The role of subsidence and accommodation generation in controlling the nature of the aeolian stratigraphic record

Despite a well-documented record of preserved aeolian successions from sedimentary basins characterized by widely variable subsidence rates, the relationship between architecture and subsidence-driven accommodation generation remains poorly constrained largely unquantified. Basin as control on is examined through analysis 55 ancient case-studies categorized into settings ‘slow’ (>1–?10 m Myr ?1 ), ‘moderate’ (>10–?100 ) ‘rapid’ (>100 time-averaged rates. In rapidly subsiding basins, are thicker associated with (1) more laterally extensive dune-sets increased foreset preservation, (2) greater proportions wet-type interdunes surface stabilization features (3) interdune migration surfaces, bounding sets that climb steeply. slowly thinner, proportion sandsheets supersurfaces indicative deflation bypass. Rapid promotes steeper bedform climb, resulting in preservation original dune deposits relatively elevated water tables, leading to sequestration beneath erosional baseline encouraging development stabilizing agents; both factors promote long-term preservation. Slow results lower angles truncation forms, post-depositional reworking, where sediment exposed above for extended time-periods. Quantitative stratal relation rates basin helps constrain mechanisms which accumulated stratigraphic record.
