Abstract—The Precambrian granitoids in Tabe (Pagadna) area located within the Federal Capital Territory (FCT) Abuja, Nigeria is underlain by migmatite, banded gneisses of hornblende and biotite—rich varieties, subordinate amphibolite, Pan African granitic intrusions, and dykes of diorite, pegmatite, and hydrothermal quartz veins/ veinlets. The rocks are generally mafic to intermediate with minor felsic compositions. The aim of this research is to determine the geochemical characteristics of the rocks relative to their iron-deposit potentials and make suggestion on the origin. Field evidence and geochemical analysis of major oxides from fifteen representative samples using Inductively Coupled Plasma Emission Spectrometric method (ICPES) reveal that the granitoids are generally metagranitoids which have been subjected to high- grade regional metamorphism that reached the upper amphibolite facies based on the presence of hypersthene and plagioclase of andesine composition in some of the rocks. Anatectic melting and fractional crystallization may have resulted to the occurrence of ptygmatic folds, folded gneissose foliation, abundant quartzo-feldspathic veins, and lenses/inclusions of very dark- coloured metavolcanics on the rocks. The rocks have a magnesian, calc-alkalic and mildly peraluminous geochemical characteristics. The general characteristics is suggestive that the rocks were derived from (fractional) partial melting of an original basaltic rock from the upper mantle / lower crust which progressed to partially melt an overlying pelitic and felsic crustal rocks during the high-grade regional metamorphism of probably the Pan African orogeny. The formation of iron mineralization within the metagranitoids is considered to be a product of late magmatic and intense hydrothermal activities that prevailed during the crustal reactivation of the Pan African orogenic event.
