Deformations are generally assumed to be to a post Oligocene extensional event. The Marseille-Aubagne basins are geographically and stratigraphically separated into three basins (Jarret, Prado and Aubagne) with each of them exhibiting their own sedimentary succession. However, each of the successions includes two main units: - The lower unit which includes several formations attributed to the Rupelian age. All of these sediments are strongly or slightly deformed depending on their location with respect to the main faults.
