The group Lithosphere Dynamics – of the Institute of Earth Sciences (ICT) brings together researchers from the University of Évora, University of Porto and University of Minho.
The dynamics of the lithosphere at different temporal and spatial scales is the main goal. Research encompasses multidisciplinary geological and geophysical studies: structural mapping combined with advanced microscope digital analysis and geochemistry; seismic, geoelectric, magnetic, gravimetric and high-precision down hole temperature measurements methods to infer the internal complex structure of oceanic and continental lithosphere. Such combination of techniques will be used mostly in 3 main approaches:
- We concentrate our efforts in the Meso-Cenozoic Portuguese continental crust and its oceanic extension (in cooperation with the Portuguese Continental Shelf Extension – EMEPC). The recent geodynamical evolution is accessed, in interplate domains (e.g. Azores complex rift, Iberia/Africa boundary), and at intraplate ones (e.g. Pangaea break up and in the alpine reworking of previous major anisotropies).
- Understand the geodynamical context of magmatic, metamorphic and deformation processes. Studies focus on the Variscan and Cadomian deformation in Portugal, and its correlation with the Spanish and Moroccan sectors, having an important connection with several mineralization episodes (focus of Georesources and Geomaterials group).
- Seismic hazard using a new methodology combining seismic source studies and ground motion modelling with a 3D velocity model covering a wide geographic area (western part of the Eu?Nu plate boundary, Africa and Ibero-Maghrebian area) and a range of topics within the field of active tectonics – the most up-to-date deformation processes that affect the Earth’s crust, resulting in earthquakes or recent deformations in the planet?s faults and folds -, and seismic risks.
- The scientific capacity in the field of the Earth interior structure led to invitations for some members to be engaged in the emerging area of Archaeological Geophysics, in which they participate in multidisciplinary teams that study archaeological sites.
The group is also deeply committed to the training of undergraduate and graduate students and to engaging these students in research experiences, being intensely involved in undergraduate, Master and PhD programs on Earth, Atmospheric and Environmental Sciences. Furthermore the group also dedicates to outreach actions for the general society, aiming at motivating young potential future students.
