Cordiali saluti Irene Bollati Segreteria Generale AIGeo _______________________________________________________________
Dear Colleagues, We invite anyone with an interest in Quaternary rivers and fans to consider submitting an abstract to our dedicated session (No. 68) at INQUA2023 in Rome (14th-20th July 2023). A session summary is below and further details can be found at the conference web page (https://inquaroma2023.org/), noting the abstract deadline of 28 November 2022.
Rivers and fans: sediment and landform archives of long-term Quaternary landscape development and environmental change (session 68)
Rivers and fans are key components of Quaternary landscapes, linking uplands to offshore marine settings. The ubiquity of their sediment records and morphological expression offers considerable potential for exploring landscape development, alongside interpreting climatic-tectonic controls across longer (104-106 yrs) and deeper Quaternary time. In mountainous areas, rivers and fans occur as terraced landforms configured into staircase sequences. These record surface uplift and climate-linked denudation, informing on base-level fall linked to drainage network configuration change. Climate-related river-fan terrace sedimentation gives insight into local environment changes (tributary vs trunk rivers), sediment supply-sourcing-routing and flood discharge, with variable coupling to hillslopes and glaciated uppermost catchment regions. In downstream, lowland areas, spatially extensive river and megafan / distributive fluvial systems develop thick sediment-soil sequences, providing high resolution records across longer and deeper Quaternary time. In this session, we invite researchers studying any aspect of river / fan sediment and landform archives that informs on longer term Quaternary landscape development (i.e. Pleistocene). We welcome studies applying geochronology (luminescence / ESR / cosmogenic, etc) alongside novel and integrated applications of remote sensing, geomorphology, neotectonics, stratigraphy, sedimentology, pedology, provenance, paleohydrology and archaeology.
