A remote reference audio-magnetotelluric (AMT) study has been carried out in Bakreswar Geothermal Province to map the possible geothermal reservoir of the area. The heat flow of BGP is two and half times of average global heat flow and is nearly equal to that of young oceanic ridge. A NS (∼16 km) profile delineated a geothermal reservoir of resistivity less than 10 ohm-m at a depth of about 3 km of large horizontal extent(>2 km). The sensitivity analysis suggests that the delineated reservoir is less sensitive. BGP belongs to high temperature volcanic region which is dominated by meteoric fluid. These fluids are heated at greater depth and rises by convection to near-surface depths, where it is entrained into the overall pattern of groundwater flow. BGP thus supports the conceptual model of magmatic geothermal plays volcanic field rather than hydrothermal alteration.
