|Title:||Delineation of subsurface layers using resistivity imaging techniques in coastal blocks of Thiruvallur District, Tamil Nadu, India|
|Keywords:||Geoelectrical imaging;Vertical Electrical Sounding;Conductance;Anisotropy and Groundwater|
|Abstract:||Based on the interpreted results of Vertical Electrical Sounding three to five subsurface geoelectrical layers have been delineated. Various thematic maps such as iso-resistivity contour of different layers, iso-apparent resistivity contour maps, transverse resistance, longitudinal conductance and anisotropy contours have been prepared. In addition, using geoelectrical imaging technique, geoelectric pseudo sections and geoelectric resistivity sections along different directions have been prepared. The disposition and vertical extensions of formations have been deciphered encountered through this technique. The results of studies arrived at by geoelectrical imaging technique are correlated with the drilling data and a good match of interpreted VES data with the borehole litho log and electrical log.|
