Abstract

The Twin Panyam volcanoes of the Jos Plateau, north-central Nigeria, constitute one of the most prominent centers of Neogene–Quaternary alkaline volcanism within the Benue–Cameroon Volcanic Province. This study integrates petrographic, whole-rock geochemical, and mineral thermobarometric data to constrain the petrogenetic evolution and magmatic conditions of the Panyam volcanic system. Field observations and thin-section analyses reveal porphyritic to intergranular textures dominated by olivine, augite, labradorite, and Fe–Ti oxides, consistent with basaltic to trachybasaltic magma compositions. Whole-rock geochemistry classifies the lavas as alkaline basalts characterized by elevated total alkali contents (Na₂O + K₂O). Mineral-based geothermobarometric estimates yield crystallization temperatures of 800–1,000 °C and pressures of 6–9 kbar, indicating magma storage within upper-mantle to lower-crustal depths. These results suggest that the Twin Panyam volcanoes evolved through fractional crystallization of an alkaline basaltic magma derived from a mildly enriched lithospheric mantle source. Generally, the findings enhance current understanding of post-Miocene volcanic processes on the Jos Plateau and provide insights into its broader geodynamic connection with the Cameroon Volcanic Line.
