ABSTRACT The study of source‐to‐sink systems relates long‐term variations in sediment flux to morphogenic evolution erosional–depositional systems. These are caused by an intricate combination autogenic and allogenic forcing mechanisms that operate on multiple time scales – from individual transport events large‐scale filling basins. In order achieve a better understanding how these influence morphological characteristics different scales, 29 submodern have been investigated. is based...

Catchments provide water and sediment to downstream sedimentary systems, these form individual source-to-sink systems. Source-to-sink systems comprise adjacent linked segments, commonly hinterland catchments, alluvial- coastal plains, the continental shelf, slope submarine fan. The dimensions of catchment how it scales segments provides insight into tectonic controls that influence morphology sedimentation patterns in a basins evolution. In ancient successions, where routing system is buried...

Abstract Extreme hydroclimates impact sediment fluxes from mountainous catchments to the oceans. Given modern global warming, a challenge is assess sensitivity of erosion in extreme climate perturbations. Here, we reconstruct paleo‐sedimentary across an abrupt Paleocene‐Eocene Thermal Maximum (PETM, ∼56 Ma), using sedimentary archives and numerical modeling. In Tremp Basin (Southern Pyrenees, Spain), our results demonstrate that depositional volumetric rates siliciclastic sediments increased...

Abstract Spatial and temporal relationships between climate, tectonics, sea level have a primary control on sediment transport, storage, deposition in onshore offshore depositional environments. Although many simplistic models tried to predict system behavior partitioning environments response changes these boundary conditions, the alluvial external forcings coupled with autogenic processes can be highly complex unpredictable.

Abstract Shelves have previously been classified according to a wide range of criteria, such as tectonic, morphological, climatic, and process-based classifications. Here, the formation shelves is discussed in context conditioning from sedimentary tectonic processes. A three-fold division proposed: shelves, combined structural–sedimentary structural shelves. With definition shelf shallow-marine surface large areal extent located around margin deeper basin (relief hundreds thousands meters),...

The Late Møre‐Trøndelag margin western orway was characterised by steep slopes (gradient ~0.3°–3°). Mudstones dominate slope succession, although a few regionally extensive, sandstone‐dominated units are developed. We focus most...

Understanding large-scale sediment distribution patterns and morphological characteristics in subsurface sedimentary systems is highly challenging generally requires regional seismic well coverage. Here, we test a method that aims to predict first-order type of transport system ancient source-to-sink based on trends observed submodern (Pliocene–Holocene) depositional environments. An example from the Paleocene Ormen Lange (More Basin, Norwegian Sea) demonstrates application method, several...

Abstract Source‐to‐sink dynamics are subjected to complex interactions between erosion, sediment transfer and deposition, particularly in an evolving tectonic climatic setting. Here we use stratigraphic forward modelling (SFM) predict the basin‐fill architecture of a multi‐source‐to‐sink system based on state‐of‐the‐art numerical approach. The processes consider key source‐to‐sink parameters such as water discharge, load grain size simulate various sedimentary transport mechanisms reflecting...
