Navarra T1 Transfer zone in the western part of the Central Pyrenees, example of the Oroz-Betelu- Unzue fault. SouthernPyrenees, Navarra A1 Pueyo Anchuela, Óscar A1 Millán Garrido, H. A1 Pocoví Juan, Andrés A1 Gil Imaz, Andrés AB Based on structural, stratigraphic and gravimetric data, a regional scale N 020-040 E blind-fault, namedthe Oroz-Betelu- Unzue fault, extending from the western part of the Oroz-Betelu massif to the Sierra deAlaiz thrust front, is inferred. This fault would have acted as a transfer extensional structure during EarlyCretaceous times and later, during the Alpine compression, the different stratigraphic and structuralcharacteristics of the fault-blocks would have favoured the formation of major differences between thecontractional structures occurring in the blocks of the Oroz-Betelu-Unzúe fault-zone. The Alaiz thrustsheet and adjacent areas represents a good example of the structural changes related to the Tertiaryevolution of Oroz-Betelu-Unzué transfer zone YR 2007 FD 2007 LK http://hdl.handle.net/10272/8436 UL http://hdl.handle.net/10272/8436 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 1 jun 2026
