China's scientific research team took the lead in establishing the first mineral supergroup classification and naming scheme, which was approved
Recently, the naming scheme of strontium carbonate supergroup established by an international research team led by Academician Hou Zengqian's team has been officially approved by the International Mineralogical Association Committee on New Mineral Nomenclature and Classification (IMA-CNMNC). "This is the first mineral supergroup classification and nomenclature system established by a scientific research team in China. ”Gu Xiangping, vice chairman of China New Minerals and Mineral Nomenclature Professional Committee, introduced. The strontium carbonate supergroup is a hydrous rare earth carbonate mineral. Due to its unique physical and chemical properties, rare earth is widely used in new energy, new materials, energy conservation and environmental protection, aerospace and electronic information and other fields, and is an indispensable and important element in modern industry.

International peers believe that the establishment of the strontium carbium supergroup not only clarifies the chemical formula, classification boundary and nomenclature principle of the mineral supergroup, conveys important mineral chemical information for crystallographers and mineralogists, but also provides a new reference for the study of the migration and precipitation mechanism of rare earth elements in alkaline rocks and carbonate rocks. Wang Yanjuan, the first author of the nomenclature scheme and a doctoral student at China University of Geosciences (Beijing), introduced that the discovery of new minerals and the classification and naming of minerals are important basic research in the field of geology, and the scientific classification and naming scheme can provide international standards and specifications for human understanding of complex mineral systems and how to classify minerals. Up to now, there are 34 mineral superfamilies officially approved and recognized by IMA-CNMNC, and 31 mineral families have been independently graded. "For a long time, the research work of formulating the classification and naming scheme of mineral supergroup has been monopolized by Western countries, and the establishment of the strontium cerium carbonate superfamily has improved the basic research level and international influence of mineralogy in China. Wang Yanjuan said. **Xinhua News Agency
