Structure, Sr–Nd isotope geochemistry and zircon U–Pb geochronology of the granitoids of the Dabakala area (Côte d’Ivoire): evidence for a 2.3 Ga crustal growth event in the Palaeoproterozoic of West Africa?

Structural, mineralogical and chemical studies show that the rocks from the Dabakala area, previously reported as gneisses and migmatites, are in fact syntectonic granitoid bodies. Three chemical associations are distinguished: (i) trondhjemitic (Dabakala tonalites and granodiorites), calc-alkaline...
