Structural map of the base of the Fontainebleau Sand Formation. The map was constructed by digitizing outcrops (red points) or using well data (black crosses). Altitudes of the base of the formation were then extrapolated to reconstruct the whole surface. Altitude of the surface is given in meters above mean sea level. Black lines highlight axes of main undulations. See text for discussion.
