In recent years, the project of Strategic Emerging Industry Mineral Geological Survey, organized and implemented by China Geological Survey, has achieved a series of new advancements in the new round of mineral exploration for “five rare” minerals. After the compilation of the Mineral Geological Atlas of China and potential assessments of key minerals, 88 volumes of the atlas have been officially published focusing on the phased objectives and tasks. Among them, 19 national-level mineral group atlases covering strategic minerals such as fluorite, nickel ore, and antimony ore, as well as 10 provincial-level atlases, have been completed and published. A total of over 200 atlas manuscripts, encompassing “books, maps, databases, and popularization,” have undergone review and acceptance, achieving full coverage of mineral types, mineral localities, and metallogenic belts nationwide. A series of important mineral concentrations, prospective areas, and target areas have been identified, providing basis for the deployment of the new round of strategic action for breakthroughs in mineral exploration. From the perspective of the development of strategic emerging industries, pilot demonstrations for mineral exploration have been carried out for minerals and working areas with greater difficulty, resulting in breakthroughs in the mineral exploration for Jiada large-scale lithium resource base in Aba Prefecture of Sichuan Province, and facilitating the auction of exploration rights. Besides, breakthroughs have also been made in mineral exploration for rare earth deposits in Longjiagou on the southern periphery and Huandangou on the northern periphery of Maoniuping in Liangshan Prefecture of Sichuan Province, contributing to the increase in reserves and production at Maoniuping national-level large-scale resource base. Furthermore, a number of new mineral exploration achievements have been made, including lithium deposits in Altun Mountains of Xinjiang, placer zirconium and hafnium deposits in South China, beryllium-niobium-tantalum deposits on the northern edge of Mufu Mountains, and boron deposits in Tianshan Mountains, laying the foundation for the implementation of the new round of strategic action for breakthroughs in mineral exploration. Significant technological innovations have been achieved in metallogenic theory, metallogenic regularities, deep exploration of concealed ore bodies, green survey and evaluation, and other aspects. Those innovations have shown their value in promotion and application after practice, providing theoretical and technical support for the implementation of the new round of strategic action for breakthroughs in mineral exploration.

Maoniuping deposit in Sichuan Province stands as the world's third-largest rare earth deposit, following Baiyunebo and Mountain Pass, which has great potential in finding alternative resources and ensuring Chinese rare resource advantage. Recently, second-phase exploration breakthrough has been achieved in the southern and northern peripheries of Maoniuping deposit. A concealed thick and rich rare earth-molybdenum orebody was discovered in the northern periphery around Huandangou, through comprehensive survey and evaluation work in the peripheries of Maoniuping deposit, and verified by drilling and the average total rare earth oxide content in borehole ZK4501 reaches 2%. Fifty layers of rare earth orebodies have been explored in the southern periphery, including bastnasite-(Ce)-aegirine-fluorite-barite vein type, bastnasite-(Ce)-fluorite-barite-calcite vein type, bastnasite-(Ce)-aegirine-barite vein type, and bastnasite-(Ce)-fluorite-calcite vein type. The discovery of these new orebodies with high grade and easy mining is another significant breakthrough in rare earth mineral exploration since the implementation of the new round of strategic action for breakthrough in praspecting which is of great significance for enhancing the resource security capabilities of China's second-largest rare earth resource base.

DOI: 10.19388/j.zgdzdc.2024.338
In the drilling construction of deep hole geological core, the traditional drilling tool of same-diameter wireline corer has technical problems of inefficient drilling, narrow tubular annulus, and high defective rate under complex geological environment, restricting the deep hole drilling development. By optimizing the combination of drilling pipe and drilling bit, the authors in this research developed cross-diameter wireline corer drilling tool, and systematically analyzed the mechanical characteristics. The stress distribution and torsional stiffness under different diameter combinations were identified through mechanical modeling and experimental verification, and drilling tool optimization scheme was constructed. The engineering practices of a rare earth mine exploration, shale gas exploration in Sichuan Basin and Pu'er geothermal well in Yunnan Province shows that the cross-diameter drilling tool could bear high torque of 8 000 N·m and drilling pressure of 200 kN, with the maximum drilling depth of 1 500 m. And this cross-diameter drilling tool show good stability under high temperature of 200 ℃ and high pressure of 30 MPa, with the drilling efficiency rising 35% and the core acquisition rate reaching 98%. The research results provide new solutions for technical problems during deep hole geological core drilling, and important practice guidance for improving deep geological exploration efficiency and core collection quality.

