摘要: Abstract Paleomagnetic investigations of Early Permian and Triassic magmatic rocks from Catalan Coastal Ranges provide three magnetic directions which are interpreted as primary magnetizations partly overprints. The succession is in terms a large-scale clockwise rotations, bring the whole assembly Pyrenees, Catalonia, Corsica-Sardinia Maures-Esterel massifs southeast Massif Central to west during Permian. This major movement associated with rotation northern limb Iberian orocline Latest Carboniferous (~ 305–290 Ma). Subsequently, dextral transtensional–extensional shearing operated along Aquitanian Shear Belt between northeast Variscan southwest. latest phase Late Permian-Early alkaline magmatism probably linked Neo-Tethys opening activity Western Europe.
