An Integrated Geophysical Studies for Discovery of Lamproites near Ramaduugu Area, Nalgonda District, Telangana State, India

G. Sriramulu, G. Ramadass, Dubba Vijay Kumar


Abstract: The very low frequency (VLF), total magnetic and radiometric precision measurements were performed along seven lamproite profiles, five at the Ramadugu (R1 to R5) and two at Yacharam (Y1 to Y2) lamproite bodies, in the north western margin of the Cuddapah basin, Nalgonda district, Telangana State, India have been mapped subsurface geological structures, i. e. , dykes, faults and fractures. In particular, the disposition and extent of the dykes, contact between dykes and granitic rocks and bed rock topography was traced and its relation with the other geological members of the region examined. The VLF-EM results of 2-D inversion current density plots for profiles Ramadugu and Yacharam lamproites are presented in Figures (2 to 8). The data analysis revealed the presence of positive and negative amplitude of filtered real and imaginary components for identification of conductive body. High positive (red color) values indicate the presence of conductive subsurface structures while lows (black color) are indicates resistive formations. The cross-over of real and imaginary components along the profiles possibly indicating as fractures/fault related depression zones are sometimes recognizes as shear zones). The VLF-EM responses of lamproite bodies along with the magnetic and radiometric interpretation, are presented here as a case study.
