Free online conference on pre-vegetation river systems Vegetation appeared only around 400 million years ago and is, geologically speaking, a novelty. Understanding of the dynamic evolution of rivers and landscapes before vegetation existed is therefore integral to understanding the Earth’s full history. Rivers are particularly important because they are the sediment-transport pathways that control landscape evolution and the filling of sedimentary basins, and, rivers would have acted rather different before vegetation developed. Without vegetation, what is there to hold river banks in place? What would non-vegetated floodplains look like? Would basin fills be fundamentally different before vegetation developed? Understanding pre-vegetation rivers is also of crucial practical importance because many prevegetation river deposits are ideal reservoirs for the geological storage of CO2 (IBDP & GSCO2). Understanding the formation of these sandstone successions underpins the success of a key technology to reduce CO2 emissions world-wide. In order to develop a comprehensive understanding of the fundamental processes and research questions around pre-vegetation rivers, we are hosting a free, online mini-conference with invited speakers that cover a diverse range of scales and perspectives on pre-vegetation river deposits. 11:0011:15 11:1512:00 12:0012:15 12:1512:30 13:1513:30 13:3013:45 13:4514:00 14:0014:45 [Introduction] The global importance of understanding pre-vegetation river deposits: Geological Storage of CO2 Jim Best – University of Illinois, USA [Keynote] Rivers before the advent of land plants Darrel Long – Laurentian University, Canada Processes and products on pre-vegetation wet floodplains Phil Fralick – Lakehead University, Canada Spatial variability in the depositional architecture of pre-vegetation fluvial systems Renato Almeida – University of São Paulo, Brazil -breakMeandering rivers in modern desert basins: implications for the pre-vegetation fluvial rock record Mauricio G.M.
