This work presents a facies analysis of Buanji Group based on field data. The succession is divided into two depositional sequences which are lower siliciclastic units (ranging between 600 – 750 m thickness) of the lower and middle Buanji and upper non-clastic – clastic strata (600 ± 20 m thickness) of the middle and Upper Buanji Units. Six lithofacies (conglomerate (F1), sandstone (F2), siltstone/mudstone (F3), shale...

Geology and petrography of Sabon Garin Kara and environs part of Malumfashi sheet 79 NE Nigeria
The study area is about 40 km2 that is (8 km × 5 km) which is located in Gwarzo Local Government area of Kano state part of Malumfashi sheet 79NE which lies within Longitude E07°57’19.5” and E08000’00” and Latitude N110 51’30”andN11047‘00.Major rock types identified include medium grained biotite-muscovite granite, coarse grained muscovite-biotite granites, quartz-syenite, and quartz-monzonites. Most of the crystals show...

Structure & tectonics of hong hills in hawal precambrian basement complex, North East Nigeria
The tectonics and impact of the Pan-African orogeny on the Hong Hills area of North Eastern Nigeria has been unraveled. This work basically used structural identification and tectonic inference to decipher the deformation episodes in this region. Our results show that this area was subjected to multiple episodes of deformation and there were evidence of reworking of older structures by younger ones. Foliation, folds and...

The need to source for local construction materials that are appropriate for the massive developmental projects in Ebonyi State, southeastern Nigeria, has necessitated sampling and testing of the Maastrichtian Amasiri Sandstone in the Akpoha area of the state. Petrographic analysis and aggregate tests were conducted on six samples randomly selected from the rock deposit underlying the area. The petrographic analysis...

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...

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...

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...

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...

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...
