Popis:	Paleomagnetism and K–Ar dating of Permian, Triassic, and Cretaceous rocks from Morocco. We have sampled and studied volcanic rocks from the whole of Morocco. Permo-Carboniferous rocks give a magnetic pole situated at 36°N and 238°E (four sites, K = 23, A95 = 20°). Triassic dolerites dated on plagioclases from 205–180 Ma have a mean pole at 72°N, 218°E (34 sites, K = 17, A95 = 6°). Middle Jurassic and Lower Cretaceous basalts and dolentes from l'Atlas de Beni Mellal (ages from 170–120 Ma) have a pole at 45°N and 251°E (13 sites, K = 26, A95 = 8°).The results may be interpreted by clockwise rotation within Morocco. We compare them also with those from other continents.
