Studies in the Abu Dhabi Emirate, near Madinat Zayed and Liwa, identified high geothermal gradients and high-heat-flow areas. This study employed broadband magnetotelluric (BBMT) measurements to map the geological formations, focusing on the basement rock structures linked to the high-heat-flow anomaly observed in the area. The three-dimensional inversion of BBMT data revealed a high-resistivity anomaly at 10 km depth beneath a highly conductive Quaternary sediment layer in the high-heat-flow area interpreted as basement rocks. To interpret the MT model, gravity, magnetic, seismic, and heat flow data were used, and a two-dimensional gravity-magnetic model was constructed along the BBMT profile. The high-heat-flow anomaly in the study area is interpreted as due to the existence of highly magnetized basement rocks.
