Item Open Access HYDRO GEOCHEMICAL PROPERTIES OF SOME SHALLOW WELLS IN KADUNA STATE, NIGERIA(Department of Geology and Mining, Nasarawa State University, Keffi, 1998-06-17) Jatau, B.S.; Umenweke, M. O.The results of measurements of pH, temperature and major-ion concentration from thirty-four shallow wells in basement complex, Kaduna State, Nigeria < are presented and discussed. The result shows that the basement area of the state has c mean temperature range of 27° C to 30° C, the pH range is 7AS to 7.17 and shows mat the water do vary slightly in temperature and also slightly alkaline. The dominant cation, calcium (Ca2 ) concentration range from 4.8 mg L to 180mg L, the (Fe2) varies from 0.5mg L to 1.25mg L while the bicarbonate concentration range from 24mg L to 102mg L. High nitrate concentration (NO3) from 108mg L to 120mg L is also observed. From the data, water from fifteen shallow wells among the studied area are polluted, while water from twenty-four others are tolerable. The sources of pollutant may be from weathering of rocks, human and animal waste and industrial wastes from superphosphate, textiles and other small scale industries in the area. If. is necessary that water from the twelve shallow wells near the industrial estate is treated before use while the- industries should be made to adopt safe waste disposal methods.Item Open Access THE USE OF ELECTRO-MAGNETIC (EM) METHOD IN GROUNDWATER PROSPECTING IN A BASEMENT AREA OF SABO, KADUNA STATE(Department of Geology and Mining, Nasarawa State University, Keffi, 1998-07-17) Jatau, B.S.Modern Technology in geophysical prospecting (Electromagnetic Method (EM) has provided instrument with better resolution, relatively high speed of operation and low manpower% requirements. Successes have greatly been achieved in water supply schemes in basement complex of this area. Use of electromagnetic method especially in groundwater prospecting in basement terrains is making process of bore-holes drilling operation successful, precise and cost effective. Electro-magnetic (EM) survey of part of the basement was carried out in the Sabo area, Kaduna, Kaduna State Basement complex terrain. An orientation survey was carried out and five profile lines earmarked and pegged at 200m spacing in between each profile line. The very low frequency VLF (Genomic EM16) method was used for the survey at a spacing (a = 20m), making a total numbers of two hundred and five VLF station points. The data from the electro-magnetic mapping were processed by graphical and contouring methods. The results from the electromagnetic responses gave an overall idea about the lateral variation in conductivity and broad lithological differentiation using the EM anomaly amplitudes in the areas where the basement rocks are not concealed is considered feasible. A closer study on the EM anomaly contour maps delineated zones of fracture (faults which are zones of interest in terms of water prospecting and even mineralization. The study examines the role performed by electromagnetic technique as a general reconnaissance geophysical survey instrument for aquifers in die sabo area in the south of Kaduna State. The results obtained are being used for further detailed investigations using other geophysical methods’ such as magnetic, vertical electrical sounding and horizontal electrical profiling.Item Open Access THE ELECTROMAGNETIC (EM) AND MAGNETIC METHODS AS GENERAL RECONNAISSANCE GEOPHYSICAL PROSPECTIVE TECHNIQUES: A CASE STUDY(Department of Geology and Mining, Nasarawa State University, Keffi, 2000-11-19) Jatau, B.S.The area of prospecting is in Kaduna South, Nigeria and is mainly a Basement Complex Terrain. Very low frequency (Geonic EM 16) and magnetic (EF 2 Fluxgate Magnetometer Scintrex) instruments are used for the reconnaissance, after an orientation survey. Based on the latter, a spacing of 20m station points are adopted for both methods. Field measurements are made using the magnetic method which is considered easier, cheaper and simpler. With this procedure the only corrections necessary are diurnal corrections. The magnetic map is generally more complex and the variations in the field more erratic and localised perhaps due to the difference between the dipole magnetic field and for the fact that magnetic field has magnitude and variable direction. The map appears to be a multitude of residual anomalies as a result of large variations in the fraction of magnetic minerals contained in the near surface rocks, thus making the precise interpretation of the magnetic field data much more difficult, however a semi-qualitative interpretation is attempted after graphical presentation and smoothing. The filed VLF measurement is