Abstract: In order to evaluate the subsurface geological structures and thermal properties pertinent to hydrocarbon development, this study presents the findings of an investigation of aeromagnetic data over Guyuk and the surrounding areas. The values of Total Magnetic Intensity (TMI), which vary from -3.6 to 238.1 nT, show complicated tectonic settings with main NE-SW trending anomalies and minor NW-SE characteristics. Deeply buried magnetic sources and spectral blocks utilized for depth estimation are highlighted by upward continuation and gridding techniques. Depth to the top boundary ranges from 4.51 to 6.00 km (average 5.01 km), indicating substantial sedimentary cover, whereas depth to the centroid varies between 10.30 and 16.50 km (average 12.43 km). The comparatively chilly and thick crust is reflected in the Curie Point Depths, which range from 15.80 to 27.61 km (average 19.89 km). A stable thermal regime that supports hydrocarbon maturation is indicated by thermal characteristics such as heat flow (52.53 to 91.78 mW/m2, average 76.01 mW/m2) and geothermal gradients (21.01 to 36.41 °C/km, average 30.40 °C/km). These results provide credence to the area's potential for producing gas and oil.
