Geology and Geochemistry of Intrusion around Mayo-Kole Area within Adamawa Massif, Northeastern Nigeria
Abstract
The Intrusion in Mayo-Kole and environs belongs to the crystalline basement rocks of the
northern part of Adamawa Massif, Northeastern Nigeria. Most of the work done within the study
area was on regional scale, no detailed work has been done on the geochemistry of the area.
Previous studies have focused on engineering geology and geotechnical assessment of gully sites
in the area. The area under study consists of granite, granodiorite, diorite and gabbro. This
intrusion is characterized by high-K calc-alkaline and classified as metaluminous and
peraluminous. Field investigations along with petrographic and geochemical studies indicate that
the series of intrusion in the study area are derived from a common magma source as a result of fractional crystallization. The geodynamic setting of this intrusion is classified as pre-plate
collision setting derived from mantle fractionates, which was formed during the Pan African
thermotectonic events in the Nigerian Basement Complex. The tectonic structures in the study
area trend mostly NE – SW and subordinately NW-SE and N-S, conforming with the regional
deformational structures which occurred during the Pan African thermotectonic events in the
Nigerian basement.
