Detailed geophysical investigation was conducted in the east central part of Wadi Araba area utilizing Horizontal-Loop Electromagnetic (HLEM), magnetic, gravity and induced polarization to investigate the subsurface geological features and the possible mineralization zones. The results of potential field methods outline intense positive and negative anomalies trending NW-SE. This feature is eighter a dyke, or a fault-bounded block of different rock types. The electromagnetic survey reveals significantly altered zones (conductive bodies) trending NNW-SSE and NW directions. The Induced Polarization surveys were presented in pseudo-sections representing the apparent resistively and metal factors. The alteration zone probably indicates presence of mineralization along the NNW-SSE contact between the basement complex (Precambrian) and the overlying younger sedimentary rocks. |

The Dead Sea rift represents the northern part of the African Arabian rift system. A sinistral strike-slip motion along the Dead Sea rift is confirmed by the continuity in the restored trend of the structural elements. Numerous researchers discussed the structural and lithological evidence for that movement before. Hatcher et al. (1981) first discussed the geophysical evidences. In this study new evidence based on uranium mineralization along with a detailed gravity survey, carried out in the last decade in Dana and Timna areas is used to emphasize the strike-slip movement. |

A geoelectrical survey utilizing a Schlumberger array has been made at the Kaffrein dam site, northeast of the Dead Sea, Jordan, in order to investigate the subsurface channel seepage areas and to evaluate the hydrological conditions of the dam. Ten vertical electrical soundings (VES) were conducted in October 2002 utilizing the Campus GeoPulse Resistivity Meter. The VES were taken with a maximum spacing of 500 m. Geoelectrical sounding data were interpreted by partial curve matching technique to obtain the initial 1D model parameters. This initial model was then used to obtain the final layer parameters through inversion technique. The best-fitting lower bound (minimum) and upper bound (maximum) models were derived under 1 to 2% error level. The VES indicate the presence of a conductive layer (7.7-109.7 Ωm) inside the alluvial deposits, which may be ascribed to the presence of circulating water beneath the axis of the dam. The precipitation of iron oxides and magnesium minerals on dolines, as well as the monitoring of seepage on shallow boreholes downstream have confirmed the electrical resistivity results |
