Late Paleozoic strike-slip faulting in southern Europe and northern Africa: Result of a right-lateral shear zone between the Appalachians and the Urals

Stratigraphical and palaeogeographical significance of the continental sedimentary transition across the Permian–Triassic boundary in Spain

“…The general interpretation of the western Tethys in this figure is based on Ziegler and Stampfli (2001), Ziegler (1988), Stampfli and Borel (2002) and Ford and Golonka (2003). Some of the basins of Iberia were the result of reactivation of ancient Hercynian faults (Arthaud and Matte, 1977;Alvaro et aI., 1979;Ziegler, 1988;Arche and L6pez-G6mez, 1996), representing the initial phase of post-Variscan plate reorganization. This initial break-up of Pangea was related to a series of strike-slip fuults that dissected the Variscan foldbelt and its associated foreland areas.…”

Origin of the Permian-Triassic Iberian Basin, central-eastern Spain

“…This megastructure wa s origi nated during a continent-{;ontinent collision between the North Ame rica (Laurentia) Plate, Fennoscandia Plate, se veral South Europe Mic roplates and Africa Plate. Deformation took place in several phases (Late Devonian-Late Carboniferous) (Arthaud and Matte, 1977;Dewey and Burke, 19 73;Nicholls, 1974, 1984) and led to crustal shortening and thick ening, regional metamorphism and widespread gran itization (Matte, 1986).…”

“…Since the works of Arthaud and Matte (1977), it is generally accepted that the Iberian Microplate was part of a dextral megashear zone between the South ern Appalachians and the Urals, just after the Her cynian Orogenesis (Stephanian-Autunian). Using a simple Riedel di agram (Fig.…”

Triassic synthems of southern South America (southwestern Gondwana) and the Western Caucasus (the northern Neotethys), and global tracing of their boundaries

“…However, we agree with the suggestion of Gaetani et al (2005), who suggested strike-slip movements in this region. They might have been related to the activity of the major shear zone located just to the north of the Western Caucasus (Arthaud and Matte, 1977;Ruban and Yoshioka, 2005;Tawadros et al, 2006).…”
