摘要：

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