Overview

This book presents a comparative geological and geochemical assessment of granite-hosted pegmatite-quartz veins in Akpet and Betem areas in southeastern Nigeria in evaluating their potential as sources of high-purity quartz (HPQ). Mineralogical, geochemical and statistical analyses were used to determine the genesis, impurity levels, and economic viability of quartz in the region revealing distinct genetic environments for the sites: Akpet quartz veins are associated with orogenic processes, formed under high-pressure and moderate-temperature conditions during the Pan-African orogeny, while Betem quartz is linked to epithermal systems, formed at lower pressures and temperatures in a shallow magmatic-hydrothermal environment. Trace element geochemistry indicates significantly lower concentrations of impurities such as Al, Ti, Li, and Fe in Akpet quartz compared to Betem. These elements are critical in determining quartz suitability for high-tech industries. This book will help beginners in geochemistry and mineral exploration navigate their ways in this complex but interesting discipline.
