interpretation of the Sanaga fault zone through remote sensing (Cameroon). Its location within the big fault zones of Central Africa and of the northern boundary of the congolese CratOn. Observation of lines and curved structures on the Landast image no 199-57 has been interpreted as tectonic lineament that has been caled the c( Sanaga fault zone u. Various geological and gravimetric data provide support to this interpretation. This WSW-ENE faulted zone has had a prior dextrial movement probably during the end of the panafrican orogeny, and a later N-S shortening. In Centrafrican Republic the formerly described Bozoum-N’dele fault is drifting toward the Sanaga fault zone, thus giving rise to the (( Sanaga-N’dele fault ». The Sanaga-NiJele fault is the southern and most continuous tectonic lineament of Central Africa, and is expected to be implicated in a dextrial movement of the northern part of the Mobile Zone. with respect to the.southern part which remain linked to the Congolese Craton.
