SSP3.5Clinoform drivers and stratigraphic products in siliciclastic and carbonate successions
|Convener: Claudio Pellegrini | Co-Conveners: Stefano Patruno , Ronald Steel , William Helland-Hansen , Christian Betzler|
This session aims at bringing together researchers interested in the genesis, drivers, dynamics and fate of land-derived clastic sediments delivered to sedimentary basins and carbonate-prone
accretionary wedges. We will focus particularly on the process sedimentology and stratigraphy of outbuilding margin clinoforms, the basinward-dipping, chronostratigraphic surfaces that constitute the dominant architecture of most shoreline-scale (i.e., vertical reliefs of 10s m) to continental margin-scale (i.e., vertical reliefs of 1000s m) slope successions. Contributions may deal with siliciclastic-fed systems or with carbonate environments and may cover subaerial and subaqueous clinothems at delta-scale, shelf-prism-scale and continental margin-scale.
A significant scientific, economic and social interest is associated with the study of geometry, genesis, development and drivers of both modern and ancient clinoforms. These elements and factors, and their complex interactions are crucial to:(1) our understanding of deltaic, reefal, shallow-water and deepwater-slope facies distributions, including the extent and architecture
of hydrocarbon-bearing reservoir intervals; (2) our ability to predict sand and mud partitioning via sequence stratigraphy, trajectory analysis and numerical modelling techniques; (3) our tracking of palaeoenvironmental, paleoceanographic, structural and geodynamic changes through the entire sedimentary prism of margins; and (4) our estimates of the fate of terrestrial organic carbon and pollutants in transit across the clinoforms.
We invite presentations from sedimentary geologists, geochemists, geomorphologists and physical/numerical modelers that contribute to further understanding of sediment dynamics and processes, both for modern and ancient clinoform settings. We particularly welcome holistic and comprehensive approaches to: (i) understanding stratigraphic responses on the clinothem to allogenic and autogenic forcing mechanisms; (ii) the prediction of basin-floor deposits as a function of clinothem dynamics and geometry; (iii) elucidating the changing sediment gravity flow processes, transformations and products across the margin clinoform; (iv) understand the fate of organic carbon and pollutant in terms of processes and timing. We also aim to breach the gap between researchers studying present-day systems and those reconstructing ancient outcrop and subsurface systems. The practical impact and the economic and social relevance of this research shall also be highlighted.
