Based on comprehensive investigations of Dupouy-Camet and extensive oil geological exploration, including geophysics and deep drilling, by the Société Nationale des Pétroles d’ Aquitaine (SNPA), the author describes the main occurrences of diapiric and semidiapiric structure in the Aquitanian Basin of southern France. Included are remarks on the stratigraphy and geological history of Aquitania and a brief discussion of the structural complexities in the north Pyrenean foothills and the Aquitanian “Basin.”

The stratigraphy is summed up by means of six columnar sections. A structural sketch map of west Aquitania and the northern Pyrenees illustrates the paleogeographic relationship between the Upper...
