Geophysical survey involving Schlumberger Vertical Electrical Sounding, 2-D imaging dipole–dipole technique and ground magnetic method were carried out along Ibadan-Ife Highway located in the Precambrian Basement Complex of Southwestern, Nigeria to examine geological factors responsible for pavement failure. This was with view detailing subsurface geoelectric sequence, mapping structural features within sub-grade soil delineating bedrock relief as a means establishing cause(s) road The...
Due to several complexities associated with the equatorial ionosphere, and significant role which total electron content (TEC) variability plays in GPS signal transmission, there is need monitor irregularities TEC during storm events. The SCINDA receiver data at Ile-Ife, Nigeria, was analysed a view characterizing ionospheric response geomagnetic storms on 9 March 1 October 2012. Presently, positive effects, peaks were prompt penetration of electric fields changes neutral gas composition...
The effect of the main phase two intense geomagnetic storm events which occurred on August 6 and September 26, 2011 equatorial ionosphere have been investigated using Global Positioning System (GPS) data obtained from an Ile–Ife station (geomagnetic lat. 9.84 ∘N, long. 77.25 ∘E, dip 7.50∘). Total Electron Content (TEC) profiles during geomagnetically disturbed days were compared with quiet time average to examine response ionosphere. results showed that intensity both at night-time...
This study carried out a seismotectonic analysis of parts Togo-Benin-Nigeria shield by delineating and characterising crustal discontinuities using gravity bouguer anomaly data. was with view to understand the significance seismicity area. Three dimensional (3-D) Euler deconvolution horizontal gradient magnitude (HGM) at varied upward continued layer were applied on filtered data highlight determine their dip directions. The result showed that 89 lineaments mapped as faults/fractures from...
The effect of the main phase two intense geomagnetic storm events which occurred on August 5 - 6 and September 26 27, 2011 equatorial ionosphere have been investigated using Global Positioning System (GPS) data obtained from an Ile-Ife station (geomagnetic lat. \ang{9.84}N, long. 77.25 degree E, Dip \ang{7.25}N). Total Electron Content (TEC) profiles during geomagnetically disturbed days were compared with quiet time average to examine response ionosphere. results showed that intensity both...
<title>Abstract</title> This study is intended at depicting the aquifer plausible zones in Modomo/Kajola, Ile-Ife using Dar Zarrouk parameters. The area situated amid latitudes 830,00–830,500 mN and longitudes 663,500–664,000 mE, overlying pegmatite granite gneiss basement complex terrain. Twenty-eight (28) Schlumberger-array vertical electric soundings (VES) were carried out within with help of Terrameter SAS 300C. VES interpretation result reveals three to five geo-electric layers:...
Vertical Electrical Sounding (VES) was carried out at Laniba area, Ibadan, Oyo state, Nigeria in order to study the subsurface geologic layer with view of determining depth bedrock and thickness layers. The ABEM terrameter (SAS 300B) used for data acquisition twenty two (22) VES stations. field obtained has been analyzed using computer software (IPI2win) which gives an automatic interpretation apparent resistivity. results revealed heterogeneous nature geological sequence. sequence beneath...
