Recurrent deformations of aeolian desert dunes in the cretaceous of the South China Block: Trigger mechanisms variability and implications for aeolian reservoirs

Deposits of aeolian dunes accumulated in Cretaceous intramontane deserts in the South China Block underwent recurrent deformation processes affecting their toesets and foreset sediments. The Mid-Cretaceous Matoushan Formation preserves examples of soft-sediment deformation deformations associated with theropod tracks in aeolian dune apron sandstones. The Late Cretaceous Tangbian Formation in the Xinjiang Basin, shows (i) seismites associated...