relatively fast, but not as in the magnetic method. It has problems of large geologic noise component and dynamic range, which results from the relatively high transmuted frequency and the VLF-EM transmitter stations located at various places around the globe, which make interpretation difficult. However a data manipulation procedure described by Fraser (1969) and Telford et al (1976) transforms noisy non-contourable data into less noisy contourable data, hence eliminating the dynamic range problem and reducing the noise problem thereby making it easier to recognise. The two methods of geophysical prospecting serve as good means of reconnaissance and show good correlation graphically. Geological mapping through these two geophysical methods are adequate in locating and demarcating anomalies and structural features for instance faults, lineations, and other zones of structural weakness.Item Open Access GROUND WATER INVESTIGATION IN SABON-TASHA AREA OF KADUNA USING VERTICAL ELECTRICAL SOUNDING (VES) METHOD(Department of Geology and Mining, Nasarawa State University, Keffi, 2001-01-23) Jatau, B.S.; Faladun, B. S.Vertical Electrical Sounding investigation was carried out at Sabon-Tasha area, Kaduna State in the basement Complex of Northern Nigeria. Five Vertical Electrical Sounding Points (VES) were taken at various points of interest (outside cultural interferences). Abem Terremeter SAS 300C was used for the depth sounding. The Schlumberger array with a maximum length of200 meters was adopted. The interpretation was done quantitatively using the ghosh inversion filter interpretation computer program to delineate the sedimentary layers, their thicknesses and apparent resistivities. Qualitative interpretation was done and compared with existing lithologic log which showed some correlation. Generally, the result depicts basically two layers with varied potentials overlying the basement complex in the study area.Item Open Access RECONNAISSANCE HYDROGEOPHYSICAL INVESTIGATION , OF PART OF KADUNA TOWN AND ENVIRONS, KADUNA STATE, NIGERIA(Department of Geology and Mining, Nasarawa State University, Keffi, 2005-02-23) Jatau, B.S.; Ajodo, R. O.Thirteen vertical electrical sound points using Schlumberger array method were chosen, outside cultural interference and terrametcr SAS 300c was used to obtain the sounding curves in parts of Kaduna town and environs in the Basement complex of Nigeria. The result were interpreted using Resixp Programme (1992) to quantitatively delineate the various layers, which revealed four to six layers, with their thicknesses and apparent resistivities. The qualitative interpretations were also deduced showing the piczometric, isoresistivity, depth to basement maps and the water potential of the area. The results showed a good correlation with existing geologic and topographic and drainage maps of the study area. Its water potential of the study area varied from one place to another.Item Open Access HYDRAULIC CHARACTERISTICS OF A TYPICAL BASEMENT COMPLEX AQUIFER IN AJAOKUTA, SOUTHWESTERN NIGERIAHYDRAULIC CHARACTERISTICS OF A TYPICAL BASEMENT COMPLEX AQUIFER IN AJAOKUTA, SOUTHWESTERN NIGERIA(Department of Geology and Minning, Nasarawa State University Keffi, 2005-09-09) Osadebe, C.C.; Fatoba, J.O.; Obrike, Stephen E.To establish the feasibility of water supply in a basement complex area of Ajaokuta, Southwestern Nigeria, pumping test results were used to investigate the storage properties and groundwater potential of the aquifer. The aquifer system consists of weathered and weathered/fractured zone of decomposed granitic rock with quartz veins. Kazemi et al. (1969) straight line method (observation well) of draw-down analysis in an unconfined aquifer (0=1) yield fracture transmissivity', fracture storativity and matrix storativity o f57.83 m day, 2.91 X 10٠' and 7.49 « 10 ا respectively. These values are reasonably high. The well efficiency of the test well is 83% and discharge rate of 25m١/hour (6OOmرذ day). The result is reasonably good and indicative of good groundwater potential.Item Open Access A priminary Assessment of Groundwater Quality of Some Shallow Wells around Kaduna Metropolis, North Central, Nigeria(Department of Geology and Mining, Nasarawa State University, Keffi, 2005-10-13) Jatau, B.S.; Ajodo, R. O.This paper presents the results of chemical analyses of groundwater samples obtained from twelve hand-dug wells located in parts of Kaduna town and environs in the Basement Complex of Nigeria. The results are evaluated with a view to determining the quality in terms of the chemistry of the groundwater within this area. The Ca2\ Mg2+, NO?', SO,2- and Cl" concentration level of 0.2 -32.1 mg/I, 0.4 - 2.6 mg/1, 2.0 - 9. 