Abstract: This study motivated to determine electrical resistivity parameters of Osmania University campus area which is underlain by granitiec terrain. A total 103 Vertical Electrical Soundings were conducted with maximum electrode spacing of 150m, the results reveals four subsurface geo-electrical layers, the top soil layer of variable resisitivity value between 11.2 Ωm to 599 Ωm whose maximum thickness is 0.75 m to 8.46 m. The highly weathered second layer resistivity value varing from 1.72 Ωm to 1800 Ωm, thickness is 0.12 m to 36.6m. The third fractured layer indicated by resistivity value of 16.3 to 460 Ωm 74Ωm and thickness is 4.9 m to 87.4 m.

Abstract: Abstract:The present study wascarried out to delineate the location, extension, trend and depth of subsurface structures of Alamein area. To achieve this aim, the gravity and aeromagnetic data have been subjected to different analytical techniques. The Fast Fourier Transform technique was used to separatethe residual components from the regional ones. The resulted maps showed that the area was affected mainly bytheENE, E-W, WNWand NWtectonic trends. In addition, spectral analysis technique was applied on magnetic anomalies to estimate the depth to basement surface, which varies from 3.03 in southern part to 7.24 Km in northern part.3D-Eulerdeconvloution and tilt angle derivative techniques were carried out to detect the edges of magnetic sources and to determine their depths.Correlation between them shows acoincidence between Euler solution and zero lines of tilt angle map.

| Title | : | 2D-Euler Deconvolution technique and Electrical Self-Potential analysis for subsurface structures delineation in Matuu, Machakos County, Kenya |
| Country | : | Kenya |
| Authors | : | Odero E.O. || K'Orowe M. O. || Githiri J. G. |
Abstract: In order to evaluate groundwater potential of Matuu-Kilango area faults and fractures which are groundwater conduits had to be delineated. Earlier use of geological reconnaissance report only in siting boreholes has led to recorded cases of borehole failure in Matuu. Integrated geophysical survey involving magnetics and electrical self-potential techniques was applied over a 25 square kilometre area. Qualitative interpretation involving generation of contour maps for magnetic anomaly as well as self-potentials was attempted. Euler Deconvolution solutions were obtained using a structural index of 0.5 that gave well clustered solutions and discontinuities over the anomalous zone.

| Title | : | Classification of fault systems and characteristics in Xujiaweizi depression |
| Country | : | China |
| Authors | : | Liulu || Yanchen Li || Meina Li |
Abstract: Xujiawezi depression experienced three evolution stages, which includes Huoshiling Formation, Shahezi Formation, Yingcheng Formation, during the fault depression period ,mainly developed five strike direction fault systems. Based on the fault systems directions characteristics, we can determine that the NNW trending Xuzhong-Xudong fault are the main strike-slip fault, the NNW, approximately SN, NW, NE and EW trending faults are the strike-slip associated secondary faults. The main strike slip fault styles, the relationships among associated structures are conformed to dextral shear deformation pattern.

| Title | : | Geophysical Investigations of a Pavement Failure Along Akure-Ijare Road, Southwestern Nigeria |
| Country | : | Nigeria |
| Authors | : | O.O. Falowo || O.J. Akintorinwa |
Abstract: Geophysical investigations were carried out along two failed segments of Akure-Ijare road, named locality 1 and locality 2, with the aim of establishing the cause(s) of the incessant pavement failure along the road. The geophysical investigations involved the Very Low Frequency Electromagnetic (VLF-EM) and Electrical Resistivity Methods. The VLF-EM measurements were taken at intervals of 10 m along traverses parallel to road pavements. Two techniques were adopted for the electrical resistivity method namely: the vertical electrical sounding (VES) and a combination of horizontal profiling and sounding using dipole-dipole configuration with inter stations separation (a) of 5 m and an expansion factor (n) that varies from 1 to 5. The Schlumberger configuration was used for the VES with AB/2 varying from 1 to 65 m. Nine (9) and twelve (12) VES were carried out at localities 1 and 2 respectively.

| Authors | : | Balu L. Rathod || Jagdish B. Sapkale |
Abstract:Remote sensing data and imageries have been used for the assessment and monitoring of land use
and land cover changes, so that available resources of any region may be used properly. In the coastal areas of
Maharashtra, catastrophic and human interventions are highly influencing on coastal resources. Now there is
an urgent need to use the sustainable resources by reducing the rate of degradation. The present study is an
attempt to analysis the change detection in the major aspects of land use and land cover in the Ratnagiri district
of Maharashtra. Satellite images of the years 1989, 1999 and 2009 have been obtained from Global Land Cover
Facility (GLCF) & NRSC and used for the analysis of periodic changes in LULC of Ratnagiri.
