The study of the neoproterozoic granitoids in the Ifni Inlier and those of the other inliers in south-westerner Anti-Atlas shows that this magmatism evolves from magnesian to ferroan type. In the Ifni inlier, these granitoids outcrop within the sedimentary and volcanogenic formations of the Ouarzazate Super- Group SGO (615 to 540 My). They belong to two distinct magmatic episodes (i) an early one composed of magnesian granitoids with alkali-calcic and metaluminous to slightly aluminous character (quartz bearing diorite, granodiorite and monzogranite) intrusive in the lower formations of the SGO, and (ii) a late episode associated to the summit of the SGO volcanites, which includes granites and sub-volcanic syenogranites of iron-bearing type and alkali-calcic to alkaline affinity. These magmatisms resulting from the partial melting of mixed material mark the end of the last Panafrican episode and would be set up in a transition from orogenic to anorogenic settings which announce the Paleozoic cycle. They would be contemporary to posterior with the exhumation of the extensive metamorphic domes of the Western Anti-Atlas.  El estudio de los granitoides neoproterozoicos de la &#226;&#128;&#156;boutonni&#232;re&#226;&#128;&#157; (complejo plutono-metam&#243;rfico profundo con geometr&#237;a subcircular) de Ifni y de los de otras &#226;&#128;&#156;boutonni&#232;res&#226;&#128;&#157; del dominio suroccidental del Anti-Atlas, demuestra que este magmatismo evoluciona desde un tipo magn&#233;sico hacia un tipo f&#233;rrico. En la &#226;&#128;&#156;boutonni&#232;re&#226;&#128;&#157; de Ifni, estos granitoides afloran en el interior de formaciones sedimentarias y volcano-sedimentarias del Supergrupo de Ouarzazate SGO (615 a 540 Ma).  Pertenecen a dos episodios magm&#225;ticos diferentes (i) un episodio precoz compuesto de granitoides magn&#233;sicos, calcoalcalinos y metaluminosos a poco aluminosos (dioritas con cuarzo, granodioritas y monzogranitos) que intruyen en las formaciones inferiores del SGO, (ii) un episodio tard&#237;o asociado con un vulcanismo terminal a techo del SGO  y que est&#225; constituido por granitos y sienogranitos subvolc&#225;nicos de tipo f&#233;rrico y afinidad calcoalcalina a alcalina. Estos magmatismos provenientes de la fusi&#243;n de materiales mixtos marcan el final del &#250;ltimo episodio panafricano y se habr&#237;an emplazado en un contexto transicional entre los estadios orog&#233;nico panafricano y anorog&#233;nico que anuncia el ciclo Paleozoico. Este emplazamiento ser&#237;a contempor&#225;neo a posterior a la exhumaci&#243;n de los domos metam&#243;rficos extensionales del Anti-Atlas occidental
