Title | : | Integration of Aeromagntic Data and Landsat Imagery for structural Analysis for discovery of Kimberlites in parts of Eastern Dharwar Craton |
Country | : | India |
Authors | : | G. Ramadass || A. Subhash Babu || M. Preeti |
Abstract: In this study, different digital format data sources including aeromagnetic and remotely sensed (Landsat 8 and ASTER) images were used for structural and tectonic interpretation of the Mahabubnager and Gulbarga districts of Telangana and Karnataka states in the Eastern Dharwarcraton. From analysis of Landsat and ASTER images, the surface morphology and major lineaments trending in the NW–SE, E-W and NE-SW were identified. Qualitative analysis of IGRF corrected aeromagnetic data were carried out using the analytical signal, reduction to pole, horizontal & vertical gradient maps, several lineaments trending in three major directions NE-SW, NW-SE and E-W were delineated.

Title | : | Effect of Sericitization on the Engineering Properties of the Miango Granite Porphry, North Central Nigeria |
Country | : | Nigeria |
Authors | : | Daku S.S. || Bala D.A. || Adamu M.S. |
Abstract: The effects of sericitizaition on the engineering properties of the Miango Granite porphyry located in Bassa Local Government Area (L.G.A), Plateau State, Nigeria was carried out. The tests carried out on the twenty rock samples include; aggregate crushing and impact tests, water absorption, durability tests, specific gravity and petrographic examination. An average aggregate crushing value of >20% for most of the rock samples show that the rocks are relatively weak while other tests such as aggregate impact values of 18%-23%, water absorption of <1%, durability test (soundness values) of <12% and specific gravity values are fairly good.

Title | : | Analysis of Microstructural Properties of Paleozoic Aquifer in the Benin Formation, Using Grain Size Distribution Data From Water Borehole In Akwa Ibom State, Nigeria |
Country | : | Nigeria |
Authors | : | Udoh F.Evans || Nyakno J. George || Aniekan M. Ekanem |
Abstract: Aquifer microstructural properties were determined using grain size distribution data obtained from core samples collected during a drilled water borehole. The core samples were collected at depth between 50-152ft (21.5-65.4m), corresponding to the aquifer's location. Samples were oven dried at 800C for 2hrs. Part of the sample was used to obtain porosity for aquifer material, while the other part was analyzed mechanically for particulate size distributions.

Title | : | Evolution of the coastline of Saidia - Cap Water (Northeastern Morocco) |
Country | : | Morocco |
Authors | : | Hicham LASGAA || Taieb BOUMEAZA || Abdellkader SBAI |
Abstract: the north-eastern coast of Morocco is a fragile area and vulnerable to the coastal erosion. This is due to a deficit of sediment load caused by the construction of the dams on the Moulouya river which ensures fattening the beach on one side and the coastal tourist developments that destroy the coastal dune system on the other. The use of the geographic information systems (GIS) allows us to study the evolution of the coastline since the late fifties. This study is carried from aerial photography in a several periods, of the topographic map of Triffa to 1 / 50 000 and Spot satellite images.

Title | : | Intergrated Geophysical Studies Over Parts of Central Cross River State for the Determination of Groundwater Potential and Foundation Properties of Rocks |
Country | : | Nigeria |
Authors | : | V. I. Obianwu || A. O. Egor || A. A. Okiwelu || E. D. Ebong |
Abstract: A total of 71 Vertical Electrical Soundings were carried out using Schlumberger electrode configuration for the evaluation of groundwater potential in parts of central Cross River State, Nigeria. Interpretation of data showed three to six geoelectric layers. Productive shallow and deep aquifer zones were identified at depths of 60 m and 150 m respectively, corresponding to a resistivity range of 100-500 Ωm for shallow aquifers and 1000-2500 Ωm for deep aquifers respectively. The lithologic data of the aquifers revealed sand/sandstone and very coarsed grained sand/fractured basement, respectively. Seismic refraction survey was also carried out within the same study area for the foundation study of rocks. The studies revealed an average thickness of 4.5 m (probably sand/clay) and 10.0 m (probably gravelly sand/shale) for the first and second layers respectively.
