• Resumen

  • Klippes up to several km size in the Variscan foreland basin of NW Spain (Cantabrian Zone) are reinterpreted as megaexolistoliths derived from advancing nappes by gravity sliding. Nappe fragments relationships don't agree with the geometric rules of thrusting. In sorne places, the arrangement of these exolistoliths implies a diverticulation mechanism or unroofing processes during denudation of advancing thrust sheets. Transport direction of sliding fragments is normal to the nappe transport direction. This fact is explained as a result of lateral changes in the crust loading due to differences in nappe stacking.
