文摘

•: A 450–650 m thick fluvial succession was analysed along a 4.5 km wide exposure.
•: A high-accommodation fluvial setting with multiple channel belts was identified.
•: A plural, equi-style fluvial system is interpreted.
•: Fluvial channels are narrow sheets of low sinuosity or braided that relocated by avulsion.
•: The temporo-spatial variability in the geometry of ∼300 fluvial channels is quantified.
