This paper aims to discuss the geochemical characteristics and genesis of Qinglongshan fluorite de-posit in Quannan County of Jiangxi Province.Rare earth elements of the ore and surrounding rock samples are analyzed for Qinglongshan fluorite deposit.The average content∑REE of Qinglongshan fluorite ores is 88.186 × 10-6,δEu is 0.23-0.61 and 8Ce is 0.78-0.91.The average content ∑ REE of the surrounding rocks is 184.52× 10-6,δEu is 0.31-0.69 and 8Ce is 0.85-1.REE distribution patterns of fluorite ores and sur-rounding rocks have similarity and synchronization,showing a right-leaning type of relative enrichment of light rare earth elements with moderate loss of Eu and weak loss of Ce.The rare earth geochemical study re-sult of ore and surrounding rock indicates that there are at least two metallogenic stages in the fluorite depos-it,which are magmatic hydrothermal mineralization.The mineralization environment is a stable and relative-ly reducing condition,and the temperature of the ore-forming fluid is about 200℃.
