Petrography and Heavy Mineral Studies of the Eocene Sediments in Awka and Environs, Southeastern Nigeria: Implication for Provenance

Elomba, U.F., Onuigbo, E.N., Madu, F.M. & Anozie, H.C · Asian Journal of Geological Research · 2024

Petrography and heavy mineral techniques were employed in the study of the Nanka Formation in order to evaluate sediment provenance and tectonic setting. Petrographic study of the sands shows that quartz is the dominant mineral (64- 85%) with high monocrystalline to polycrystalli...
