Abstract
The sedimentary record of the offshore part of continental margins is characterized by important thermic subsidence, which favours a good preservation of sedimentary sequences (contrarily to the onshore part of margins). This sedimentation in turns enhances the subsidence because of loading effects. The quantification of this total postrift subsidence (and the relative effect of both factors) is not always easy, especially when no wells are available in the area. We present here a method based on sedimentary Markers, in the Gulf of Lion.
