Understanding nature and acquiring knowledge about Earth’s natural attributes have always been the primal driving force behind scientific research. They reflect humanity’s need to make better use of nature, live in harmony with it, and are also topics of public interest and science communication. “ Chemical Earth ” The Grand Plan is a global, internationally collaborative initiative involving scientists from around the world aimed at acquiring knowledge about Earth’s natural attributes. To date, humanity has discovered in nature... 92 The natural elements that make up the Earth—the planet on which humanity survives—are precisely these. 92 composed of natural elements and their radioactive derivatives. Humans live in... 92 In the Earth's surface environment, which consists of various elements, interactions and mutual influences with the Earth are constantly occurring. Therefore, understanding the distribution patterns of Earth’s own elements is not only a concern for scientists but also a matter of public interest. Completing this task can provide essential data and information for studying and addressing issues related to Earth’s evolution, as well as resource and environmental challenges. Geochemical mapping is an effective approach for achieving this goal.

　　Geochemical mapping is the primary focus of exploration geochemistry. Geochemistry is a fundamental, broad-based discipline, and applied geochemistry is a branch of geochemistry itself. Among the various branches of applied geochemistry, exploration geochemistry stands out as the most important, with the goal of understanding the distribution patterns of chemical elements at global or regional scales.

　　proposed by Academician Xie Xuejin, a world-renowned geochemist “ Regional Geochemical Survey National Scanning Program RGNR ) ” is one of China’s largest scientific research programs, and this work began with 1978 Year, newly discovered mineral deposits nationwide 80% All of the above were discovered through clues provided by this program. Although this program was not the world’s earliest geochemical mapping initiative, it received strong government support, boasted the most thorough theoretical and technical preparation, the most systematic organization, the largest number of participants, the greatest scale, the longest duration, and the richest set of achievements. The program was implemented until the last century. 90 Over the years, China has already established a significant presence in the global field of geochemical mapping. This work not only plays a crucial role in mineral resource exploration but also helps address a range of environmental and human health issues. In practice, the theories and methodological techniques of geochemical mapping have continued to evolve and have gradually gained acceptance among international peers; some of these techniques have even been adopted as internationally recognized standards.

　　From 1993 Starting from that year, Chinese geochemists led by Xie Xuejin began to take the lead in global geochemical mapping, initiating and participating in... IGCP259/360 Global Geochemical Mapping Comparison Project. 1993 In that year, China hosted the 13th Annual Meeting of the International Association of Geochemists, marking the official entry of China’s geochemical mapping onto the global stage. 1996 In that year, taking the opportunity of hosting the International Geological Congress, China held its first international training course on geochemical mapping, marking the official entry of China’s theories, methodologies, and expertise onto the global stage and placing it among the world’s leading nations. As of... 2015 By the end of the year, China had held training courses on geochemical mapping in various formats. 28 Period, training worldwide 60 Multiple countries 600 Numerous individuals—excluding those trained through the geochemical mapping collaboration project—have effectively shared China’s theoretical and methodological approaches to geochemical mapping, as well as the operational model for implementing the national geochemical mapping program. At the same time, they have forged friendships with international experts in geochemical mapping and established an extensive international network for geochemical mapping cooperation.

　　To date, China has established relations with Brazil, Colombia, Argentina, Kazakhstan, Mongolia, Tajikistan, Kyrgyzstan, Uzbekistan, Pakistan, Laos, Indonesia, the Philippines, Papua New Guinea, Peru, Guyana, Zimbabwe, Ethiopia, Zambia, South Africa, Sudan, Eritrea, Madagascar, Chad, Morocco, and Liberia. 25 A number of national geological survey agencies are collaborating on and have already implemented geochemical mapping projects. They are also cooperating with the European Geological Surveys on global geochemical reference frameworks. Currently, they are exploring opportunities to collaborate with countries including Iran, Serbia, Turkey, Mexico, Cambodia, Nigeria, Mali, and Uganda on the implementation of geochemical mapping projects.

　　In addition to geochemical mapping, the collaboration also includes technical exchanges and personnel training, truly achieving... “ Teach a person to fish. ” Enhance the capacity of partner countries to conduct geochemical mapping independently, and even, through collaboration, build a team within those partner countries capable of carrying out their own geochemical mapping efforts.

　　The cooperation models are as follows: 4 Species:

　　The Colombian Model: China is responsible for technical training and developing the field sampling work plan. Colombian geochemists will collect the samples, and Chinese laboratories will handle the analysis and data sharing.

　　The Mongolian Model: Chinese geochemists traveled to Mongolia to provide on-site training for the country’s geochemists and jointly carried out the first phase of geochemical field sampling. The main fieldwork was conducted by Mongolian geochemists, and the samples were sent to Chinese laboratories for analysis. 71 One indicator.

　　The Zimbabwe Model: The entire geochemical mapping project was led and completed by Chinese geochemists, with the participation of some personnel from the Zimbabwe Geological Survey. Samples were analyzed in Chinese laboratories.

　　The Guyana Model: China provides only technical assistance, sending two geochemists to Guyana to guide the country’s geochemical mapping efforts and help establish a national geochemical database.

　　In the collaboration, significant achievements have been made: First, a batch of... 39 seed ~76 First, geochemical maps and data on various elements have been systematically obtained for the first time by several countries, including Zimbabwe and Sudan. Leveraging the clues provided by these maps and data, dozens of potential mineral deposits—ranging from super-large to large-scale—have been preliminarily identified, attracting mining investments and boosting local economic development. Second, the capacity of partner countries to conduct geochemical mapping has been enhanced, and talent and teams specializing in geochemical mapping have been cultivated. Third, the global geochemical mapping database and content have been enriched, providing foundational data for better understanding the global-scale distribution of elemental geochemistry and gaining insights into the natural geochemical properties of elements from an elemental perspective. Fourth, China’s decades of accumulated experience and advanced methodologies in geochemical mapping have been shared with the international community, enhancing China’s global influence and demonstrating its responsibility as a major country—a concrete practice of engaging in global governance. Fifth, a solid foundation has been laid for establishing an international center for global-scale geochemical research in China, and this will enable China to take the lead in implementing... “ Chemical Earth ” The international big science initiative has provided the necessary support. Sixth, this represents a concrete practice in building a world-class geological survey bureau. By collaborating with these countries to implement projects, we not only enhance technological exchanges but also deepen mutual understanding, showcasing the strength of China’s Geological Survey Bureau and earning widespread recognition.

　　China Geological Survey “ The Father of Geochemical Mapping ” Academician Xie Xuejin has been awarded the Gold Medal by the International Association of Geochemists. In addition, China also has... 20 People obtain 3 Medals awarded by the country, National Gold Awards / Silver award, etc.
