Quantification of the source-area erodibility impact on slab breakoff signal delay in sedimentary record? {Insight} from stratigraphic forward modeling

 abstract = {Geodynamic processes, like slab breakoff are suggested to affect overlying sedimentary basin architecture. In this setting, rebound and associated surface uplift following slab-breakoff are suggested to lead to a decrease in accommodation and an increase in sediment supply, following source rejuvenation due to uplift. This eventually results in basin shallowing. Although the sediment supply intensity is generally attributed to the tectonic and/or climatic effect, several recent studies emphasize the importance of the source area erodibility as an important factor that can delay tectonic and/or climatic signals. To test this hypothesis, we modify stratigraphic forward modeling software GPM (Geological Process Modeling software provided and produced by SLB) to account for topography-dependent steady flow. The simulation includes clastic deposition in a deltaic environment. Model inputs include variations in the source area erodibility, sea level variations, tectonic rates, and variable water discharge which ac-counted for variable precipitation rates. Simulations were conducted in a stepwise increase in complexity to quantify the sensitivity of catchment scale depositional rates to aforementioned variations.},
