Abstract: A seismic velocity model that better approximates the effects of the gradually increasing velocities with depth due to compaction in clastic sediments is invested in the clastic sediment in Agbada Field in the Niger Delta in Nigeria. The velocity data were computed from seismic refraction survey. The time-distance data obtained were observed to yield to the theory of linear increase of velocity with depth; hence the curves generated were hyperbolic in shape. This formed the basis of computation of the model parameters: Vo (top-interface velocity) and k (vertical velocity gradient) by solving the hyperbolic sine equation [Sinh(kt/2) = (kx/2Vo) analytically. Graphical profiles were plotted using Microsoft Xcel software. The velocity function is represented as: V = 1712.70 + 1.083z...........

Abstract: Barind area comprised of Rajshahi, Chapai Nawabganj and Naogaon Districts, is known as the driest part of Bangladesh. Although the area is bounded by Atrai in the north, Mohanada in the west and Ganges in the south, surface water irrigation has not been developed satisfactorily due to its topography and limited availability of surface water in dry season. Groundwater is the main source of irrigation as well as for domestic supply using a large number of Deep (DTW) and Shallow tubewells (STW) both by public and private initiatives. At present there are about 8,955 DTWs and 97,669 STWs (BADC, 2010) in Barind area. In recent years, decline of groundwater table is observed in some areas of the region. Lowering of groundwater table during dry months creates problems in the operation.........

Abstract: The lower Cretaceous Alam Elbueib (AEB) Formation acts as a hydrocarbon reservoir in the subsurface of the Western Desert, Egypt. The objective of this paper is to investigate changes in the depositional settings of the early Cretaceous; mainly for Alam Elbueib Formation in Jade field using lithofacies characteristics and electrofacies analysis. It is subdivided into six units (AEB-1, 2, 3, 4, 5 and 6) and is composed mainly of sandstone with shale and siltstone interbeds at base while carbonate increases at top. AEB-3 unit consists of a succession of massive fluvial sand bodies separated by marine shale incursions and is divided into six subunits (AEB-3A, 3C, 3D, 3E, 3F and 3G)..

Abstract: This work maps the depth to basement in Masu area, which is located in the Nigerian sector of Chad basin (Lat. 12° 00' - 13° 00' N and Long. 12° 30' - 14° 00' E), using source parameter imaging and spectral analysis techniques. Application of minimum curvature in gridding the total magnetic field intensity and Bouguer anomaly data was done using the Oasis Montaj 6.4.2 software. First order polynomial fitting was applied in Regional - residual separation. Both residual magnetic intensity and residual gravity maps show the existence of intrusive bodies in the eastern part of Masu. From the aeromagnetic result, the depth to basement estimated using source parameter imaging.........

Abstract: Vertical Electrical Soundings were conducted in view to proposing a suitable location for underground storage tank (UST) placement in the site of investigation in Ore, Ondo State. Eight vertical electrical soundings were conducted using the Schlumberger configuration along Traverses A,B,C,D,E and F with a view of providing geological and geophysical information on the depth and thickness of the different sub-layers for the purpose of evaluating the possibility of locating underground storage facility. The electrical resistivity data obtained where interpreted using RESIST software Version 1.0. quantitative interpretation of curves involved partial curve matching using two-layer Schlumberger master curves and the auxiliary K, Q, A and H curves The results obtained from the quantitative.........

Abstract: Chromium is an alloying metal which improves the property of steel. For this reason it is needed in the steel industries for its metallurgical and refractory properties. This research aim at evaluating the concentration of chromite mineralization within the serpentinites rock settings of Tunga-Kudaku area within Anka, North western Nigeria. A total of more than twenty (20) surface samples were collected. Thirty five (35) of subsurface samples were collected from drill core channels. The samples were used for thin-section and geochemical analysis using a standard laboratory techniques. The result of Ore microscopy shows zoning of the chromite with an inner Cr rich core with.........

Abstract: Ground-motion prediction equations (GMPEs) have been developed for application to shallow crustal earthquakes in tectonically active regions. The objective of this article is to test predictive attenuation relationships for horizontal and vertical peak velocities for small magnitude earthquakes which were recorded in Egypt by Egyptian National Seismological Network (ENSN).More than 2500 velocity records are used in this study with distances up to 150 km from 115 earthquakes recorded by (ENSN) to develop attenuation models, with Mw magnitudes ranging from 3.5 to 5.5.In this study, MATLAB code was developed to modify parameters of attenuation model by using Ambraseys and Halldorsson attenuation models. We found that for PGV, the attenuation relationships decay faster with distance for the vertical component than for the horizontal component.
