IAS 2019 - WGSG Session

Sediment generation and associated routing systems regulate the fate of sediments from source to sink. They are intimately connected, and result from the interplay of allogenic controls such as tectonics, climate and lithology which largely control denudation, sediment transport, deposition and storage. The quantitative assessment of source to sink systems requires multidisciplinary approaches, including the determination of sediment volumes and fluxes, composition and grain-size, or, in case of ancient systems, inverse reconstruction of the source area characteristics from the detrital mineralogy of basins including geo- and thermochronology approaches.

In this session, we particularly encourage contributions focussing on how external forcing controls sediment generation, and the factors governing sediment grain-size partitioning and trajectories and their distribution within a sedimentary system. We particularly encourage contributions focussing on i) numerical landscape modelling, ii) mass balance – sediment budget – erosion rates, iii) chemical weathering, iv) mechanical wear, v) transport dynamics (partitioning and sorting) and vi depositional controls on early diagenesis. We also welcome contributions highlighting technological advances and/or applications to mineralogical and compositional analyses of sediments. While regional case studies are welcome, in such contributions authors are encouraged to emphasize the broad significance of their work.
