“…Any discontinuity observed in the smoothened curve was attributed to vertical variation of electrical resistivity with depth. The smoothened curves were quantitatively interpreted in terms of true resistivity and thickness by a conventional manual curve matching procedure using master curves and auxiliary charts (Orellana & Moony, 1966;Akpan et al, 2013).…”

“…The occurrence of groundwater in the CBP is facilitated by the presence of secondary structures like fracture, faults, joints, fissures and other weathered litho-units. Ground water yield from these structures can occur even at depths as low as 50m and may be poor in yield in some locations (Edet et al, 2011;Akpan et al, 2013). The single largest hydrogeological province is the CRPP, it covers the northern, central, southwestern and Northwestern parts of the study area.…”

“…The permeable sandstone appear to be an eastward extension of the adjoining Afikpo sandstones (Petters, 1989;Odoh, 2010). Most of the litho-units are porous and thus will have high yielding aquifers (Akpan, 2013).…”

“…Higher electrical resistivity values were observed in location where poorly cemented high grain size materials like gravels pebbles, coarse sands, breccias and other detrital materials dominate the litho-strata. Materials with low electrical resistivity values are prevalent in locations where surface outcrops of clayey and argillaceous materials were observed (Akpan et al, 2013). The top soil across the profile consists of decomposed organic materials and lateritic materials with silty clay intercalations.…”

“…These observeations show good correlation with lithology logs from nearby boreholes where sandy materials dominate the subsurface composition in this layer. The sands are usually saturated with water and form the dominant layer where groundwater is usually extracted from (Edet et al, 2011;Akpan et al, 2013).…”

Aquifer positions were determined by using Schlumberger electrode configuration to conduct Vertical Electrical Soundings in 67 communities within the study area. This study was carried out because of the presence of failed boreholes and manually dug wells in some of the Local Government Areas in the study area. More précis information relating to the exact location of aquifers is therefore needed for successful management of water resources in the area, in the face of dwindling availability of portable water, occasioned by failed boreholes and the need to carter for the increasing population of inhabitants of the area. Interpretation of data showed two to six geoelectric layers. Reflection coefficient and resistivity contrast values greater than 0.9 and 19 respectively, were obtained in some VES stations. Productive shallow and deep aquifer terrains were identified with depth of 60 m and 150 m respectively and resistivity range of 100.0-500.0 Ωm for shallow aquifers and 1000-2500 Ωm for deep aquifers, respectively. The lithologic materials for the aquifers were sand/sandstone and very coarsed grained sand/fractured basement, respectively. The above inference on lithology was constrained by borehole logs in the study area.

Application of electrical resistivity to assess subsurface geological and hydrological conditions at post‐tin mining sites in Indonesia

et al. 2020

View full text Add to dashboard Cite

In many parts of Southeast Asia, opencast hydraulic tin mining has been carried out since the colonial era. Regardless of its scale, this mining method has significantly affected microtopography and left extremely degraded soil surfaces, where vegetation can hardly grow. Therefore, the identification of a feasible method for the rehabilitation and reforesting of these areas is a long‐term issue. In this study, we aimed to clarify the subsurface geological (soil properties and distribution) and hydrological conditions at a post‐tin mining site on an Indonesian island using an electrical resistivity survey combined with microtopographic information. The electrical resistivity survey of the study site provided information about the distribution of bedrock and sandy and clayey soils, reflecting mining activities. Furthermore, direct and continuous groundwater level monitoring showed the ranges of groundwater fluctuation depending on the soil and climate conditions. Our study demonstrates that subsurface assessment by electrical resistivity survey can provide essential information, contributing to the development of feasible plans for reforestation or transformation to agricultural land at post‐tin mining sites through the improvement of physical conditions and soil fertility.
