New age constraints on the Ouarzazate Group (Morocco): implications on the hypothesis of True Polar Wander during the Ediacaran

Autor: Fernando Corfu, O. Blein, Boris Robert

The Ediacaran (635-541 Ma) is the last geological period of the Precambrian during which major changes occurred in the superficial layers of the Earth (biosphere, cryosphere, oceans, atmosphere). The paleomagnetic data from the main continents of thi

We conducted a paleomagnetic study on late Ediacaran and early Cambrian volcanic deposits and lava flows from the Ouarzazate and Taroudannt groups in the Anti-Atlas, Morocco. Four stable magnetic mean directions have been isolated using thermal demag

The 1.4 Ga Bondy gneiss complex (BGC) is one of a series of gneiss complexes that outcrops as tectonic domes structurally below Grenvillian, 1.3/1.25 Ga, marble and quartzite assemblages in the Central Metasedimentary Belt (CMB) of Quebec, western Gr
