|Abstract:||Magnetotelluric method gives information of electric property of subsurface at deeper depth and it is also cheaper. Study area of this work is Roorkee-Gangotri region which lies in Himalaya. Himalaya has very interesting geological structure and features. Recent year's magneto telluric method is using to explore new information about it. In the present thesis, I have used, MT2DInvMatlab, a 2D inversion programe to invert MT data from Himalayan region. In this dissertation, magnetotelluric data were acquired using Phoenix system at 7 stations. Phoenix data processed with software (PRC-MTMV and SSMT 2000) based on multi-level robust averaging scheme. Other 35 station data recorded by metronics system (Israil et al, 2008) were added. Total 42 station data were averaged to 18 station data , of good quality. Inversion of these 18 station data was done by MT2DInvMatlab programe to " conclude the information about subsurface of Roorkee-Gangotri region. Inverted resistive section shows different electrical structure beneath Roorkee-Gangotri region. It shows shallow conductive sediments between Indo-Gangetic Plane and Lesser Himalaya, and high resistivity top of Indian crust. It also depicts a conducting zone might be related with the strain accumulation zone in Himalayan region.|