0 mg/1, 3.0 - 12.0 mg/1, and 9.0 - 60. 0 mg/I respectively for water samples are lower than the World Health Organization (WHO 2004) recommended highest desirable level of 75, 59, 45,200, and 200 mg/I respectively. No trace of iron and zinc was found in the area. The total hardness concentration level of 0.19 - 4.88 mg/1 are lower than World Health Organization WHO (2004) recommended highest desirable levels of 100 mg/I. 'flic pi 1 values (3.9 - 5.7 units) falls below the maximum permissible levels of 6.5 - 9.2 units. The piper trilincar diagram shows that the chemical properties of all the sample are dominated by alkaline earths elements. The water is slightly acidic with high percentage of hydrocarbonate ion and low percentage of sulphate and chloride ion. It is concluded that the acidity of the groundwater could be due to pollution from the industry and hence remedial solution suggested.Item Open Access TOPOGRAPHICAL AND GEOLOGICAL SURVEY OF OYO/IWAH MARBLE DEPOSIT IN LOKOJA LGA, KOGI STATE, NIGERIA(Department of Geology and Mining, Nasarawa State University, Keffi, 2005-11-13) Jatau, B.S.; Oyinloye, O. T.; Ogah, V. E.Detail topographic survey and geological traversing/mapping were carried out on the Oyo/Iwah marble deposit, Lokoja Local Government Area, Kogi State. The area is located in Basement Complex terrains of the South Western pan of Nigeria. 1:2000 scale topographical map and geological map of the project area were produced. The topographi- .. cal survey established the spot-heights and topographical features, while geological survey delineated and identifiedy different rock types and their respective boundaries including measurement of appropriate structure features, strike dip foliation. The area of study covers an area of 4km by 2km. The marble appears to have a roughly NE-SW trend, and thins to the South - West. The marble exposure covers an area of 2.5Km2, about 63 % of the surface area, followed by quartzite with an area of 1.20Km2 about 3%. Mica schist has a surface area of .12Km2 about 3%, while Lateritc covers about .lOKm2 of the surface, that is about 2.5% and pegmatite .08 Km2, which is about 2% of the first half of the block. The second half of the block is predominantly covered with mica-schist, quartzite, and pegmatite. The topographic study revealed the highest and lowest spot-height to be 375m and 275m above the sea level respectively. The drainage pattern of the study area is dendritic in nature, mainly drained by rivers Mimi, Opc, and their tributaries.Item Open Access GRAVITY MODELS OF THE BASEMENT STRUCTURE IN PARIS OF ZARIA AND ENVIRONS, NIGERIA(Department of Geology and Mining, Nasarawa State University, Keffi, 2006-09-17) Jatau, B.S.; Ogah, V. E.Gravity survey was undertaken in Zaria and its environs in the Basement Complex of northern Nigeria to locate sub-surface geological structures in relation to mineral prospect of the study area. Measurements were obtained with the use of Lacoste and Romberg gravity meter. The data obtained were subjected to analysis. The results revealed three anticlines and four synclines as geological subsurface structures in the study area. These are concentrated between Gangara, Tandama and Danjo areas. The structures are of interest for detail and further follow-up mineral exploration. Depth estimation by half width technique was used to obtain depth to the bodies responsible for the gravity anomalies. The causative bodies are depicted in two-dimensional models (2D) and found to be deeply deposited.Item Open Access Mineralogical, geochemical, physical and industrial characteristics of shale from Okada area, southwestern Nigeria(Department of Geology and Minning, Nasarawa State University Keffi, 2007-01-09) Obrike, Stephen E.; Osadebe, C.C.; Onyeobi, T.U.S.'•؛:neralogical, geochemical and physical characteristics of the shale from Okada, southwestern Nigeria, were determined to evaluate its industrial potential. The x-ray analysis of the shale shows prominent quartz, kaolinite and mixed layer peaks. The result of the chemical analysis shows the predominance of SiOj (55,71% to 55.84%) and Al o (20.58% to 20.70%) with silica/ alumina ratio of 2.71. This clearly defines the shale as alumino-silicates. The other significant chemical impurities m the clay- shale arc 0,70) ه ع%), TiO, (1.15%) and N aO (2.0%). Mineralogical and chemical compositions suggest that the deposit could be exploited for ceramic, pottery and refractory industries. A small amount of montmorillonite in the clay results in high plasticity (74% - 85%) and shrinkage limit (8.30 - 8.70%) as well as low vitrification. The shلا e is also characterized by high loss on Ignition (16.8%).Item Open Access Physico - Chemical Quality of Ground Water from Shallow Wells in Galambi and Environs, Bauchi State, Northern Nigeria(Department of Geology and Minning, Nasarawa State University Keffi, 2007-03-03) Essien, Queen Ekenem; Anudu, G.K.; Baba, Adama Oleka; Ikpokonte, A.E.Physico-chemical characteristics of ground water from shallow wells in Galambi and its environ in Bauchi State, Northern Nigeria, were evaluated. A total off ifteen shallow well water samples were randomly collected and analyzed for an assessment of its potability and suitability for domestic purposes. Results obtained indicate that the ground water is slightly acidic to moderately alkaline (5.70< PH <8. JO), hard to very hard, (124.7 - 256 mg/1), colourless, and odorless. Conductivity, HCOj2', CO2', NO32', SO2', and PO4' are generally within WHO permissible levels for potable water. However, heavy metals like copper, iron, and lead are of higher concentrations than WHO standards for drinking water. Consequently, relevant treatment procedures are strongly recommended to reduce concentrations of Fe, Cu and Pb in the water so as to minimize the risks/concerns that they may pose to human health within and around the study area. The plot of the average constituents of the ground water in a Piper Trilinear diagram shows that the water is potable and can be classified as .alkaline earth water type with higher alkaline proportion (Ca- Mg -Na) and predominantly HCO3 water, as well as normal alkaline earth water type (Ca- Mg) with predominantly HCO3' water.Item Open Access Hydrogeological Appraisal of parts of Jemaa Local Government Area, North-Central Kaduna State, Nigeria(Department of Geology and Mining, Nasarawa State University Keffi, 2007-09-19) Jatau, B.S.; Bajeh, I.The ground water potential quantity and quality of parts of Jema’a Local Government Area in the Basement Complex of southern part of Kaduna State have been investigated using surface geophysical, hydro- geological and hydro-chemical analysis. The results of the surface geophysical survey, using the resistivity techniques, Horizontal Electrical Profiling (HEP) and Vertical Electrical Sounding (VES) proved effective in locating and assessing the thickness of regolith aquifers. The HEP was used as a reconnaissance survey to select points for VES. Interpretation of the sounding curves obtained from the study area, suggests that the subsurface layering ranges from 3-4 layers. The estimation of aquifer potential from geo-electric sounding was carried out and the result was compared with a simple scheme presented for ranking of VES. The geometric mean of the weighing ranged from 2.5-10.5 with a modal class being 5.6-6.5. The results of the borehole yield using the above parameter showed a good correlation with actual drilling and pumping test data and a good degree of relationship with the geophysical appraisal. The result of the water quality analysis also shows that the water quality in the study area falls within the permissible limit of the World Health Organisation standard for drinking water. The tri-linear diagram revealed that the groundwater in the study area is more with the earth alkaline water with higher alkaline proportion predominantly rich in HCO3'.Item Open Access CHARACTERIZATION OF SOME TYPICAL NIGERIAN PORTLAND CEMENTS(Department of Geology and Mining, Nasarawa State University, Keffi, 2007-11-23) Jatau, B.S.; Aye, A.E.; Onoja, G.This paper presents the results of chemical analyses of Ashaka Portland cement, Burham Portland Cement and Sokoto Portland Cement The results are evaluated with a view of classifying them according to American Standard Testing and Materials (ASTM C150-86) specification and therefore deduce their appropriate uses thereof. The results of the analysis shows that Ashaka Portland Cement constitutes 60.24% CaO, 1.98% Fefi^ 6.73% Al203, 19.45% SiO2, 2.12% S03f 0.78% MgO and 4.6% carbonate carbon. Burham Cement contains 62. 97% CaO, 2.14% Fe203/ 7.28% Al203, 19.07% SO& 1.89% S03 and 1.84% carbonate carbon and Sokoto Portland Cement comprises of 60.18% CaO, 2.69% Fe-fi^ 5.97% Al203, 20.07 SiO% 1.13% MgO, 2.45% S03 and 5.40% carbonate carbon. According to (ASTM C150-86) specification, the result of the analysis shows that Ashaka Portland cement is type I cement which is required for general concrete constructions, Burham Portland cement is type III which usage are suitable for general concrete constructions that require high early strength and Sokoto Portland cement being type IV which is suitable for structural works that require low heat of hydration.Item Open Access Trace Metals in Surface and Subsurface Water in Kaduna South Industrial Area North-Central Nigeria(Department of Geology and