ZHANG Jiajia, MIU Xuhuang, LI Xiaohui, YE Shengfei
DOI: 10.19388/j.zgdzdc.2024.316
Fengyang Jiangshan gold mine is the largest gold deposit in eastern Anhui Province. In recent years, multiple exploration projects have been implemented in its surrounding areas without any good prospecting results. Through the use of geophysical methods, such as gravity scanning, gravity magnetic profiling, and audio magnetotelluric depth sounding (AMT), the authors summarized the characteristics of regional gravity and magnetic fields and considered that there are hidden tectonic magmatic rocks in the study area. The AMT low resistance anomaly zone is believed to be corresponded well with the gold bearing interlayer fracture zone, after the analysis of the geophysical characteristics of known mineral deposits. Besides, Lutang fault is the main ore controlling structure in the area, on basis of the summary and analysis of the geological conditions and laws of mineralization. Through gravity inversion, it is believed that the top interface burial depth of hidden rock mass in the deep part is mostly around 1 100 m. The 3D mineralization prediction research in Jiangshan of Fengyang area was conducted by 3D mineralization quantitative prediction method system with 4 steps, and 5 prospecting target areas were identified, providing the basis for the exploration work in the future.

HUANG Jiazhong, WU Zhichao, WANG Bingjun, BAI Pingyan, ZENG Liang, LI Jinwang
DOI: 10.19388/j.zgdzdc.2024.234
Jin Mountain in Mojiang is located within the mineralization belt of the Ailao Mountains, and it is a significant gold-nickel deposit in Southwest China. To assess the prospecting potential in peripheral Jin Mountain of Mojiang, the authors performed soil geochemical analyses in Guanyin Mountain area, focusing on the distribution characteristics of elements such as arsenic (As), gold (Au), cobalt (Co), copper (Cu), nickel (Ni), antimony (Sb), vanadium (V), tungsten (W), and titanium (Ti) within the soil matrix. Based on the metallogenic geological background in the area, the authors summarized the mineralization patterns of these elements and delineated 6 synthetic anomalies, using cluster analysis, hot and cold spot analysis, and factor analysis. These findings reveal a relative enrichment of Sb, As, Au, Cu, V, and Ni in the area, with particularly high concentrations of Au and Ni, indicating a pronounced degree of enrichment and potential for localized mineralization. Notably, Au exhibits a weaker correlation with other elements, suggesting a complex and multi-stage mineralization process. Conversely, Co and Ni frequently occurred in proximity to the contact zones of rock bodies, and are closely associated with ultramafic rock formations.It is indicated that Guanyin Mountain area has good prospecting potential, and gold mine should be primarily targeted, and arsenic-antimony and cobalt-nickel deposits in the second place. This research could provide the prospecting direction for the new round of strategic action for breakthrough in prospecting in this region.

SHU Xiangqing, GAO Baolong, YANG Yuzhen, ZOU Xuan, YUAN Xiong, MIN Dan
DOI: 10.19388/j.zgdzdc.2024.135
The tectonic framework in Hala-alate Mountain area of Xinjiang at the Late Carboniferous is island arc developed under trench-arc-basin system, and the Upper Carboniferous Tailegula Formation black shale is considered to be a product of deep-water deposition in the trench and forearc basin during the period of island arc effect being relatively weakened, but with a lack of geochemical evidence. Trench exploration and sampling analysis were conducted on the black shales of Tailegula Formation in the study area. The results show that the black shale of Tailegula Formation in the study area is rich in MgO and Na2O, poor in TiO2, Al2O3, Fe2O3 and CaO2, and moderate in SiO2. The large ion lithophile element is relatively poor, and light rare earth element is relatively rich. The heavy rare earth element is relatively loss, and the δEu has negative anomaly, indicating similar distribution pattern with rare earth element in the upper crust. The tectonic setting of Tailegula Formation black shale in Hala-alate Mountain is mainly the continental island arc. The source rock belongs to intermediate to acid and felsic provenance, and it mainly originates from upper continental crust. The source region is probably Early Paleozoic trench-arc of Tarbagatay-Narmande and Late Paleozoic island arc of Xiemisitai-Dongquan in the north. This study could provide some references for the provenance analysis of the giant thick shales in Hala-alate Mountain area.

