“…Furthermore, findings of National Nutrition and Health Survey 2014, shows that 37.8 % of household in Cross River State have access to improved drinking water sources (NBS, 2014), indicating that 62.2 % of the population are exposed to unsafe water sources. Geological, mineralogical and structural aspects of the rocks and barite occurrence have been investigated by previous authors (Ekwueme&Onyeagocha,1986;Ekweme, 1995;Adamu, 2000Adamu, , 2011Egeh, et al, 2004;Oden, 2012). Adamuet al (2014),assessed the contamination and health risk associated with abandoned barite mines in Cross River State generally, using streams and pond water.The hydrochemical assessment of pond and stream waters and trace and major element pollution of the sediments around some of the barite mineshave been investigated (Adamuet al,2013;Adamuet al, 2015).…”

The assessment of the level of heavy metal concentrations in water sources around quarries and barite mine sites in central Cross River State, Southeastern Nigeria, was carried out to evaluate the degree of contamination due to mining and quarrying activity in the area. The investigation involved the collection of twelve water samples from ponds, streams, river and boreholes around the area. The water samples were passed through 0.45 µm filter paper and preserved with a drop of 0.1M HNO3 acid. The preserved samples were analyzed for their heavy metal (Ba, Cr, Cu, Fe, Mn, Pb and Zn) content, using inductively coupled plasma-mass spectrometry (ICP-MS). The results show that the average concentration of Ba, Cu, MN, Pb and Zn were above WHO guideline value for drinking water quality, hence not suitable for drinking. The average concentration of the metals is in the order Ba>Mn>Cu>Fe>Pb>Zn>Cr. Computed values of contamination index show that the samples from four locations were contaminated. Single factor pollution index computation indicates that the waters are not contaminated with Cr, but slightly polluted with Fe and Zn, moderately polluted with Ba and severely polluted with Cu, Mn and Pb. Further, Nemerow comprehensive pollution index indicates that samples from four locations were severely contaminated. The study revealed that the water sources around the barite mines had elevated level of heavy metal concentration compared to location around the quarries. It is recommended therefore, that the water be treated before use for drinking purpose. Keywords: heavy metals, contamination index, pollution index, barite mine, quarry

“…Electrical resistivity methods have variously been used in the exploration of baryte veins by several researchers (Egeh et al, 2004;Karen, 2004;Bhattacharya et al, 2006;Oladapo and Oladapo, 2011;Luano et al, 2012;Akpan et al, 2014;Obi et al, 2014). Results of study show that high resistivity signatures were diagnostic of baryte vein structures to which baryte mineralization could be associated.…”

The use of DC electrical method in baryte mineral exploration has been investigated in Buruku northeast of Markurdi, Nigeria. The objective of the study was to investigate the suitability and potential of electrical resistivity tomography (ERT) combined with vertical electrical sounding (VES) surveys in baryte mineral exploration over known deposits. Results show that the interpreted layer resistivities correlate with the 2-D observations. The study delineated averagely 28 m deep symmetrically moundshaped resistive anomalies (1500 to 5500 Ωm) encased within low resistive sandstone formation along prospective traverses. These responses are characteristics of probable vein structures associated with baryte mineralization. Two dominant E-W and NW-SE resistivity anomaly trends were delineated. The E-W trends were more prominent and persistent than the NW-SE. They are 25 to 50 m wide and stretches to over 300 m in length. The association of mineralized veins with these trends suggests that the veins must be of early Cretaceous age. These mineralized veins correlate with locations of known baryte deposits in the prospect area which hitherto, have been exploited by artisan miners. This is an obvious indication of the utility and resolution of dc electrical method in baryte mineral exploration in the area.
