“…Geophysical investigations play an important role in advancing our understanding of the lithospheric transformation, crustal and mantle structure (Le Pape et al, 2012;Gao et al, 2013Gao et al, , 2020a. Generally, geophysical investigations are often used to identify magma heat source in the exploration of geothermal resources (Huang et al, 2015;Gao et al, 2020a, b;Pan et al, 2021). It should be noted that a better understanding of geological structure helps to interpret geophysical data.…”

“…Fluids play a key role in the transportation of heat and mass (Menzies et al, 2014;Jiang et al, 2018;Pan et al, 2021) and provide important information on the heat sources and genesis of geothermal systems (Guo, 2012;Jiang et al, 2019b;Kong et al, 2020b;Pan et al, 2021). The input of magmatic fluids can influence the geochemistry of geothermal fluids in high-temperature geothermal systems with magma heat sources (Guo, 2012(Guo, , 2020Guo et al, 2019;Pan et al, 2021). Generally, these geothermal fluids often have high Cl, trace elements, such as B, As, Li, Rb, and Cs concentrations as in e.g., Yangbajing, Tengchong Rehai and Yellowstone National Park (Truesdell and Fournier, 1976;Guo, 2012Guo, , 2020Guo et al, 2019), and 2 H, 18 O isotope values due to the effects of magmatic volatiles (Liu et al, 2019;Pan et al, 2021).…”

“…In addition, the rock types should be considered, keeping in mind that geothermal reservoirs can be hosted in multiple rock types with different thermal properties. Finally, faults also play a key role in the transportation of fluid and heat (Kong et al, 2020b;Pan et al, 2021), and many high-temperature geothermal systems reside in fault interaction zones (Jolie et al, 2021). Among all the above-mentioned factors, heat sources have a fundamental influence on the distribution of subsurface temperature, whether the geothermal system has high-temperature or not.…”

It is common sense that a deeper well implies higher temperature in the exploration of deep geothermal resources, especially with hot dry rock (HDR) geothermal resources, which are generally exploited in terms of enhanced geothermal systems (EGS). However, temperature is always different even at the same depth in the upper crust due to different heat sources. This paper summarizes the heat sources and classifies them into two types and five sub-types: crustorigin (partial melting, non-magma-generated tectonic events and radiogenic heat production), and mantle-origin (magma and heat conducted from the mantle). A review of global EGS sites is presented related to the five sub-types of heat sources. According to our new catalog, 71% of EGS sites host mantle-origin heat sources. The temperature logging curves indicate that EGS sites which host mantle-origin magma heat sources have the highest temperature. Therefore, high heat flow (>100 mW/m 2 ) regions with mantle-origin magma heat sources should be highlighted for the future exploration of EGS. The principle to identify the heat source is elucidated by applying geophysical and geochemical methods including noble gas isotope geochemistry and lithospheric thermal structure analysis. This analytical work will be helpful for the future exploration and assessment of HDR geothermal resources.

Studying initial geothermal fluids and tectonic active zones is crucial for exploiting intermediate high‐temperature geothermal resources. This study aims to investigate the genesis, circulation and environmental implications of geothermal water in the Riduo–Cuona Rift (RCR) of the eastern Tibetan Plateau. By integrating hydrochemical analysis, stable isotope geochemistry (δ2H, δ18O and 87Sr/86Sr), and noble gas isotope characteristics, the research seeks to develop comprehensive geothermal circulation models in the RCR. (M1) The spatial distribution of geothermal waters near the molten magmatic domes indicated 87Sr/86Sr ranges consistent with those of the rock, respectively. The high Ca, Mg ‘hardness’ spring waters were attributed to strata surrounding the dome resulting from the last leaching, as confirmed by the estimated higher hydraulic head, mainly located in ‘immature water.’ (M2) The spatial distribution of geothermal waters corresponding to an orogenic belt revealed HCO3·SO4–Na as the dominant hydrochemical facies in the northern RCR. Research suggests that springs exhibit greater circulation depths and that spring solute SO4 is related to the Gangdise magmatic arc leaching. (M3) However, the active tectonic zone's springs 87Sr/86Sr (0.705763–0.709754) indicated evaporite characteristics. The thermal reservoir temperature in this structural junction zone is the highest (256.75°C–287.03°C). The high trace alkali element concentrations, particularly of B, F and As, exceeded the WHO guideline; the drainage system analysis indicates regional nonnegligible environmental risks in the Gudui. Establishing these models can clarify the relationships between geothermal fluids, tectonic structures and regional faults, providing insights into geothermal resource potential, environmental risks and possible strategies for sustainable resource exploitation in the region.
