Paleoenviromental Study of Exposed Siltstone, Enagi Formation, Bida

Sandstone samples from the Enagi Formation, found at the base of sections in the study area, indicate deposition in a fluvial environment. Texturally immature yet compositionally mature, they exhibit poor sorting and abundant quartz minerals. Petrographic analysis suggests a mixed origin from igneous and metamorphic sources, supported by the presence of mineral inclusions like zircon and tourmaline. Sandstones with high quartz content likely possess enhanced reservoir quality.
