Thermal gradient profiling in the AGF. a Vertical variation of thermal gradient profiles based on 10 m regular downhole temperature measurement steps. b–d Mean thermal gradient distribution per segment in various lithological units. Mean values are relative to the segments in the temperature profiles with common features: continuous temperature distribution, stratigraphic affinities, isothermal evolution, and significant changes in slope of the temperature profiles
