U–Pb detrital zircon geochronology and source provenance in the Moroccan Meseta (Variscan belt): A perspective from the Rehamna massif
Original language description
Metasandstones from early Cambrian to early Carboniferous stratigraphic successions were sampled in theRehamna massif of the Western Meseta in Morocco. The early Cambrian sample shows a single Paleoproterozoicpopulation at ca. 2 Ga suggesting a local basement source. The Ordovician sample is largely dominated by aCryogenian-Ediacaran population and minor Paleoproterozoic peaks. The Devonian sample reveals age populationssimilar to North-West African Cambrian to Devonian age spectra indicating that the southern-derivedWest Gondwana source essentially pertained up to the Devonian. The two early Carboniferous samples showmore heterogeneous zircon age spectra with a marked Ediacaran peak accompanied by Paleoproterozoic andMesoproterozoic sub-peaks indicating important re-organization of the drainage systems. One sample also showspresence of Upper Devonian to early Carboniferous zircon grains, which suggests local magmatic sources associatedto the formation of intracontinental extensional basins. The comparison of detrital zircon spectra withpaleogeographic reconstructions indicate that the early Carboniferous change in detrital zircon sources can beinterpreted in the framework of the opening of the Paleotethys ocean with coeval erosion of orogenic topographieslinked to the emplacement of a Mid-Variscan Allochthon, and/or collision of an Avalonian indenter to the north.
