The Upper Benue basin being part of Benue basin is believed to be rift valley and is expected to be a major depositional basin, because rifting structures are often good sites for mineralization. The strategic economic importance and the availability of data from the study area arose the interest of many researchers including this present work to focus their attention on the area in search of geological features that are favourable to mineral deposition in the basin. In this work, the interpretation of the data extracted from the aeromagnetic map of Kam, an area in the upper Benue basin which covers from latitude 0800’ to 0830’ N and longitude 1100’ to 1130’ E was carried out using a semi- automated techniques involving the analytic signal technique to delineate linear geologic structures such as faults, contacts, joints and fractures within the study area in a bid to unravel the gross subsurface geology of the area which would in no doubt help in better understanding and characterization of the area investigated. The residual magnetic field data was subjected to a filtering technique, the analytic signal which was employed to study source parameters which include location, depth and susceptibility contrast of the identified magnetic anomalies in the basement rocks. The results obtained from both profiling curves and depth contour map showed that the study area is magnetically heterogeneous and the basement is segmented by faults. Based on the results obtained from both profiling curves and depth contour map, it was revealed that the study area is divided into three basinal structures; deep sources ranging between 5km and 8.5km and the area is recommended for further investigation especially for its geothermal energy potentials. The intermediate depths between 2km to 4.5km correspond generally to the top of intrusive masses occurring within the basement, a depth deep enough for possible hydrocarbon deposit. Shallow depths between 0.01km and 2.5km are attributed to shallow intrusive bodies or near-surface basement rocks probably isolated bodies of ironstones formation concealed within the sedimentary pile. <#LINE#> @ @ Sunmonu L.A. and Alagbe O.A., Groundmagnetic Study to Locate Burried Faults (A Case study of Abandoned Local Government Secretariat in Ogbomoso), Int.

Subhorizontal and subvertical lineations are recorded from granite exposures in the field. The above features suggest that the granites were emplaced during a transpressive tectonic Achankovil shearing of Pan-African time. <#LINE#> @ @ Cloos E., Oolite deformation in the South Mountain fold, Maryland, Geol Soc Am Bull, 58, 843 – 918 (1947) @No $ @ @ Ramsay J.G., Folding and Fracturing of Rocks, McGraw – Hill, New York, 568 (1967) @No $ @ @ Dunnet D., A technique of finite Strain analysis using elliptical particles, Tectonophysics, 7, 117 – 136 (1969) @No $ @ @ Fry N., Random point distribution and strain measurement in rocks, Tectonophysics, 60, 89- 105 (1979) @No $ @ @ Ramsay J.G. and Huber M.I., The Techniques of Modern Structural Geology, 1, Strain analysis, Academic Press, London (1983) @No $ @ @ Manimaran G., Deepak Bagai and Roy Chacko P.T., Chrysoberyl from southern TamilNadu of South India, with implication for Gondwana studies, In: Mineral Exploration, Recent strategies, Eds Rajendran S. et al., NIPA, New Delhi 63-76 (2007) @No $ @ @ Manimaran D. and Manimaran G., Tectonic studies around Vallanadu area, Tuticorin district, Tamil Nadu, Outreach, 5, 117 – 122 (2012) @No $ @ @ Manimaran G., Roy Chacko P.T., Manimaran D., Selvam S., Antony Ravindran A., Besheliya J. and Sugan M., Shear lineament Analysis of Ambasamudram-Tenkasi Transect of Achankovil-Tambraparni shear zone, South India, IRJ Earth sciences, 1 (3), 1-10 (2013) @No $ @ @ Hudleston P.J., Schultz Ela D. and Southwick D.I., Transpression in an Archaean greenstone belt, Northern Minnesota, Can., Jour Earth Sci, 25, 1060-1068 (1988) @No $ @ @ Guru Rajesh K. and Chetty T.R.K., Structure and tectonics of the Achankovil Shear Zone, Southern India, Gondwana research, 10, 86- 98 (2006) @No $ @ @ Braun I., Pan-African granitic magmatism in the kerala Khondalite belt, Southern India J Asian earth sci, 28, 38-45 (2006) @No $ @ @ Bhattacharyya P. and Hudleston P., Strain in ductile shear zones in the Caledonites of Sweden: a three- dimentional puzzle, Jou Struc Geo, 23, 1549-1565 (2001) @No $ @ @ Chetty T.R.K. and Bhasker Rao Y.J., Behaviour of stretching lineations in the Salem-Attur shear belt, Southern Granulite Terrain, South India, Jour Geol Soc India 52, 443-448 (1998) @No $ @ @ Manimaran G., Petrological and structural studies of the North western part of the Tambraparani shear Zone, South India, Unpubl, Ph.D Thesis Univ of Kerala, Trivandrum, India, 289 (1995) @No <#LINE#>Assessment of shallow Aquifer Potential zone using Electrical Resistivity Scanning Techniques Compare with Borehole Lithology in Western part of Lower Vellar basin, Chidambaram Taluk, Cuddalore,Tamilnadu, India<#LINE#>C.@Dushiyanthan,Raja Kumar T.@Jeyavel,K.@Karthikeyan,D.@Davidraju,B.@Thiruneelakandan ,R.@Suresh<#LINE#>30-34<#LINE#>3.ISCA-IRJES-2014-002.pdf<#LINE#>Department of Earth Sciences, Annamalai University, Annamalai Nagar, INDIA @ Department of Civil Engineering, Annamalai University, Annamalai Nagar, INDIA @ Govt Engineering College, Tirunelveli, Tamil Nadu, INDIA<#LINE#>3/2/2014<#LINE#>15/2/2014<#LINE#>Six multi-electrode resistivity scanning techniques has been conducted shallow aquifer potential zone in western part of lower vellar basin.

