Abstract Sediment Routing Systems (SRS) and Sediment Generation (SG) are two branches of sedimentary geology which are complementary, although their full integration remains incomplete. SRS connect all the steps of the journey of sediments from their formation to final deposition in relation to the denudation of sediment sources, the transfer of erosional products and their final deposition. SG is a branch of provenance analysis focussing on the quantification of the processes governing the production (Qs) and dispersal of sediments from known parent rocks, and the prediction of the amount and compositional-textural properties of sediments produced under given tectonic and climatic settings. The integration of the two disciplines is fundamental to tackle some of the open problems in sedimentary geology, including (i) the dynamics regulating the generation and release of sediments from upstream catchments to the floodplains, (ii) particle trajectories, (iii) residence time and mineralogical modifications in temporary storage environments (iv) sediment selective extraction and (v) the shredding of environmental signal propagation in both (vi) actualistic and deep-time SRS. I introduce all the elements which are necessary to both disciplines, with particular emphasis on quantitative provenance analysis (QPA). The SG approach is required to quantify lithological controls on Qs, and include it into the stream power law. QPA and the ‘Provenance Toolbox’ provide the compositional framework which is necessary for the characterisation of the erosional products. Both the advantages and limitations of each analytical tool are explored, and best practices for successful analytical workflows are discussed in light of a full integration into SRS research.

定量来源分析视角下的沉积物生成和沉积物路径系统:回顾、应用和未来发展

摘要 沉积物路由系统(SRS)和沉积物生成(SG)是沉积地质学的两个分支,它们是互补的,尽管它们的完全整合仍然不完整。SRS 将沉积物从形成到最终沉积的所有步骤与沉积物源的剥蚀、侵蚀产物的转移和最终沉积相关联。SG 是物源分析的一个分支,侧重于对已知母岩中沉积物的产生 (Qs) 和扩散过程进行量化,以及预测在给定构造和气候环境下产生的沉积物的数量和组成结构特性。这两个学科的整合是解决沉积地质学中一些开放问题的基础,包括 (i) 调节沉积物从上游集水区到洪泛区的产生和释放的动力学,(ii) 粒子轨迹,(iii) 在临时储存环境中的停留时间和矿物学改变 (iv) 沉积物选择性提取和 (v) 粉碎(vi)现实和深度时间SRS中的环境信号传播。我介绍了这两个学科所需的所有元素,特别强调定量来源分析 (QPA)。需要 SG 方法来量化对 Q 的岩性控制,并将其包含在河流幂律中。QPA 和“Provenance Toolbox”提供了表征侵蚀产物所必需的组成框架。探讨了每种分析工具的优点和局限性,
