dc.description.abstractA gravity survey was carried cut over Dutse Complex, Kano State for a total of six weeks during the months of October and November 1977, February, July and August 1978. The observed Bouguer anomaly showed that the area is characterised by negative values ranging from -350 GU to -c230 GU. The pattern of the contours on the Bouguer anomaly map suggested that the anomaly might have been due to a plug-like body, thus a computer programme for three dimensional mass modelling was used for the interpretation. It was also observed that the Dutse Complex is made up of typical rocks of the Younger granite suite such as Beiderbecke granite and theodolite with characteristic low density values. The three dimensional model studies suggest that the Beiderbecke granite is a Pluto which is 4km in thickness and about 14km in diameter buried at shallow depth of about 0.5km. The surface expression of this Pluto is a series of small cylindrical pipes of different radii which serve as outlets of the magma at depth. The rhyolite is probably the volcanic phase following the intrusion of the per alkaline granites extruded through one of the pipes within the granitic Pluto.en_US
