Time and space-scales of the tectonic control of a flexural intracratonic basin: the Paris Basin

The Meso-Cenozoic intracratonic flexural Paris Basin is a good tool to dete rminate the time/space-scales of the tectonic control on the sedimentary re cord. This study is based on basin-scale 2D sedimentary geometries of the differe nt orders of stratigraphic cyles and on 1D/3D accommodation space measureme nts (space available for sediments created by subsidence and/or eustatism). Tectonic controls occur at least at three different time-scales: 230 m.y. ( basin evolution), 10-40 m.y. (major stratigraphic cyles) and 1-5 m.y. (mino r stratigraphic cyles). The evolution of the flexural intracratonic Paris basin can be described as the result of a long term thermal subsidence component with superimpositio ns of short-term tectonic components, due to intraplate deformations of 10- 40 Ma and 1-5 Ma frequencies.
