摘　　要：已证实,粤北诸广山岩体南部某铀矿区内矿体多以隐伏矿体存在,其深部铀矿找矿前景巨大。由于稀土元素与铀矿体存在伴生关系,对地气稀土元素与岩石稀土元素的分布规律进行探讨。结果表明:地气测量的稀土配分模式与岩石稀土配分模式和δEu以及LREE/HREE比值基本一致;地气元素中Ce的变化规律与岩石本身的Ce变化规律类似,随着地层由老到新,δCe由大于1逐渐变成小于1;地气稀土元素与岩石稀土元素相似却不相同的性质是由地气纳米颗粒的不同元素的不同迁出率引起的。South area of Zhuguangshan in north Guangdong province, there are a large of uranium deposits have been found. Most of ore body exist in the form of concealed ore body. Due to rare earth elements associated with uranium, Geo-gas method REE distribution and rare earth element distribution of rock were compared. Results indicate that ： REE patterns to geo-gas measurement is consistent with the rock REE distribution and δEu and LREE/ HREE ratio; There are similarities between geo-gas measurement and rock in Ce regularities of distribution, with the formation from the old to the new, The value of δCe Greater than 1 becomes into a less than 1 smaller by the gradually ; geo-gas rare earth elements and rare earth elements in rocks of similar nature are not the same emigration rates of different elements to different gas nanoparticles caused.
