Investigating the viability of geothermal potential within Benue state, central Nigeria from radiometric and high resolution aeromagnetic data

The study focuses on both (qualitatively and quantitatively) analysis of high resolution Aeromagnetic data for the estimation of geothermal potential within the eastern part of Lower Benue Basin and correlating the results from the qualitative analysis of Radiometric concentration data of the study area. The study area covers a total area of 18,150 km2 , six aeromagnetic sheets covers the area, major towns are Markudi,...

Crustal structure of southern Benue Trough (BT), Nigeria from 3D inversion of gravity data

3D Moho interface has been computed from the airborne Bouguer anomaly over parts of lower Benue Trough using the MATLAB program 3DINVER.M. From the study, we have computed the maximum Moho depth of 27.5 km and the minimum Moho depth of 18.1 km. Interpretation of the gravity data of the southern part of the Benue Trough suggests that igneous input contributed greatly to the understanding of its concomitant deep crustal...

Geology and Genesis of Uranium Mineralization in Tarat Formation, Mining District of SOMAIR from Tim-Mersoi Basin, Northern Niger.

The study aimed at characterizing the geochemical compositions of Tarat Sandstones horst of uranium deposit in Arlit, Northern Niger. Induced Coupled Plasma - Atomic Emission Spectrometry (ICP-AES) and Induced Coupled Plasma-Mass Spectrometry (ICP-MS) analyses were used to determine the characteristics of studied sandstones. Field observations in Takriza, Taza North, Tamou open pit mines and Tamari Prospect and factor...

Litho-structural Features of the Precambrian Basement rocks of the Benin-Nigerian Shield, Northwestern Nigeria: Implications for their Probable Evolution from the Pan-African and Brasiliano Belts

We present the petrographic and structural features of the Precambrian (Neoproterozoic) Basement rocks of the Benin-Nigerian Shield that crop out in Northwestern Nigeria within Kanoma and its environs to give an insight on the evolution and deformational episodes that pervaded them. The major rock types in the area are schists and quartzites which have been intruded by granitic rocks. The origin of these rocks can be...

Risk Assessment in Open Pit Mining and Economic Uncertainty Modelling for Optimal Decision-Making using Stochastic Simulation - a Case Study of an Iron Ore Deposit

The key economic parameters to model risks and uncertainties for optimal decision-making in the planning of a mining project include commodity price, discount and monetary exchange rate. The current status of these key parameters is known but, the risk associated with their unknown values is of importance for decision making. In this research, economic variables such as, commodity price, mining costs, annual change in...

Gold and Copper Mineralization in Lower Carboniferous Um Bogma Formation, Sinai, Egypt: Geologic Setting and Recovery

Au-Cu mineralization-bearing ferruginous siltstone bed (1.5 m thick) was identified at the lower Carboniferous Middle Um Bogma Formation (20 m thick), Sinai, Egypt. It is unconformably overlying Sarabit El Khadem (Cambrian) and overlain by the base of Abu Thora sandstone. The latter is covered by lower Jurassic basaltic sill (30 m thickness).Two technological samples were collected from siltstone bed (20 kg) and analyzed...
