Novel insights into the deep geothermal processes in the collapsed continental orogenic belt based on the evolution analysis of multi-hierarchy geothermal water flow systems

We tried to understand the geothermal water flow system by jointly employing data of hydrogeochemistry and compositions of H/O/He/Ne isotopes and radioisotopes 39Ar, 85Kr, and 14C of geothermal fluids. The findings offer insights into the spatial variations of temperature, helium concentration, and isotope compositions in geothermal fluids within the orogenic belt, and thus improves our understanding of the dynamics of deep geothermal processes in regions of orogenic belts, which is critical for future geothermal energy development in these regions.本研究通过联合运用水文地球化学（hydrogeochemistry）数据，以及地热流体的氢（H）、氧（O）、氦（He）、氖（Ne）同位素组成与39Ar、85Kr、14C等放射性同位素（radioisotopes）数据，以解析地热水流系统。研究结果揭示了造山带（orogenic belt）内地热流体的温度、氦浓度及同位素组成的空间变化特征，进而加深了我们对造山带区域深部地热过程动力学机制的认识，这对该区域未来地热能源开发具有关键意义。
