ملخص: A palaeomagnetic study was conducted at different stratigraphical positions in rocks of Upper Carboniferous age (Bashkirian) in the Illizi Basin (Algeria). Three distinct remanence directions were isolated in these rocks. The first direction is associated with a Cenozoic magnetic overprint. The second direction yields a palaeomagnetic pole (40.3[deg]S, 64.3[deg]E) that is similar to previously published African Permian poles and is interpreted as a Permian remagnetisation. The third direction gives a new Late Carboniferous (Bashkirian) African palaeomagnetic pole (28.2[deg]S, 55.5[deg]E, K = 207, A95 = 3.4[deg]). This pole is in a good agreement with previously published Saharan poles for the neighbouring periods. The combination of the new given datum with the previous Carboniferous poles of Gondwana shows that the reconstruction of Gondwana should be based on the parameters of Ricou. (1990) rather than on those of the classical du Toit (1937) model.
