Characteristics, Assessment and Management of Groundwater Resources of the Coastal Aquifer in Tokar Delta, Eastern Sudan

An integrated approach of using vertical electrical sounding data, borehole data, hydrogeological, hydrochemical information and groundwater modeling has been employed in Tokar Delta to study the hydrogeological characteristics of the aquifer and to evaluate and manage its groundwater resources. A conceptual model based on the resistivity measurements is proposed which indicates the...

Groundwater Assessment of the Area between Medani & Sennar

A combination of hydrogeological investigation and a geophysical survey (vertical electrical sounding) were carried out east and the west of Blue Nile between latitudes 14º 32\\\\\\\\\\\\\\\' &13º 29’ and longitudes 33º 15\\\\\\\\\\\\\\\'&34º 00. This study area covers about 5200km2. The resistively method was employed at two locations Daim Elmashykha and...

Geoelectrical and Hydrogeological Characteristics of the Groundwater Aquifers in the Gezira Area, Central Sudan

Geoelectrical measurements in conjuction with boreholes data have been used to develop a conceptual hydrogeological model for the exploration of groundwater in the Gezira area, Sudan. This is the land between two Niles (The Blue and the White Niles), occupying an area of about 32000 km2, which is bounded by lat. 13° 30\\\\\\\' and 15° 30\\\\\\\'N. The surface geology of the Gezira area is...

Reservoir Charecterization, With Emphasis on Ghazal Formation, Upper Cretaceous, Unity Field, Muglad Basin. (South Western Sudan

The Campanian- Maastrichian continental fluvial Ghazal Formation has been investigated based on data obtained from ten (10) wells in the Unity field, Muglad Basin. Various methods have been used in the present study including different sedimentological, petrographical and petrophysical techniques using conventional cores, polarized microscope, X-ray diffraction analysis, Scanning electron...

Subsurface Structural Framework Of The Tertiary Sedimentary Rocks East Of Jeddah, Saudi Arabia

The study area lies in proximity of the Arabian coast of the Red Sea at about 45 km northeast of Jeddah city. In this study, lithostratigraphic interpretation of optimally processed Landsat TM data at reconnaissance mapping has been carried out as a precursor to geophysical interpretation, providing the basic ‘framework’ in which to view the imaged geophysical data. The Landsat-derived...

Distribution and Behaviour of Rare Earth Elements in the Auriferous Volcano-Genic Massive Sulphide Deposits and Host Rocks of the Ariab District, Red Sea Hills, Sudan

The Ariab district, Red Sea Hills region of NE Sudan comprises numerous Late Proterozoic polymetallic sulphide bodies of exhalative origin. Major minerals making the massive sulphide ore bulks show diversity in textures and accordingly, the sulphide minerals are divided in general into facies that reflect environments of deposition that differ in space and time. The sequence of ore textures...

Geological and Geotechnical Investigation on the Black Cotton Soil in Selected areas between the two Niles, Central Sudan. Geophysical investigation for Groundwater Southern Gezira (Centr

This geological and geotechnical study has been carried out to reveal the engineering performance of black cotton soil in the upper half of the land between the two Niles. The broad task is to determine geotechnical properties, mineralogical composition, origin, estimation of its potential geological hazard (swelling and shrinking) and to develope techniques by which the expansive soil can be...

Depositional Environment Geochemistry and Diagenesis of the Aptian Albian Lacusterine Abu Gabra Formation Muglad Rift Basin Sudan

The study investigates the depositional, geochemistry, and the diagenesis of the Aptain-Albian Abu Gabra Formation in the Muglad rift basin, which is one of the largest basins in the Sudan, in which the evolution and trend was controlled by tectonic activity. The Abu Gabra Formation (Aptian – Early Albian) represented the early phase of lacustrine development with thousands feet of organic...

Sedimentological Characteristics And Depositional Environments Of The Upper Cretaceous Shendi Formation, Umm Ali Area, Northern Sudan

This study investigates the paleodepostional environment, facies types, architectures and paleogeograhy of the Upper Cretaceous sediments of Shendi Formation in northern central Sudan. The methodology included surface and subsurface lithofacies analysis, petrography, grain size, heavy minerals, clay minerals and geochemical analyses. The depositional environment of Shendi Formation is...
