| 中文摘要: |
| 锂作为目前新能源领域极为重要的稀有金属，受到广泛的重视和应用。随之而来，其需求越来越大，这对于地矿行业的找矿工作要求越来越高。湘赣地区地处扬子古板块和华夏古板块的交接部位，为锂资源重要分布区，矿床类型以蚀变花岗岩型为主，成矿时代多为燕山期，锂矿床的分布与构造-岩浆岩活动有关，高度演化的花岗岩，顶部和边部通常发生云英岩化、钠长石化等，演化分异程度越高，锂等稀有金属越富集。本文通过对区内锂稀有金属矿矿床的梳理，总结了锂矿床的地质特征和成矿规律，划分了6个矿床成矿系列，对区内下一步找矿具有一定的指导意义。 |
| 英文摘要: |
| 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 geological 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. |
