• Resumen

  • The understanding of turbidite systems has improved during the last decade mostly due to the improvements on 3D seismic and 3D visualization. In this scenery, outcrop analogue studies have been once more regarded as an indispensable tool since they cover scales of observation which are non reachable yet by conventional subsurface techniques and have significant predictive and reservoir implications, and also due to the fact that outcrops continue supplying with valuable depositional models. It is in this context that the Geodynamics and Basin Analysis Group (GGAC) at Universität de Barcelona has developed studies leading to the 3D digital characterisation of the geometry and architecture of several turbidite systems in the Aínsa basin. We illustrate the methods and results obtained for one of these turbidite systems. The modelling followed a hierarchical approach and covers scales ranging from the entire turbidite system (1 OO's of metres) to single bed (centimetres). Results evidence different effects of tectonics on internal architecture and allow a discussion on the applicability of the available modelling algorithms.
