Temporal and spatial radiogenic heat production rate of granitic plutons from the Eastern Pontides Orogenic Belt, NE Turkey: Constraints for the geothermal resources

Current status and potentials of enhanced geothermal system in the Eastern Pontide Orogenic Belt, Turkey

“…In contrast, the contribution of K is relatively low, averaging less than 13%, which is closer to the global average. This indicates that the radiogenic contribution of U in the EPOB is relatively high, which is consistent with the results obtained by Arslan et al, (2023). Statistical results show that the Th/U ratios of the granites in the study area vary between 1.9 and 14.554, with an average value of 5.45, which is consistent with the average Th/U ratio of 4.2 in the upper crust (Van Schmus, 2013).…”

“…One of the effective uses of geothermal resources is EGS studies, and the effective implementation of these EGS studies in countries such as France and Australia serve as a promising indicator for the prospective integration of granites with advanced thermal capacity as an important component in the global energy supply paradigm. These advances highlight the potential of EGS technology to harness the abundant thermal energy latent in geological formations, thereby signaling a feasible and sustainable solution to meet the ever-increasing global energy demand (Vigneresse et al, 1987;Chen, 2010, Omenda et al, 2012Zhang et al, 2014;Arslan et al, 2023). EGS is a conceptual approach in which a series of fractures are deliberately created in a high-temperature (radiogenic) granite at a depth of 2 to 5 km.…”
