Structure et cinématique des peridotites feldspathiques du Cap Bougaroun (Algérie)

The Bougaroun Cape ultramafic body (Algeria) is located in the internal zone of the Maghrebine range. This body is similar to the ultramafic bodies of the Betico-Rifan range. Peridotites are associated with kinzigites. Observed structures and deformations correspond to a horizontal asthenospheric flow direction along a vertical plane. This could have been produced in the asthenosphere below a north-south rift or an incipient ocean spreading centre. The opening age is uncertain, hercynian or alpine.
