Paleoesfuerzos en las cuencas de antepaís en la parte noroccidental del arco de gibraltar (mioceno superior-actualidad)

Abstract

Graphical and numerical methods of fault slip data inversion have been applied to obtain palaeostress reconstructions in Neogene and Quaternary basins, located in the northwestern part of Gibraltar Arc. The most important brittle structures affecting these sediments are high-angle faults with oblique-slip. Two sets of faults with NW-SE and NE-5W trends have been distinguished. The trend of the major axis of the palaeostress ellipse in the horizontal plane has rotated from E-W in the Upper Miocene to NW-SE in the Pliocene-Quaternary
