High-resolution imaging of the crustal-scale structure of the Central Pyrenees and role of Variscan inheritance on its geodynamic evolution.

The main objective of the IMAGYN project is to obtain a high-resolution image of the crustal structure of the Central Pyrenees through the integration of geological and geophysical data obtained from several methods.

This image is necessary to analyze the role played by Variscan structures and the petrophysical and structural heterogeneity in the geodynamic evolution of the orogen. The project has two main objectives:

(i) to deepen in areas of special interest in the Central Pyrenees by integrating new geophysical data to reduce existing uncertainties, and

(ii) to characterize the upper and lower crust of the Central Pyrenees and to extend the study area to the Ebro and Aquitaine foreland basins.

To this image of the current configuration of the orogen will be added the kinematic and flow direction characterization of the Permo-Carboniferous volcanoclastic materials of the Erill Castell-Estac basin.

The comparison with previous data from the Cadí basin will allow us to analyze the pre-Alpine configuration of these basins and to reconstruct their geodynamic evolution together with the associated granitic bodies.
