The clastic sediment archive records the transfer of material between lithological reservoirs, mediated by surface processes. Sedimentary provenance analysis aims to reconstruct these transfers across a wide range of temporal and spatial scales, from sediment generation and routing in modern landscapes to paleogeographic reconstructions, the evolution of mountain belts, past climatic and erosional conditions, and the tectono-magmatic-metamorphic evolution of Earth through deep time.

However, the relationship between source rocks and resulting sediment is inherently complex. Weathering and erosion control the initial composition of sediment, while transport and depositional processes such as abrasion, mixing, hydraulic sorting, intermediate storage, and dissolution may further modify its composition. Disentangling these processes requires both an improved understanding of source-to-sediment relationships and increasingly sophisticated analytical and quantitative approaches.

This session brings together studies addressing both aspects of this challenge. We invite contributions investigating sediment generation, source-to-sediment relationships and deep-time reconstructions using observations from natural systems, experiments, and numerical models, as well as methodological advances in sedimentary provenance analysis. These may include petrographic and textural approaches; single-grain geochemistry, isotopic analysis, geo- and thermochronology; mineral inclusions and thermobarometry; fingerprinting and multi-proxy provenance approaches; and statistical, computational, and machine-learning methods for analysing increasingly large and complex datasets.
