THE GEOLOGY, GEOCHEMISTRY AND TECTONIC SETTING OF THE BASIC INTRUSIONS OF THE AMPER – DENGI AREA, NORTHCENTRAL NIGERIA

Isah Lekmang.

Abstract
Amper – Dengi area falls within Wase Sheet 191 (NE) and is bounded by Longitudes 09o46′ 20″E to 09o48′03″E and Latitudes 09o19′25″N to 09o22′15″N. The aim of the study was to describe the general geology and geochemistry of the basic intrusions of the study area. Eighteen (18) basic intrusive rocks were sampled for geochemical analysis. The Inductively Coupled Plasma Optical Emission Spectrometer (ICP – OES) was used to analyze the samples. The host rock in the study area are majorly migmatite, gneiss, garnet gneiss, sheeted gneiss, within which the basic rocks outcrop as intrusive bodies. Based on their chemical features, the basic intrusive bodies could have evolved from a tholeiitic parent magma that underwent variable degrees of fractional differentiation. They were emplaced within an intracontinental extensional (“within-plate basalts) setting.

Key words: tectonic setting, basic/mafic, calc-alkaline, tholeiite, intrusive bodies
