Mapping Potential Cassiterite Deposits of Naraguta Area, North Central, Nigeria using Geophysics and Geographic Information System (GIS).

Abstract

A Geophysical and Geographic Information System (GIS) study is presented to produce a map of potential cassiterite deposits of Naraguta area, North-central Nigeria using aeromagnetic, radiometric, geological, topographic data. Each map was analysed to extract features relevant to cassiterite mineralization and hence produce evidence maps or factor maps. Index overlay method of multiple map combination was used to integrate the resultant evidence maps to produce a cassiterite potential map for the Naraguta area. The cassiterite potential map showed that most of the area within the Jos- Bukuru Complex has high to very high cassiterite mineralization potential.