DOI: 10.19388/j.zgdzdc.2024.110
Yuxian Basin has rich geothermal resources and complex geological structures. The study on the hydrochemistry, isotope and circulation characteristics of geothermal fluids controlled by geological structures can further promote the development and utilization of geothermal resources and geothermal hot spring health care industry around the capital city. By combining groundwater and atmospheric precipitation, and using multivariate statistics, correlation and characteristic coefficient analysis, the authors studied the geothermal fluid in Yuxian Basin using Piper triplex diagram and Na-K-Mg triangle diagram. The results are as follows. ① The cations in geothermal fluid are mainly Na+, Ca2+ and Mg2+, and the anions are mainly HCO3- and SO42-. Ca2+, Mg2+ and HCO3- are mainly derived from the dissolution of carbonate minerals. ② A cation alternat adsorption occurred in geothermal fluid, with the action direction of K+, Na+ into the liquid phase, and Ca2+, Mg2+ into the solid phase. Na+ and Ca2+, Mg2+ are in a state of mutual inhibition. ③ The thermal reservoir formation is poorly sealed, the concentration degree and metamorphism degree of geothermal fluid are low, indicating a significant affection by infiltration water and shallow surface oxidation. The main source of geothermal fluid recharge is atmospheric precipitation, and the runoff path is short with fast water cycle. ④ The heat storage temperature was 37.32~57.36 ℃, the maximum circulating depth of heat storage in Wumishan Formation of Jixian System was 1 715~2 640 m, and the maximum circulating depth of the heat storage in Gaoyuzhuang Formation of Jixian System was 3 291~3 337 m, with the average value of 3 314 m. The interaction between groundwater and rock under geological structure was revealed, which could provide certain guidance in studying the hydrochemical evolution and dynamic characteristics of geothermal fluid in this area.

YANG Feng, LU Ye, LI Shiying, LIN Zhenwen, ZHENG Siqi, LUO Junchao, GUO Feng
DOI: 10.19388/j.zgdzdc.2024.164
In order to reveal the geochemical characteristics of trace elements in marine surface sediments in Guangdong-Macao in-depth cooperation zone in Hengqin, the authors analyzed the grain size of surface sediments and 14 trace elements. The distribution, source and control factors of trace elements in surface sediments were discussed, combined with element correlation analysis and factor analysis, and the potential ecological risk of heavy metal elements were evaluated. The results are as follows. ① There are five types of surface sediments in the cooperation zone, including sand (S), muddy sand (mS), sandy silt (sZ), silt (Z) and mud (M). ② The content of Zn, V, Cr and Ba in surface sediments of the cooperation zone is relatively high, with an average of more than 100×10-6. The content of Ba is the highest with an average of 431.13×10-6, and content of Cd is the lowest with an average of 0.73×10-6. The average content of other elements is between 15.95×10-6 to 83.03×10-6. The surface sediments in the cooperation zone are enriched in the heavy metals, such as Cd, Pb, Zn, As, and Cu, compared with the sediments in Pearl River. ③ Natural weathering of land rock and artificial discharge are the main source of the trace elements in surface sediments of the cooperation zone. The content variation of Sc, Co, Ni and Ga are mainly controlled by sedimentary hydrodynamic environment, while the content variation of Ba and Cd are controlled by human activities. And the contents variation of Pb and Zn are influenced by both natural source and human activities. ④ The average potential ecological risk index of heavy metals in surface sediments in the cooperation zone is 140.79, in generally serious state. This is mainly caused by Cd, indicating the monitoring of Cd should be strengthened. The research results could provide scientific basis for the sustainable development, environmental protection and governance of Guangdong-Macao in-depth cooperation zone in Hengqin.

MIAO Yuanliang, ZHANG Shukun, MENG Chao
DOI: 10.19388/j.zgdzdc.2024.148
In order to accurately grasp the deformation and development laws of landslides in the accumulation lager on the bank of the Three Gorges Reservoir area, the authors conducted a comprehensive study on landslide deformation trends using the rescaled range method, grey model and optimized generalized regression neural network, based on the landslide deformation monitoring data. The research results show that the Hurst exponent of each monitoring point is greater than 0.5 in the landslide deformation trend discrimination results, indicating a continuous increasing trend of landslide deformation. In the deformation prediction results, with the continuous optimization and combination processing of the GM (1,1)-SFLA GRNN model, the prediction accuracy has been significantly improved, indicating that the model construction process is reasonable. Besides, its prediction shows that landslide deformation will continue to increase. The average relative error of the obtained prediction results is between 1.76% and 1.82%, and the training time is between 52.21 ms and 57.23 ms, which has a better prediction effect. Then, BP neural network and support vector machine were introduced for analogical prediction. The results show that the GM (1,1)-SFRA-GRNN model has relatively higher prediction accuracy and faster training speed compared to BP neural network and support vector machine. Comparing the results of landslide deformation trend discrimination and the results of deformation prediction, the authors found that landslide deformation will continue to increase without convergence trend. The necessity of landslide prevention and control is significant, and the rationality of the two analysis methods is mutually supported, providing certain theoretical support for landslide prevention and control.

