Geological map of the Pyrenees

Geological map of the Pyrenees

This is the first map to cover the entire Pyrenean system, thanks to close collaboration between the French and Spanish geological surveys. Underneath the geological map itself, the shading of the topographic relief produced by a digital terrain model is clearly visible. The simplified road network has been transferred to the map.

Three inserts provide a structural diagram of the entire range, a gravity map (Bouguer anomaly) and a cross-section of the lithosphere through the central Pyrenees (ECORS project), giving an idea of the convergence that led to the collision of the Iberian and European plates.

This map is based on the 1:500,000 scale model drawn up by Yves Ternet for the 1:1,000,000 scale geological map of France (1993), with supplements from Thierry Baudin (BRGM) and Bernard Laumonier (Ecole Nationale Supérieure des Mines de Nancy) for the French section, and Antonio Barnolas, Inma Gil Peña and Santiago Martin-Alfageme (IGME) for the Spanish section.
