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...

Sedimentary Facies and Depositional Environments of the Neoproterozoic sediments of the Gambaga – Nakpanduri areas of Northeastern Voltaian Basin, Ghana

The classification of the sediments into facies and the various environments in which the sediments of the northeastern Voltaian Basin were deposited has not been clearly described. Using detailed field mapping together with petrographic studies, six (6) sedimentary facies has been identified; F1 is defined by asymmetric wave formed ripple marks, F2, flute casts on micaceous sandy shales, F3 has bifurcated ripple and...

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...
