moved toward north. During this period, the NW-SE
strike-slip faults formed (Fig.

). The better
expressed Post-Burdiganian (end of Oligocene) phase
should be noted, when NE-SW striking faults were
formed, controlling to a great extend the recent karst
evolution in the rock massif.
Analyzing the genesis of Plateau of Vaucluse on
the base of the principal forms of surface karst,
Depambour and Guedon (
2004
) discovered recently
deformed paleo-surfaces, but they have originated on
a regional scale since Post-Miocene time. All inter-
mediate surfaces (alt. 850 m) cut the Miocene
deposits (Burdigalien) of Aurel—Sault Depression.
This reveals a major phase of Post-Miocene denuda-
tion. These surfaces of karstic flattening are assumed
to be related to the vast po1jes of the sectors of Saint
Christol and Sault. Their genesis, dependent on dys-
functions of the endokarstic drainage, could be related
