Abstract: The Upper Cretaceous Bida Basin of central Nigeria is sandwiched between the Precambrian schist belts of the Northern Nigerian Massif and the West African Craton. It extends from Kontangora on its north western margin to Dekina in the southeastern margin where it merges with the Benue Trough. It lies between Longitude 40 and 70…
Abstract: A regional gravity survey of Enugu State was carried out in order to produce Bouguer anomaly, Free-air anomaly and the Elevation map of the State for mineral exploration.Acquisition of gravity data as a tool for mineral exploration is useful because gravity differences or anomaly reflect lateral density variation in rocks extending to several kilometres…
Abstract: The geotechnical mapping of Enugu and environs was carried out and relevant field tests were performed in the process.The soils in the project area are derived from four dominant geologic formations- Ajali, Awgu( Agbani Sandstone),and Mamu Formations and the Enugu Shales. Available data from field and laboratory analyses have indicated that the soils derived…
Abstract: A detailed geophysical survey was carried out at Babbantsauni and Ledi.A regional geological reconnaissance investigation was carried out by McConnell (1949) and identified that Izom Lead/Zinc is the only known considerate Lead/Zinc deposit in Nigeria outside the area covered by cretaceous rocks. The lodes appear to trend in the same direction. He also identified…

The collapse of buildings and flooding are re-occurring disasters in several Nigerian cities, including Kaduna, for many years, resulting in the loss of lives and properties. This explains the rationale for this project undertaken by the Nigerian Geological Survey Agency with the following major deliverables and objectives:Production of Geotechnical maps showing:Areas suitable and unsuitable…
A regional gravity survey of Ebonyi State was carried out in order to produce Bouguer anomaly, Free-air anomaly and the Elevation map of the State for mineral exploration.Acquisition of gravity data as a tool for mineral exploration is useful because gravity differences or anomaly reflect lateral density variation in rocks extending to several kilometres beneath…
A geophysical investigation of suspected base metal mineralization commenced at Riruwai, in Doguwa Local Government Area of Kano State. The Survey is a ground follow – up to the 1976 airborne magnetic survey with the objective of…
Groundwater is the main source of water for the people of Kaduna and its environs particularly in the rural areas. The purpose of this study is to assess the effects of waste dumps on the groundwater of Kaduna and its environs. The study area lies between…
