Os granitos Neoproterozóicos do flanco oeste do maciço de Siroua (Anti-Atlas Central) são cortados por filões de doleritos orientados N-S e E-W. Estes doleritos têm uma composição de toleritos continentais de acordo com a repartição de Cr, Ti e elementos incompatíveis; os doleritos se dividem em dois grupos químicos independente da espessura e/ou da orientação dos filões. Estes doleritos toleríticos, associados ao plutonismo subalcalino de Ida ou Iploum, são concordantes com a distensão regional que afeta o maciço de Siroia na parte norte do cráton oeste africano. ABSTRACT The Upper Proterozoic granits of western side Siroua massif (Anti-Atlas central), are transected by N-S and E-W doleritic dykes. These dykes have a feature of a continental tholeiites. According to their content in Cr, Ti and their incompatible elements ratios, they can be distributed on two chemical groups unrelated of their strike and thickness. These tholeiitic dolerites combined with the subalcalin plutonism of Ida ou Illoun are compliant with the regional distension that the Siroua massif has undergone during the upper proterozoic.
