Díez Fernández, Rubén ; Arenas Martín, Ricardo ; Pereira, M. Francisco ; Sánchez Martínez, Sonia ; Albert Roper, Richard ; Martín Parra, Luis-Miguel ; Rubio Pascual, Francisco-J. ; Matas, Jerónimo | Elsevier | 2016-11An integrated interpretation of the late Paleozoic structural and geochronological record of the Iberian Massif is presented and discussed under the perspective of a Gondwana-Laurussia collision giving way to the Variscan orogen. Compressional a[...]![]()
