Sediment supply during this
period originated from the erosion of the rifting associated uplift.
The fall of the flux from 4.9 103 km3/Myr during Middle Jurassic
(T1) to 1.9 103 km3/Myr during Late Jurassic (T2) probably shows
that the major part of the rifting-associated relief was eroded
during the Middle Jurassic.
