A geological cross-section along the Basque Pyrenees and the Parentis Basin (Western Pyrenees)

A new geological cross- section along the North Iberian Margin shows a complete image of the Western Pyrenees and the Parentis Basin as well as the geometric differences and age constraints between both Pyrenean fronts. The South Pyrenean front, developed during Uppermost Cretaceous- Middle Miocene,...
