Footwall progradation in syn-rift carbonate platform-slope systems (Early Jurassic, Northern Apennines, Italy)

► We document short-term synrift (Early Jurassic) carbonate platform progradation. ► Prograding clinoforms made use of accommodation space produced by extensional fault. ► The slope was a Lithocodium- and other microproblematica‐dominated carbonate factory. ► Progradation was aborted due to hangingwall subsidence outpacing sedimentation rates. ► The downfaulted former slope is overlain by a turbidite-dominated bypass wedge.
