Tóm tắt

Terra Nova, 23, 241–247, 2011AbstractEarly Variscan structures and magnetic anomalies delineate four oroclines along the Variscan belt. The arcs bend the lithostratigraphic zones of the autochthon and the allochthonous terranes, which include ophiolites of the Rheic suture and units of Gondwanan derivation subducted on both sides of the Rheic Ocean. A transcurrent model dominated by right‐lateral motion explains the genesis and evolution of the oroclines and a simple plate‐tectonics scenario links late Variscan dextral strike‐slip movements in the Variscides to a broad intracontinental shear zone, kinematically equivalent to a transform fault.Terra Nova, 00, 1–7, 2011
