|Abstract:||A very important alluvial fan clastic sedimentation, took place in the NNESSW trending Valles-Penedes graben (northeastem Spain) during Miocene time. Shallow lacustrine and paludine areas developed in distal zones of these alluvial fan complexes during Burdigalian (Early Miocene). At that time both facies development and their distribution were closely controlled by tectonic activity. Fault scarp retreat and back-faulting processes in the southeastem edge of the basin (observed in westem Valles afea), originated an expansive advance of distal alluvial-fan facies in that direction. The decreasing or cessation of the activity of the southeastern margin fault ca~sedi,n Late Burdigalian time (while faults in the northwestern margin were still active) facies redistribution, and gave way to the assymetry of the basin. Finally lacustrine, marine and transitional deposits of late burdigalian and langhian age, were laid down overlapping the southeastem inactive margins.|
