According to the existing work foundation of the laboratory, the development trend of deposit geochemistry and the national strategic needs, the State Key Laboratory of Deposit Geochemistry takes the research of deposit geochemistry as the main line, and the specific research direction includes four aspects:
(1) Mineralization of important metallogenic belts and special metallogenic systems.Focusing on the urgently needed minerals in countries such as Au, Ag, PGE, U, Cu, Ni, Cr, Pb, Zn, etc., and focusing on the major scientific issues in the international geosciences frontier, such as the relationship between the interaction of the earth's spheres and mineralization, the relationship between continental dynamics and mineralization, the fine evolution process of mineralization, and the structure fluid matter energy chemical reaction coupling mechanism of mineralization,A new theory of continental metallogenesis based on the geological characteristics of China is established through in-depth research on the metallogenesis of important metallogenic belts and special metallogenic systems;
(2) Theoretical and experimental modeling of mineralization.Through theoretical and experimental simulation, the geochemical behavior of elements in the geological process and the physical and chemical conditions of element activation, migration and precipitation are determined to provide theoretical and experimental basis for deepening the metallogenic theory and establishing a new metallogenic model;
(3) Theories and methods for metallogenic prediction of important minerals.Taking scarce minerals and crisis mines as objects, guided by metallogenic theory, and on the basis of clarifying the space-time distribution law of mineralization, through the research on the relationship between metallogenic models and prospecting models, the similarities and differences between primary and secondary anomalies, the vertical and horizontal zoning of deposits, and the recognition of deep mineralization information under strong interference environment, the paper establishes the scarce mineralsTheory and method of metallogenic prediction in deep and peripheral areas of crisis mines;
(4) Comprehensive utilization of mineral resources and environmental effects of mine development.Taking important mines as the object, by checking the paragenetic combination law and occurrence form of elements in the deposit and the material composition of mine tailings, the study on the supergene geochemical behavior of toxic and harmful elements in the deposit, the development of the theory and technology of mine solid waste recycling, the improvement and development of the observation and analysis technology of microscopic and ultramicroscopic materials,It reveals the way of comprehensive utilization of mineral resources and the environmental effect of mine development.The overall goal of the research work is to create a new theory of mineralization, develop new theories and methods of metallogenic prediction, establish a knowledge system of comprehensive utilization of mineral resources and mine environment restoration, provide scientific basis for building a national security system of mineral resources and social sustainable development, and strive to build a national key laboratory of mineral deposit geochemistryIt will be built into a scientific research center with important international influence.[1]

The laboratory has taken practical measures to strengthen team building and personnel training, and has achieved remarkable results.During the construction period, one person from the Hundred Talents Program of the Chinese Academy of Sciences and eight young scholars with doctoral degrees will be introduced.There are 55 fixed personnel in the laboratory.Among them, there are 14 doctoral supervisors, 18 researchers, 21 associate researchers (senior engineers), 1 winner of the National Science Fund for Distinguished Young Scholars, 5 candidates of the Hundred Talents Program of the Chinese Academy of Sciences (Overseas Outstanding Talents Introduction Program), and 41 doctoral degree winners.The age and knowledge structure of the scientific and technological talent team is reasonable, and it is an excellent team full of vitality, unity and cooperation, and with sustainable innovation ability.The laboratory has 23 professional laboratories, and has basically built a group of experimental equipment matching the key research fields of the laboratory: the measurement system of major and minor components (including isotopes), the observation system of mineral structure and morphology characteristics, the metallogenic experiment and calculation simulation research system, which has built a solid technical support platform for the long-term development of key laboratories.[1]
Exchange and cooperation

edit
The laboratory attaches great importance to academic exchanges and cooperation at home and abroad.During the construction period, the laboratory hosted or participated in hosting 12 academic conferences at home and abroad.More than 20 person times of scientific and technological personnel have been sent overseas to engage in cooperative research, and more than 30 person times of overseas experts have visited and cooperated in research.40 open topics were set up, attracting outstanding scholars from domestic and foreign research institutions to come to the laboratory for guest research.
With the strong support of the Institute of Geochemistry of the Chinese Academy of Sciences, the laboratory will always focus on the national strategic goal, provide a high-level working platform for the development of new theories and methods of ore deposit geochemistry, and create a group of talents who can aim at the frontier of international science in the field of ore deposit geochemistry for innovative research,To enhance the international competitiveness of the research on the theories and methods of mineral deposit geochemistry in China, better play the important role of the theories and methods of mineral deposit geochemistry in the exploration, development and utilization of mineral resources, and provide scientific basis for ensuring the sustainable supply of national mineral resources and resource security.[1]
