Abstract: Geoelectric sounding technique and laboratory analytical methods were used to investigate the effect of certain physicochemical parameters deemed to influence soil corrosivity within some pipeline host communities in Bayelsa State, Nigeria. Eight vertical electrical soundings (VES) were systematically conducted using the Wenner four pin configuration method while soil samples were collected at a depth of 1.5m from twenty four boreholes drilled in the vicinity of the soundings and analyzed for pH, moisture content, chloride, sulphate, carbonate, oxidation-reduction potential and resistivity using standard methods. The overall analytical results show that the soils fall into the mildly corrosive to moderately corrosive categories as regards their effect on buried metallic installations. The designated corrosivity status of each soil sample was determined based on the aggregate concentration of the various analyzed physicochemical...........

Abstract: Aeromagnetic data of Mambila plateau have been interpreted qualitatively and quantitatively using two methods: standard Euler deconvolution and forward and inverse modeling methods. The area is marked by both high and low magnetic signatures (which range from -129.9nT to 186.6nT) which could be associated to several factors like difference in magnetic susceptibility, variation etc. 3D Euler deconvolution depth estimation for structural index (SI = 0.3 and 0.5) ranges from -213.9 m to -2112.0 m and -239.9 m to -2374.9 m, respectively. Depth estimate of forward and inverse modeling for profiles P1, P2, P3, and P4 are 2372m, 2537m, 1621m, and 1586m, with susceptibility values of 0.0754, 0.0251, 0.0028, and 0.001 respectively. This suggests that the bodies causing the anomaly are typical of igneous rocks; basalt and olivine, intermediate igneous rock; granites, and rocks mineral (qaurtz).
Keywords: Mambila plateau, Aeromagnetic interpretation, forward and inverse modeling, 3D Euler deconvolution.

Abstract: In Recent, The Geological Study Of Any Spatial Unit Is More Techno-Centric As Well As Simplified Due To Rapid Technological Growth. Most Perhaps No Body Can Ignore This Realization. As So Far The Study On Geology Of Rajmahal Trap Here Is Completely Based On Literature Study Which May Claim Maximum Efforts As True Documentation Behind This Endless Investigation. The First Way Of Explanation Of The Study Is Formation Of Rajmahal Trap And Next Point Should Be Entertained On Spatial Efficiency, Has To Be Measure By The Study Of Resource Base Within Locality. Therefore, Whole Enquiry Is To Be Set As Regional Approach Rather Than Systematic Method..