Mining, Nasarawa State University Keffi, 2008-01-01) Jatau, B.S.; Bajeh, I.; Innocent, S.This study discusses the analysis of trace elements constituents in parts of Kaduna South industrial area of the Basement Complex of North-Central Nigeria which is necessary to ensure that objectionable elements like Cr, As and Pb whose ingestion in high doses can have serious consequences on the health of the populace, are not significant in the water. In line with this, 22 water samples were obtained, three from boreholes, eleven from surface water and 8 from hand-dug wells and analysed for the presence of 19 trace metals in the study area. The trace metals concentration levels were compared with the regulation. K, Ca, Mn, Zn and Cu were within the maximum contaminant level (mcl) accounting for 23.62% while V, Cr, Fe, Co, Ni, Ga, As, Se, Pb, Br, Rb, Sr, Zr and Mo, whose concentration level exceed the maximum contaminant level (mcl) accounting for 73.68% of the total contaminants. The high percentage of trace metals that exceed the maximum contaminant level suggests that the water within the study area may be classified as been highly polluted and thus unfit for drinking especially regard to Arsenic, Lead and Chromium content. Domestic and industrial waste should be properly disposed and recycled. The government industrial regulating bodies should make conscientious effort to control, regulate and educate the industries and the populace on indiscriminate waste disposal from domestic and industries within the study area.Item Open Access PHYSICAL AND CHEMICAL ASSESSMENT OF MAJOR PORTER AND NAHIJTA KAOLIN DEPOSITS IN BARKIN LADI JOS, PLATEAU STATE, NIGERIA(DEPARTMENT OF GEOLOGY AND MINING FACULTY OF NATURAL AND APPLIED SCIENCE NASARAWA STATE UNIVERSITY KEFFI, 2008-02-21) Moumouni, A.; Ahmed, B. J.; Obaje, N. G; Tanko, I. KPhysical and chemical properties of Major Porter and Nahuta deposits of Barkin Ladi area of Plateau State, Nigeria were investigated. A total of eight (8) samples (Four from each deposit) were collected, processed and analyzed using standard analytical technique. Physical properties like colour, texture, swelling capacities and luster were examined right from the field while others like clay content, plastic limit, liquid limit, were examined in the laboratory. The chemical composition was determined using XRF. Comparison of both physical and chemical properties of the two deposits with industrial specifications reveal that the two kaolin deposits are not suitable for industrial use in their natural state and so will require some forms of benefaction which will range from screening/filtering and blending before it can be used in some of the industries.Item Open Access Petrological and Proximate analysis of Obi-Lafia coal, Nasarawa State, Central Nigeria(Department of Geology and Mining, Nasarawa State University Keffi, 2008-11-18) Jatau, B.S.; Amoka, I.S.; Oyeladum, O.A.WPreliminary visual examination of Obi/Lafia coal revealed vitrain, clarain and fusain. Petrological studies established that the coal contained vitrinite, extrinite, fusinite (fossil) and mineral substance mostly pyrite.Examination with research microscope(x20) showed vitrinite to be 70%, Extrinite 14%, fusinite 2% and mineral substance (mostly pyrite) 14%. Proximate analysis revealed 4.33% moisture content,35.66% volatile matter. 9.6% ash content and fixed carbon 50.34%. The density of the coal was 1.26 and inorganic matter 16.54%. Ultimate analysis revealed 3.21 % sulphur content. Samples were heated to about 900°C, it forms cake but breaks with slightly strong pressure applied, which indicates it is probably medium coking.Item Open Access THE EFFECTS OF CALCINATION ON THE BENEFICIATION OF KOTON KARFE IRON ORE(Department of Geology and Mining, Nasarawa State University, Keffi, 2008-11-22) Dunga, George Thomas; Jatau, B.S.; Yaro, S. A.The effects of calcination on the beneficiation of Koton Karfe iron ore was investigated, the Koton Karfe iron ore is located in Igbide village of Lokoja local Government area of Kogi State, Nigeria with a proven resetwe of850million tonnes. The ore samples were source from two different pits of land 2, 400m apart with pitl sample collected 6m deep beneath the outcrop. The chemical and mineralogical characteristic of the ore samples was investigated using X-ray diffractometer [XRD], X-ray Fluorescence Spectrophotometer [XRFJ, gravimetric method of chemical analysis and metallographic techniques. The results of the chemical analysis revealed that the Koton Karfe iron ore of pit 1 contained a total iron content (43.40% Fed, 10.14% (SiOd, 1.24% calcium (Ca), 0.70% manganese (Mn), 0.10% and 0.0051% strontium (Sr) while pit2 contained 0.9% Titanium (Ti), 1.56% manganese, 26.50%Fer, 0.041% zircon (Zr), 0.0020%nobium(Nb) and 39.48%oSilica(SiOd, Phosphorus (P) and Sulphur (S) were beyond the limit of detection in both the samples of pit land 2 of the ore deposit. The results obtained from the calcination action on the sample of pitl revealed that calcination have greater effects on the ore in which the action lead to the increased in the total iron from 43.40% of the head sample to 64.80% after calcination and then 69.10% after concentration using magnetic separation technique at sieved size fraction - 180 -rJ25um while silica contents of the various sieved size fractions samples decreased in the reversed manner, also the physical magnetic property of the ore sample improved thereby enhancing better recoveries values of the various concentrated sieved size fractions. These values obtained for the sieved size fractions and concentrates after calcination and concentration could be used for blast furnace process for sinters production and super concentrates for pellets production because the values compared favourable with 63% and 66.80% stated for the both processes, thus making Koton Karfe another potential source of iron ore deposit in Nigeria.Item Open Access Geotechnical analysis of two Nigerian soils for use as clay liners(Department of Geology and Minning, Nasarawa State University Keffi, 2009-01-04) Obrike, Stephen E.; Osadebe, C.C.; Omoniyi, S.S.The cretaceous Auchi shale and the Tertiary Imo shale in SW Nigeria were investigated for their suit- ability for use as a clay seal in waste disposal landfills. Geotechnical analyses indicated they are highly plastic inorganic clays. Although their geotechnical and chemical properties were within the range suggested by various authors for use as mineral seals, care would need to be taken with the Okada shales as they contain smectite and would be difficult to work and liable to cracking.Item Open Access SOCIO-ECONOMIC IMPACTS OF ARTISANAL AND SMALL-SCALE MINING (ASM) IN NASARAWA STATE, CENTRAL NIGERIA(Department of Geology and Mining, Nasarawa State University, Keffi, 2009-01-26) Jatau, B.S.; Amoka, I.S.Artisanal and Small-scale Mining (ASM) has recently received increased local and international attention. This paper aims at providing a balanced overview of the positive and negative impacts of Artisanal and Small-scale Mining (ASM) in Nigeria, with particular reference to Nasarawa State. The benefits and hazards are reviewed and policy response and implementation strategies are suggested. Presently, the hazards of ASM seem to outweigh its benefits in Nasarawa State and generally in Nigeria. However, ASM could make a sound socio-economic and environmentally friendly impact in Nigeria if the operators, stakeholders, authorities, government, financial institutions, donor agencies and non-governmental organizations (NGO) would make concerted efforts to regulate, guide, improve and encourage the industry.Item Open Access DETERMINATION OF THE WEATHERED REGOLITH USING SEISMIC REFRACTION METHOD IN PARTS OF KADUNA SOUTH INDUSTRIAL AREA, KADUNA NIGERIA.(Department of Geology and Mining, Nasarawa State University, Keffi, 2009-06-23) Jatau, B.S.; Achie, AlheriSeismic refraction method of geophysical survey was carried out in parts of Kaduna South Industrial Area, Kaduna North-West Nigeria. Nine shooting points were taken at various points of interest using an ABEM instrument (MK 6 Seismograph) outside cultural interferences. The readings were taken at about 1 to 2km apart. Twelve channel geophones were laid from the shot point at 5m separations along the profile to pick up the seismic wave. Quantitative data interpretation of the travel-time was done using computer processing package. The no of layers, velocities and the thicknesses of unconsolidated material above the bedrock (Depth to bedrock) in the area of study were determined. Three to four layers were encountered, consisting of the Topsoil (Dark brown laterite, lateritic clay), (silty clay, orange brown laterite to kaolinitic clay and saturated sand), (Biotite and granite gneiss) and fractured/weathered basement rock. The average depth to the basement was found to be about 13m, the shallowest and deepest depth to the basement was found to be about 10m and 16m respectively. The qualitative interpretations in terms of layer velocities, thicknesses and histogram/frequencies plots were deduced and drawn. Seismic sections were compared with existing geology which showed a good degree of correlation. The second layer from the study area being mostly clay (1020-1630) m/s could cause differential settlement in foundations hence the need to remove it prior to foundation is of paramount importance.
