GEOTRANSFER

Strategic Area:
Introduction:

Geotransfer is a research group recognized by the Aragon Government, that develops its work within the frame of the Earth Sciencies Departament (Faculty of Science).

Geotransfer includes 10 full-time researchers (full professors and lecturers at the University of Zaragoza) that develop their activity about basic and applied research in Earth Sciences, including regional geology, geological risks and use of natural stone in Aragón and neighbouring regions.

Implications of our research go from basin analysis to the dynamics of the Earth’s crust and emplacement of igneous bodies. The research line in applied geology deals with geological risks in Aragon and particularly the surroundings of Zaragoza, urban and infrastructure planning trough catalogues of geological hazards related to properties of soils and rocks. This research is complemented by the study of weathering of natural rocks and concrete in monuments and other buildings.

Finally, we contribute to the enhancement of geological aspects of natural heritage by means of collaboration in international programs (Geoparks) and implementation of geological itineraries and geological points of interest (PIGs).

Research Lines:

1. Tectonics, basin analysis and regional geology

Field geology, within the frame of the main structural units of the NE Iberian Peninsula (Pyrinees, Iberian Chain and surrounding Cenozoic basins). We focus on contributions to the extensional and compressional history of the Iberian plate, the application of paleomagnetism to chronostratigraphy (magnetostratigraphy), deformation of rocks (Anisotropy of Magnetic Susceptibility) and three-dimensional geometry and kinematics of structures (magnetotectonics). Analogue modeling of tectonic structures and sedimentary basins.

2. Magmatism of the Iberian Chain and the Pyrenees

Our aim in this field is to establish the tectono-magmatic evolution and crust-mantle interactions during the transition between the Variscan and Alpine cycles in the Iberian Chain and the Pyrenees. We focus on the integrated study of petrological, geochemical and tectonic data.

3. Paleoseismology, soil and rock mechanics, geophysical surveys, geological hazards

Analysis and mitigation of natural hazards of geological origin by means of thematic maps, dating and study of triggering processes and geophysical prospecting techniques. Application to active faults, karstic collapses related to undergrand cavities, landslides and rockslides.

4. Petrophysics and natural stone

Mechanical and chemical properties and applications of natural materials (stone, mortars, bricks,…). Studies for mitigation of weathering in natural materials (pathologies and durability). Study of quarries for exploration an quality control.

 

Background:

The scientific impact of the Geotransfer group can be assessed from international publications in SCI journals, many of them in the first or second quartile in Earth Sciencies categories. The activities of our group are also relevant from the social point of view, valuing the Natural Heritage in Aragon, through activities that result in production of teaching and scientific materials in the Geopark of Aliaga and Aspe-Aragon international itinerary. Besides, the research team contributes to detection and mitigation of karstic subsidence/collapse hazards in the surroundings of Zaragoza.
