Occurrence of geothermal resources and prospects for exploration and development in China
Under the background of China’s energy structure optimization, environmental protection, energy conservation, and rising pressure of emission reduction, geothermal, as a potential strategic replacement energy, has ushered in new opportunities and challenges. This paper systematically summarizes the domestic achievements in the exploration and development of geothermal resources, analyzes the endowment, distribution, and accumulation mechanism of geothermal resources in China, and points out the main problems existing in the exploration and development of geothermal resources in China. On this basis, it looks forward to China’s urgent geothermal exploration and development work and key technologies to be urgently developed, providing important guidance for China’s geothermal science and technology innovation and rapid industrialization development.

Machine Learning for Geothermal Resource Exploration in the Tularosa Basin, New Mexico
Geothermal energy is considered an essential renewable resource to generate flexible electricity. Geothermal resource assessments conducted by the U.S. Geological Survey showed that the southwestern basins in the U.S. have a significant geothermal potential for meeting domestic electricity demand. Within these southwestern basins, play fairway analysis (PFA), funded by the U.S. Department of Energy’s (DOE) Geothermal Technologies Office, identified that the Tularosa Basin in New Mexico has significant geothermal potential. This short communication paper presents a machine learning (ML) methodology for curating and analyzing the PFA data from the DOE’s geothermal data repository. The proposed approach to identify potential geothermal sites in the Tularosa Basin is based on an unsupervised ML method called non-negative matrix factorization with custom k-means clustering. This methodology is available in our open-source ML framework, GeoThermalCloud (GTC). Using this GTC framework, we discover prospective geothermal locations and find key parameters defining these prospects. Our ML analysis found that these prospects are consistent with the existing Tularosa Basin’s PFA studies. This instills confidence in our GTC framework to accelerate geothermal exploration and resource development, which is generally time-consuming.

Defining the Range of Water Withdrawals That Are Forbidden and Regulated for Geothermal Energy Development and Use Projects: A Case Study of Lindian County, Northeast China
The current study reveals a deficiency in knowledge regarding the assessment of the breadth of prohibitions and restrictions on water withdrawal for the development and utilization of geothermal resource projects involving water withdrawal. To resolve this matter, this report outlines the extent of water withdrawal prohibitions and restrictions for geothermal energy development and use projects, with a particular focus on Lindian County’s medium- and low-temperature geothermal resources of the sedimentary basin type. A comprehensive consideration of geological, hydrological, and other factors was made in light of the need for global energy transformation and the benefits and drawbacks of geothermal energy. The study first divided Lindian County into 17 zones using the zoning method of dominant sign and superposition method, which was then combined with the hierarchical analysis method. The evaluation indexes were then quantitatively graded and evaluated in the 17 zones using the linear weighted sum method, and each zone’s suitability for water abstraction was ultimately determined. The limited and banned water withdrawal range of the Lindian County geothermal energy development and utilization project is defined based on the water withdrawal characteristics of the 17 subareas. The rational development of geothermal energy, the preservation of the natural environment, and the advancement of the geothermal industry in Lindian County are all greatly impacted by this study, which offers a more sophisticated methodology for the assessment of water withdrawal type projects of sedimentary basin-type medium- and low-temperature geothermal resources.

Acceleration towards clean energy with the emergence of promising signs of shallow geothermal resources in Northwestern Iran
Geoenergy refers to the energy stored or generated beneath the Earth’s surface, including geothermal heat, fuels and nuclear power. Shallow geothermal resources are an excellent energy source for various applications: they are highly efficient and cost-effective, and they can heat and cool buildings, provide hot water and even generate electricity. One promising approach to detecting geothermal energy is Geographic Information System (GIS) technology. By integrating geological surveys, geophysical and geochemical measurements and remote-sensing data into a single platform, a comprehensive view of subsurface conditions can be gained. In this study, we examined the Marand region in East Azerbaijan Province to explore shallow geothermal resources. Geochemical, geophysical, geological and remote-sensing data were integrated to assess the geothermal potential of study area. The results indicate that Marand holds viable shallow geothermal resources. Active tectonics—closely linked to kaolinite deposit formation of north Marand—have attracted both geoscientists and the Geoenergy sector to this area. The Zonouz kaolin deposits served as key indicators for locating potential geothermal reservoirs. Remote sensing and GIS methods were employed to detect geothermal anomalies: Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) imagery was analyzed to produce alteration maps. These maps indicate northern Marand area exhibits elevated thermal emissivity and strong potential for geothermal reservoirs.

Thermal Accumulation Mechanisms of Deep Geothermal Reservoirs in the Moxi Area, Sichuan Basin, SW China: Evidence from Temperature Measurements and Structural Characteristics
The Moxi area in the Sichuan Basin hosts abundant deep geothermal resources, but their thermal regime and accumulation mechanisms remain poorly understood. Using 2D/3D seismic data, drilling records, and temperature measurements (DST), we analyze deep thermal fields, reservoir–caprock systems, and structural features. The following are our key findings: (1) Heat transfer is conduction-dominated, with thermal anomalies in Late Permian–Early Cambrian strata. Four mudstone/shale caprocks and three carbonate reservoirs occur, with the Longtan Formation as the key seal. Reservoir geothermal gradients (25.05–32.55 °C/km) exceed basin averages. (2) Transtensional strike-slip faults form E-W/NE/NW networks; most terminate at the Permian Longtan Formation, with few extending into the Lower Triassic while penetrating the Archean–Lower Proterozoic basement. (3) Structural highs positively correlate with higher geothermal gradients. (4) The deep geothermal reservoirs and thermal accumulation mechanisms in the Moxi area are jointly controlled by crustal thinning, basement uplift, and structural architecture. Mantle-derived heat converges at basement uplift cores, generating localized thermal anomalies. Fault networks connect these deep heat sources, facilitating upward fluid migration. Thick Longtan Formation shale seals these rising thermal fluids, causing anomalous heating in underlying strata and concentrated thermal accumulation in reservoirs—enhanced by thermal focusing effects from uplift structures. This study establishes a theoretical framework for target selection and industrial-scale geothermal exploitation in sedimentary basins, highlighting the potential for repurposing oil/gas infrastructure.
