Research topics

Our research focuses on four main themes related to sedimentary basins:

1. Tectonics, sedimentation and paleogeography

The study of the structural framework, sedimentation patterns and paleogeography of sedimentary basins as well as its relationships with basin-forming mechanisms, magmatic activity and postdepositional deformation

Keywords: geodynamic setting, sedimentary provenance, geological mapping, structural analysis, stratigraphic analysis, continental evolution, geochronology, Gondwana, magmatism.

2. Dynamic stratigraphy

The study of the architecture and evolution of sedimentary systems from beds to depositional sequences to unravel the autogenic and allogenic controls on sedimentation and its impacts on georesources.

Keywords: facies analysis, depositional dynamics, sequence stratigraphy, architectural elements

3. Deformation in sediments and sedimentary rocks

The study of processes and products of deformation in sedimentary deposits including its relationships with tectonics and sedimentation, diagenetic history and impacts on the porous system.

Keywords: brittle deformation, structural diagenesis, deformation bands, microstructures, clay smear, soft-sediment deformation.

4. Reservoir characterization and modelling

The study of the geological controls on heterogeneities and petrophysical properties of reservoir rocks through the integration of outcrop and subsurface data.

Keywords: porous system, diagenesis, tight gas, outcrop analogs, seismic attributes
