Abstract
Palaeomagnetic study of the Beni Bousera peridotites reveals two stabl e directions of magnetization carried by magnetite associated with a f raction of hematite. A North direction with unblocking temperature oft en higher than 450 degrees C was acquired before complete cooling of t he peridotites (16 Ma). An East (D = 103.8, l = -58.6, alpha(95) = 10. 3) direction with high unblocking temperature is interpreted as the re sult of an anticlockwise rotation of 74 +/-13 degrees during Early Mio cene.
