The increasing demands on lateritic gravels in road construction presently make it necessary to quantify the available resources that can be used construction. This study aims estimate tonnage and valorize of north flank Mount Bangou (west Cameroon) Interpretation 48 vertical electrical soundings coupled with 20 pedological wells from five gravel sites was carried out determine thickness level....

Crustal structure and fluid or melt originating in the deep crust mantle are critical regional magmatic mineral systems. However, crustal processes that entrain focus fluids from a deep-source region to metallogenic belt remain relatively undisclosed. We present magnetotelluric (MT) study of eastern Qimantagh Metallogenic Belt (QMB) northern Tibetan Plateau. Data 33 MT stations two sections 7 d...

The interdependence between geoelectrical signatures at underground petroleum plumes and the structures of subsurface microbial communities was investigated. For sediments contaminated with light non-aqueous-phase liquids, anomalous high conductivity values have been observed. Vertical changes in the geoelectrical properties of the sediments were concomitant with significant changes in the micr...

of the traditional smooth inversion this information is provided as [2J The two-dimensional (2-D) magnetotelluric inverse problem an assumption that the solution, the geoelectrical model in the MT has been addressed by several authors. The most well-known case, should be represented by smooth functions. At the same time, approaches are the search for a smooth model [de Groot-Hedlin in some geol...

This work analizes the effect of inductive and capacitive coupling from the injecting circuit to the detecting circuit in resistive field surveys. Experimental results demonstrate that if a square waveform is injected into the soil and synchronous sampling is used to sample the flat zone of the detected voltage, then the interference is greatly reduced. Furthermore, square waveforms are easier ...

The need to use groundwater resources for agricultural and livestock farms is a constantly growing issue, as these condition the socio-economic development of many areas with limited climatic regimes surface water resources. Decisions on location characteristics extraction works are based hydrogeological studies, in which geophysical techniques very useful tool. In our study, Time-Domain Electr...
