Abstract

Gravity survey was undertaken in Zaria and its environs in the Basement Complex of northern Nigeria to locate sub-surface geological structures in relation to mineral prospect of the study area. Measurements were obtained with the use of Lacoste and Romberg gravity meter. The data obtained were subjected to analysis. The results revealed three anticlines and four synclines as geological subsurface structures in the study area. These are concentrated between Gangara, Tandama and Danjo areas. The structures are of interest for detail and further follow-up mineral exploration. Depth estimation by half width technique was used to obtain depth to the bodies responsible for the gravity anomalies. The causative bodies are depicted in two-dimensional models (2D) and found to be deeply deposited.
