) and Computational Methods in Geology (Geology degree).

I am also a Tutor (off-campus) of Heriot-Watt University - ISPG, where I teach the Petroleum Geoscience course in the MSc degree of Petroleum Engineering


Scientific Interests

My research is mainly focused on using analogue and numerical geodynamic modelling techniques applied to the resolution of different tectonic problems at different scales. I have worked on the tectonic characterization/interpretation of the SW Iberian Variscan orogen, during which I have carried out geological mapping of high-grade gneiss terranes and analogue modelling of sheath folds formed under non-coaxial shear regimes. I also tested prevailing interpretative conjectures of the Present-day tectonic evolution of different segments of the Eurasia-Africa (Nubia) plate boundary (offshore SW Iberia and NW Morocco). One focus of my research is the Alpine to Present-day tectonic reactivation of the South and Southwest Iberian margin, and specifically the use of geodynamic modelling to test the possibility of induced subduction initiation along this (still) passive margin (in which the seismogenic/tsunamigenic source of the 1755 Great Lisbon Earthquake is thought to be located). The scope of my geodynamic modelling work encompasses thrust, rift and wrench tectonics systems, including namely the following published topics: a. Analogue modelling: 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 systems with different geometries; Modelling of fault interference and associated stress transfer between active thrust and strike-slip faults. b. Numerical modelling: 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.
