Sedimentation model of piggyback basins: Cenozoic examples of San Juan Precordillera, Argentina

Piggyback basins are one of the most important sediment storage systems for foredeep basins within foreland basin systems, so understanding the dynamics of sediment accumulation and allocyclic changes is essential. Three alluvial systems are proposed here to depict sediment movement along the piggyb...
