The role of the Bay of Biscai Mesozoic extensional estructure in the configuration of the Pyrenean orogen: Constraints from the MARCONI deep seismic reflection survey

Seismic interpretation of the MARCONI deepseismic survey enables recognition of the upper crustalstructure of the eastern part of the Bay of Biscay andthe main features of its Alpine geodynamic evolution.The new data denotes that two domains with differentPyrenean and north foreland structures exist...
