Conceptual runoff models – fiction or representation of reality?

The South Portuguese Zone (SPZ), which host world-class massive sulphide deposits, forms the southern fold-and-thrust belt of the Iberian Variscan orogeny. This project concentrates on seismic-reflection and seismic-refraction processing efforts on a subset of the IBERSEIS deep seismic-reflection data set aiming at fixing the SPZ upper crust in high resolution. An evaluation of numerous crooked-line seismic-reflection imaging schemes demonstrated that a processing sequence involving dip-moveout corrections, a common-midpoint projection, and poststack time migration of common-offset collects provided probably the most coherent pictures considering the crooked acquisition geometry. Correlation with surface-geological data allows 4 units of different reflection character to be identified: the…
