Map showing general geology and tectonic features of the Ganga basin and adjoining regions, including the buried Faizabad Ridge as a NE-to-NNE extension of the Bundelkhand craton (Sastri et al., 1971; Rao, 1973). Major geological and structural features as well as basement depth contours shown in this figure are taken from the shape files available at the BHUKOSH portal of Geological Survey of India (http://bhukosh.gsi.gov.in/Bhukosh/MapViewer.aspx). Basement depth contours are derived from the aeromagnetic data (Agocs, 1957). Orange circles are the MT sites along the four profiles. Abbreviations are: ADFB - Aravalli Delhi Fold Belt, BKC - Bundelkhand Craton, BTZ - Bundelkhand Tectonic Zone, DHR - Delhi-Haridwar ridge, DVP - Deccan Volcanic Province, FR - Faizabad Ridge, GBF - Great Boundary Fault, GD - Gandak Depression, LF - Lucknow Fault, MDF - Mahendragarh-Dehradun fault, MF - Moradabad fault, SC - Singhbhum craton, SD - Sharda Depression, VB - Vindhyan Basin.
