Oblique collision and deformation partitioning in the SW Iberian Variscides [PDF]
Solid Earth, 2016 Different transpressional scenarios have been proposed to relate kinematics and complex deformation patterns. We apply the most suitable of them to the Variscan orogeny in SW Iberia, which is characterized by a number of successive left-lateral ...

What can seismic noise tell us about the Alpine reactivation of the Iberian Massif? An example in the Iberian Central System [PDF]
Solid Earth, 2020 The Iberian Central System, formed after the Alpine reactivation of the Variscan Iberian Massif, features maximum altitudes of 2500 m. It is surrounded by two foreland basins with contrasting elevation: the Duero Basin to the north, located at 750–800 m,

Structure and petrography of the Valle Mosso pluton, Sesia Magmatic System, Southern Alps
Journal of Maps, 2017 The Valle Mosso pluton (VMP) is a Permian granitic body intruded at intermediate to upper crustal levels in the rocks of the pre-Alpine basement of the Ivrea-Verbano Zone and Serie dei Laghi shortly after the end of Variscan orogeny.