We used NmF2 data of two stations Athens and Sanvito. We calculate Karl –Pearson coefficient of correlation. Results of the study showed that Karl- Pearson Coefficient get maximum disorder before two days from the seismic shock. It may be due to the generation of seismic wave during earthquake, which propagate upward and perturb the F-region ionosphere. Results may be beneficial in seismic precursor study. <#LINE#> @ @ Pulinets, S.A., Legen’ka, A.D.

Such bulk chemical analyses are very useful. To understand fully the geochemical processes and the evolution of various types of sediment or differentiates, chemical analyses needed. Chemical data has value for classification, but the limitations of using chemical data for classification must be identified. The Cretaceous formation of Ariyalur area, Tamilnadu is one of the best developed sedimentary formations in southern India. The staratigraphy of this formation is divided into three groups, Uttatur, Trichinopoly, and Ariyalur. The Trichinopoly group later designated as Garudamangalam Formation. Representative 10 sandstone samples were collected from the Garudamangalam formation, and analysed for major oxide composition by using XRF. The relative concentrations of three major groups- silica, alumina, alkali oxides plus magnesia have been used to classify the Garudamangalam sandstone samples. From the study area samples SiO ranging from (12.93-42.56%), Al (3.49-8.47%), Fe(2.29-22.02%) and strongly depleted to S, NaO, KO, MnO, TiO and . The very high content of CaO ranging from 23.53-45.90%, it indicates they are rich in calcite cement, or it may mean shell fragments in the sandstone particles. Based on the following reference set, guidelines are proposed for chemical classification of sandstones. 1.quartz arenite: log(SiO/Al1.5, 2.Greywacke: log (SiO/Al)1 and log(KO/NaO)03. Arkose(includes subarkose): log(SiO/Al)1.5 and log(KO/NaO)0 and log (Fe+MgO)/ (KO+NaO)04. Lithic arenite: log(SiO/Al)1.5 and eighter log(KO/NaO)0 or log(Fe+MgO)/ (KO+NaO)0. If log (KO/NaO)0, lithicarenite can be confused with greywacke. Based on the above guidelines the study area sandstone samples reflects log (SiO/Al ratios from 0.47 to 0.92. The log (KO/NaO) Vs log (Fe+MgO)/ (NaO+KO) scatter diagram shows lithicarenites field. The study area samples reveals that they are rich in Litharenite sediments are evidences of a probable deposition of the felsic rich source rock and deposited in a marine environment. <#LINE#> @ @ Banerji R.K., Stratigraphy and micropalaeontology of Dalmiapuram Formation (Lower Cretaceous) – A rock stratigraphic unit of South India, Jour.Pal.Soc.India, (15),32-41 (1972) @No $ @ @ Banerji R.K., Evolution of the Cauvery Basin during Cretaceous, Proc.