WANG Shibao, LI Chenglong, WANG Na
DOI: 10.19388/j.zgdzdc.2024.114
Suide County is located in the hinterland of the Loess Plateau in northern Shaanxi, with great loess fluctuation and intense human activity, which leads to the development of collapse and landslide disasters and seriously threatens the safety of local people's lives and properties. Suide County was taken as the study area to identify the prone and dangerous sections of loess collapse and landslide using high-precision Digital Elevation Model (DEM) (2 m×2 m) and high-resolution remote sensing images (0.2 m). A comprehensive identification and verification of loess collapse and landslide was conducted in the study area, and an information quantity model was used to construct the evaluation of loess collapse and landslide susceptibility based on the verified hidden danger point data. The results showed that 3 529 dangerous sections with threatening objects were identified based on DEM and remote sensing technology, and 3 116 hidden danger points of loess collapse and landslide were confirmed through field verification, with an accuracy rate of 88.30%. The study area has an extremely high susceptible area of 131.32 km2, a high susceptible area of 275.35 km2, and a moderately susceptible area of 335.74 km2, those three mainly distributed in steep slopes, high slopes, and slopes with strong human engineering activities in sheets along the loess ridge and hill area. Besides, 75.80% of the hidden dangers of loess collapse and landslide is distributed in extremely high, high, and medium susceptible areas, and the susceptibility evaluation results are reliable. The research results have further improved the precise identification ability of loess collapse and landslide in Suide County, and the evaluation results could provide the basis for disaster prevention and reduction work and national spatial planning in Suide County, which have certain reference significance for the precise identification of loess collapse and landslide in other similar geological environment areas.

100 Risk assessment of geological hazards under different plotting scales: A case study of Huangxikou Town in Hunan Province
LIN Gaocong, LIU Huan, WANG Honglei, PAN Shuhua
DOI: 10.19388/j.zgdzdc.2024.141
In order to explore the differences and applicability of geological disaster risk assessment models and methods under different plotting scales, the authors took Huangxikou Town in Hunan Province as the study area and selected 8 evaluation indicators, such as engineering geological petrofabric and slope structure, to assess the geological disaster risk under 1∶50,000 scale with grid unit using information model, on the basis of disaster geological survey map unit. The results show that the low, medium, high, and extremely high risk areas in the study region account for 32.0%, 24.6%, 38.0%, and 5.4% respectively of the total area. One hundred and sixty-one slope units were divided using hydrological methods and manual intervention methods, and 17 indicators and 30 factors under the categories of the possibility, intensity, category and quantity of disaster-bearing bodies and vulnerability of geological disasters, were selected to construct an analytic hierarchy process grading model. The 1∶10,000 scale risk assessment of geological disasters with slope as the basic unit was carried out, and 84 low-risk slopes, 49 medium-risk slopes, 24 high-risk slopes, and 4 extremely high-risk slopes were identified within the key study area. Due to the influence of survey accuracy and evaluation methods, the assessment results of the two model methods for the same location are not entirely consistent. Therefore, it is advisable to select an appropriate evaluation method based on survey accuracy and research depth. For geological disaster risk assessments in areas under small and medium scales, the information quantity evaluation model based on quantitative calculations using mathematical statistics is recommended, with characteristics of simple, easy to promote, and efficient in modeling, making it suitable for regional promotion. For geological disaster risk assessments in key areas under large scales, the multi-indicator scoring and grading evaluation model on the basis of hierarchical analysis is recommended based on detailed slope unit survey results. These evaluation indicators are detailed and easy to understand, allowing for risk assessments of individual slope units, which is suitable for slope management and dynamic updates of slope risks. This study results could provide some references for the selection and application of geological disaster risk evaluation methods under different scales.

ZHANG Xunxun, ZHAO Yanggang, YANG Bin, WU Shuying, DUAN Yanghai, LIU Yu
DOI: 10.19388/j.zgdzdc.2024.170
Geladandong glacier complex is the source of Tuotuo River, the primary source of Yangtze River. It is located in the Tanggula Mountains, which is in the remote interior of Tibet Plateau. The processes and causes of glacier area change are crucial for the sustainable use of water resources and the functioning of the water cycle in the headwater ecosystem of Yangtze River. The random forest method was employed to carry out the interpretation of glacier remote sensing images, and topographic and climatic data were integrated to investigate the underlying drivers of glacier area change. The results are as follows. ① The random forest method is particularly suitable for the automatic interpretation of a large number of consecutive remote sensing images, after the comparative analysis of 7 most commonly used automatic computerized classification methods and the evaluation of their accuracy. ② From 1999 to 2022, the glacier area in the study area exhibited a wavy decreasing trend, with a total decrease of 64.25 km2, representing a 10.22% reduction and a decreasing trend of 2.94 km2/a. ③ The glacier terminus in the study area exhibits a relatively smooth and regular morphology, with a distinct single peak and symmetrical outline. In contrast, the glacier tongue terminus displays a more irregular morphology, with a variable edge and a shape that is evidently influenced by topographic factors. ④ The change of glacier area is significantly influenced by elevation and slope direction. Among climatic factors, temperature is the primary driver of glacier change, exhibiting a negative correlation. This research could provide the scientific basis and data supporting for glacier change characteristics and sustainable use of water resources in the primary source area of Yangtze River.
