Abstract

New petrographic and sedimentological data from the Oligocene-Miocene mauretanien flysch of the Rifian Chain and from the terrigenous deposits unconformably overlying the internal Rifian zones provide evidence of sedimentary supplies also from plutonic and high rank metamorphic sources. This provenance is supported by the occurence of well rounded plutonic and high rank metamorphic pebbles within some conglomerate lithofacies of the Beni Ider Flysch, never found so far. Petrography of these crystalline pebbles is very similar to that of the syn-late-Hercynian plutonic bodies and of the gneissic rocks widesspread in the Calabria-Peloritani Arc and, probably, the Kabylides. The AA. believes that this crystalline detritus could represent the product of dismantling of a lost continental crust segment, originally located very near to the ghomaride Domain. - (NF)
