“…The depth to the probable geothermal reservoir is below 2 km up to 4 km, which is in agreement with calculated depths from geothermometry analyses of Saibi (2018) . Saibi et al. (2020) estimated the temperature of the geothermal reservoir at AMGA of 147 °C using cation geothermometers.…”

“…Potential field data (gravity and magnetic) were collected in the study area during 2017. The gravity data were acquired using Scintrex CG-6 gravity-meter and the data was corrected for tilt, tide, topography, location, drift and Bouguer density ( Saibi et al., 2019 , 2020 ) in order to calculate the Bouguer anomalies. The magnetic data were acquired using a Geometrix G-856 AX Proton magnetometer ( Mohamed and Saibi, 2017 ; Saibi et al., 2017 ; Saibi, 2018 ).…”

“…Al-Mubazzarah is also known for its hot springs, which provide therapeutic thermal waters for baths throughout the year. The temperature of the hot spring water averages about 40 °C ( Saibi et al., 2020 ). The sources of the hot water and the size of the hydrothermal reservoir are still unknown.…”

Geothermal manifestations (hot springs) emerge in the Al-Mubazzarah Geothermal Area (AMGA), Al-Ain city, Abu Dhabi Emirate, United Arab Emirates. This paper presents the application and results of a Magnetotelluric (MT) survey, which was carried out in 2017 at the AMGA geothermal field. The MT method was used to investigate the variations in the electrical conductivity beneath the AMGA. This study focuses on characterizing the patterns of subsurface electrical conductivity of the AMGA geothermal reservoir. Dimensionality analysis of the measured MT data indicate that 2D inversion is appropriate for the subsurface resistivity interpretation. The inversion results support a model consisting of three resistivity-defined layers; from top to bottom they are: (1) a shallow layer with resistivity ranging from 10 to 20 Ωm, representing recent alluvial and windblown deposits, (2) a second conductive layer with resistivities less than 10 Ωm, beneath the first layer. This layer is recognized as the Tertiary carbonate sequence in the region, (3) a deep, moderate to relatively high resistive zone, 10–30 Ωm beginning at 800 m depth and reaching 4 km depth in the northern part of the profile, representing Mesozoic basement rocks. The observed moderate to high resistivity zone (10–30 Ωm) in the 2D model may represent a region where the hot groundwaters originated (geothermal reservoir), with the hottest geothermal located at a depth greater than 4 km. The geothermal reservoir zone is also represented by a low to high density contrast and a low to moderate magnetic susceptibility, as indicated in the inverted potential field data models, and confirmed the existence of a north dipping major fault.
