Abstract
Recent seismic reflexion surveys (Géomanche I and II) have made it possible to draw up a new geological map of the western English Channel. The structural evolution of the basin can be better defined from the synthesis of available data. The structural pattern of the Mesozoic and Cenozoic cover results from the reactivating of ancient faults in the underlying basement: NE-SW (Caledonian), E-W (Hercynian), NW-SE (late Hercynian). The various tectonic stages which have shaped the structure of this basin are discussed; a new tectonic event has been observed between the Ypresian and the upper Lutetian.
