dc.description.abstractIn this survey, the possibilty of using local materials in the fabrication of a stool that could be used in taking graviraeter readings at two vertically separated platforms was investigated. It was also aimed at using the stool in obtaining data to be used for the production of a vertical gradient of gravity map for Zaria area of Kaduna State, Nigeria. A LaCoste - Romberg Gravimeter (model G512) was used to obtain data for a total of 121 stations in the survey area. The results of the measurements showed that the vertical gradient of gravity in Zaria varies from 2700 to 3800E yielding a range of 1100E. A vertical gradient of gravity contour map was then produced and correlated with the existing geologic and gravity residual anomaly maps for the same area. An analysis of the correlation showed that the low closures of the vertical gradient of gravity map corresponds to the low closures of the residual anomaly map. Since these low residual closures correspond to important geologic features, then the low vertical gradient of gravity closures bear a strong relationship with the geology of the area. The correlation also showed that a few oi the residual anomaly closures were relatively displaced to the East when compared to the corresponding low vertical gradient of gravity closures.en_US
