2D and 3D Modeling of the Stratigraphic Sequences at the Adriatic and Rhone Continental Margins
Abstract
LONG-TERM GOALS. My goal within the EuroSTRATAFORM program is to understand the creation of the preserved stratigraphic record on continental shelves and slopes as the product of physical processes acting with spatial and temporal heterogeneities. I have been using numerical models to provide insight into the formation and preservation of stratigraphic sequences at margins. My goal has been to obtain a quantitative understanding of the interactions of environmental parameters and their influence on stratal architecture and facies distribution. I wish to be able decipher the stratigraphy on margins to read the geologic record of the past and predict future stratigraphy. OBJECTIVES. EuroSTRATAFORM represents an opportunity to extend the STRATAFORM approach to test model applicability at new margins and to expand the capabilities of our products. The Rh ne and Adriatic margins are similar to the earlier field areas in that they are mid-latitude clastic margins, but the stratigraphy is much more affected by the 3D geometry of the basins. The forcing provided by these boundary conditions provide a challenge, but are also necessary for modeling realistic systems. My aim is to quantitatively determine the system response of margins to different forcing functions sufficiently to be able to both predict stratigraphy and invert observed sequence architecture for geologic history. APPROACH. I have used numerical models as a tool to provide insight into the formation and preservation of stratigraphic sequences at continental margins. To study these margins I will apply a multi-pronged approach. 1) Together with Italian and French colleagues, I will modify and apply our existing 2D stratigraphic models to serial sections of the two EuroSTRATAFORM margins. This will test the portability of the models.
