“…A detailed stratigraphical description of the Chad Formation is not common literature compared to the other older formations in the basin. The sedimentology of the formation, which segregates the deposits into three members based on color and claystone/sandstone sections were described in detail by [43] . The sedimentation of the Chad Formation has been an incessant process that began in the Late Miocene to the present, whereby river and aeolian sand and clay elements are still being added.…”

“…In the Tuma well, for instance, the Chad Formation is characterized by light grey colossal claystone, minor sand particles, and some occasional pebbly horizons, and indicating some ferruginization in the deposits [43] . Eight lithofacies components were defined based on their physiognomies such as structure, facies type, grain size, boniness, sorting, color, and compaction [43] . The account of the faces components (summarized in three parts) is shown in Figure 2.…”

“…The lithofacies is also accompanied by lignite. The lower interlude has filthy claystone displaying roughening-upward sequences and sorting from clayey granite through to sandy claystone, and weakly-sorted sandstone at the uppermost [43] . Part 2 is comprised of micaceous claystone which occurred only in the interval of 70-90 meters.…”

Understanding the hydrochemical and hydrogeological physiognomies of subsurface water in a semi-arid region is important for the effective management of water resources. This paper presents a thorough review of the hydrogeology and hydrochemistry of the Hadejia-Yobe basin. The hydrochemical and hydrogeological configurations as reviewed indicated that the Chad Formation is the prolific aquifer in the basin. Boreholes piercing the Gundumi formation have a depth ranging from 20-85 meters. The hydrochemical composition of groundwater revealed water of excellent quality, as all the studied parameters were found to have concentrations within WHO and Nigeria’s standard for drinking water quality. However, further studies are required for further evaluation of water quality index, heavy metal pollution index, and irrigation water quality. Also, geochemical, and stable isotope analysis is required for understanding the provenance of salinity and hydrogeochemical controls on groundwater in the basin.

Reassessing Groundwater Potentials and Subsurface water Hydrochemistry in a Tropical Anambra Basin, Southeastern Nigeria

et al. 2020

This review presented a detailed re-assessment of the hydrogeology and hydrochemistry of the Tropical Anambra Basin. It identified and discussed the major geological formations and their groundwater potentials. The geological examination showed that the Ajali Formation is confined in places forming an artesian condition; the potentials of this aquifer decline in the western basin due to a decrease in thickness. The sandstone associates of the Nsukka Formation are aquiferous and have produced high-pressure artesian boreholes along the Oji River. The Imo Shale is characterized by permeability stability all over much of the intermediate unit. The Bende-Ameki aquifer has a lesser amount of groundwater when equated to other formations; the geologic characteristics do not produce favorable hydrogeological conditions for groundwater occurrence. The stratigraphical and structural framework suggested the presence of an efficient throughflow in the basin. Based on physical and chemical parameters of water quality, the basin holds water of acceptable quality. While there are considerable investigations on the hydrogeology and hydrochemistry, studies are short of analysis of the hydrogeochemical evolution of groundwater, water quality index, heavy metals pollution index as well as total hazard quotient. Suitability of groundwater based on agricultural water quality indices (e.g. SAR) is also salient. Therefore, future studies should address these owing to increasing dependence on groundwater.
