Lithium is an important rare metal in the field of new energy,which has been widely recognized and applied in China. As a result,demand is growing. This is more and more demanding for prospecting in the geologi-cal and mineral industry. The Hunan-Jiangxi region is located at the junction of the Yangzi Ancient Plate and the Cathaysian Ancient Plate,and is an important distribution area of lithium resources. The type of mineral deposits is mainly altered granite type,and the mineralization ages are mostly Yanshan period. The distribution of lithium deposits is related to tectonic-volcanic activities. The highly evolved granite at the top and edges often undergoes greisenization,albitization,etc. The higher the degree of evolution and differentiation,the more concentrated the rare metals such as lithium are. By sorting out the lithium and rare metal deposits in the region,the geological characteristics of the deposit and the metallogenic regularity have been summarized,and six deposit metallogenic series have been divided. It has a certain guiding significance for the next phase of mining in the area.
