Chapter One: Introduction

The geology of southern Akor and its environs lies within the Oban Massif, a component of the crystalline basement of Nigeria. The Nigeria crystalline basement in turn forms a part of the African crystalline basement and covers over 50% of the total land surface of Nigeria . The rock assemblages encountered and identified consists of mainly schists, gneisses, Amphibolite, Charnockite, Marble and Quartzites and pegmatite, Quartz vein and Aplite emerging as Igneous intrusive rocks. The area mapped and studied (Akor) is predominated by intrusive rocks and these rocks are very well exposed where the topographyis slopy along streams and river channels.

Ekwueme et al (1992) proposed that charnockite rock’s occur in both the eastern and western Oban Massif. The rocks occur as large coarse-grained, rounded and, massive bodies deformed together with the bounded gneisses. Ekwueme (1992) has shown that the diorities and charnockite are similar in composition and that the former may be retrogressive product of the latter.

The occurrences of weathering and tectonic activities were observed to have greatly affected the exposed outcrop and such effects from wet season had deformed these outcrops to boulders with reference to their shapes and sizes.
