Syenitic Magmatism and Crust–Mantle Interaction during Late Pan-African Tectonism in Southwestern Nigeria

E. E. Igonor · Asian Journal of Geological Research · 2026

Syeinite intrusions within the Igarra Schist Belt of southwestern Nigeria constitute an important yet understudied component of late Pan-African magmatism in the Nigerian Basement Complex. This study integrates petrographic observations with whole-rock major, trace, and rare eart...

Geochemistry of Pan-African Granitoids, Southwest Nigeria: Evidence of Magmatic Mixing

E. E. Igonor & A. F. Abimbola · Journal of Geography, Environment and Earth Science International · 2016

This study aimed to determine the major elemental oxides in the exposed rock types of the study area, classify these rocks on this basis and establish the relationships between the various elemental constituents and hence predict the mode of origin of the rocks. The study area fa...
