| Abstract | 2-D inverse modelling of magnetotelluric (MT) measurements at 101 locations in a 40 km by 10 km wide band crossing the Rotorua and Waimangu geothermal fields suggest that the geothermal fields are fed by up-flow zones that rise from the edge of a single electrically conductive body situated between the geothermal fields at about 6 km depth. The conductive body is interpreted to be a zone of silicic magma. |
