The outstanding motivations that anticipated debates on the extension of these Ishiagu mineralized fractures as gotten from previous researches and already developed mines are attributed to the facts that: 1) There is a close relationship between the Pb-Zn mineralization and the structural features in Ishiagu; 2) The fractures normally fade out ...
This study assessed the concentrations of potentially harmful elements (Cu, Pb, Zn, Mo, Ni, Co, Cd, Cr, Mn and As) in agricultural soils and plants (tubers, fruity and leafy vegetables) and their ...
The AmalHE Pb-Zn deposits at Ishiagu in the Imo State of gamated Tin Mines of Nigeria Ltd. drilled several holes Nigeria are located in the southwestern tip of the in the area between 1949 and 1952 to determine ore Abakaliki anticlinorium (Fig. …
In mining communities such as Ishiagu, Nigeria, mining activity by both commercial and local miners is one of the primary causes of lead and cadmium contamination. …
so important, but cannot be overemphasized. Fracture is the key geological model for Pb-Zn mineralization, and thus the major source of Pb-Zn ore in Ishiagu, Ebonyi state, Nigeria. There is therefore the need for a suitable geophysical method of exploration for easy extension of the known zones of mineralized fractures in Ishiagu, so
This research assesses the distribution of Pb, Zn, Cu, Cd, Co and Ni in soils in Ishiagu. Mining has become prominent in this area because of existence of Pb – Zn lodes, veins and veinlets. It has thus become necessary to assess these because these metals are associated with Pb-Zn mineralization and
Pb in soil at various distance and depths was assessed at Pb and Zn mining site in Ishiagu Ebonyi State, Nigeria to determine the furthest distance travelled so far and the concentration at the ...
1. Introduction. Mining is a huge economic resource at Ihetutu, Ishiagu, Nigeria. The Ihetutu Pb-Zn mine in Ishiagu is the oldest, amongst the several mines dotting the area.Despite the huge benefits accruing from the mining business to the government, individuals, and corporate bodies engaged in it, its activities constitute the most important source of heavy metals in the …
Lead-zinc (Pb-Zn) sulphide mining activities in the Ishiagu area in the lower Benue Trough, southeastern Nigeria have a potential significant impact on the quality of soil and water resources and, by extension, animal health and agricultural produce within the environment. Mining activities date back to the 1960s (NGSA, 2010).

This study investigated the concentrations of cadmium (Cd), lead (Pb) and zinc (Zn) in soil and vegetables, and the associated health risk of ingesting vegetables from Amaonye-Ishiagu farming zone ...
The effects of mine water from Pb and Zn mines on agricultural soil in Ishiagu, Ebonyi State, Nigeria was investigated using standard analytical methods. The soil was observed to be acidic with loss of SO4 PO4 NO3 and total organic matter (TOM) with soil impaction.
This study summarizes findings of researches in active/abandoned lead–zinc mines in Enyigba and Ishiagu mining districts including social surveys in the localities surrounding the mines in order to …
this study, eight (8) homogenous soil samples were collected from mining sites in Enyigba, Ameri and Ishiagu in Ebonyi State, south-eastern Nigeria and analyzed for Pb, Zn, Ni, Co, Mn, and Ag. Metal concentration was determined using the Atomic Absorption Spectrometry (AAS) technique. Result for the heavy metals followed the
Ishiagu area of Abakaliki Basin, Nigeria to delineate the Pb-Zn mineralization in the sedimentary bedrock. Recorded as VLF-EM anomalies are the in-phase and quadrature components of the geomagnetic transfer function, tipper due to induction and these reflect the conductivity contrast between the Pb-Zn mineralized veins and the host rock.
The predominant pollutants of agricultural soils around Pb Zn mines around the globe, especially in China were found to be Pb, Cd and Zn ... fruits (Cucumis sativus) and …
The Pb-Zn deposits in Ishiagu area appear to be the southern limit of mineralization in the Benue Trough and the Pb-Zn mineralized zone extends over a distance of 500 km in a narrow belt from Ishiagu in the lower Benue Trough to Zurak in the upper Benue Trough, likewise the extent of igneous intrusions in the Benue Trough. ... also calls for ...

Ishiagu Pb/Zn mine is located between latitude 60 05"N and longitude 70 35" E in the South-eastern end of Nigeria (Figure 1). The mine site is an extension of the huge Pb/Zn ore deposit from Ishiagu through Benue up to Zurak in the North (Nehikhare, 1987).
CONCLUSION The total concentration of all the mobile heavy metals in soil revealed that mining activities in the Pb-Zn mineralization regions of Ameri, Enyigba and Ishiagu in Ebonyi State, South-East Nigeria, were above the normal soil composition based on Bowen (1979), and in the order Mn> Zn>Pb>Ni>Ag>Co.
To extend mining activities in Ishiagu, a better understanding and reconsideration of the continuation of exposed ores is necessary. Having confirmed the local mining in the area to be ... As Ishiagu Pb-Zn deposits represent an integral part of Benue Trough sedimentary basin evolution, strategies for exploring them must take into account the ...
