| 摘 要： | 据各类样品的REE组成，研究了三个矿床矿石，恂变围岩及其原岩REE地球化学特征，计算出近似的成矿流体REE成分，讨论了REED 成矿（蚀变）过程中的地球化学行为，结合其他地质地球化学特征认为成矿物质主体是来源于下部的富金属流体，蚀变围岩的REE模式可作为寻找盲矿标志。

| Abstract: | REE geochemical characteristics of ores, altered rocks and related unaltered rocks of three ore deposits have been studied. REE compositions of similar ore fluids have been computed and REE geochemical action have been discussed by REE patterns in the process of mineralization and alteration. In conjunction with other geological and geochemical data, it is considered that the main part of ore_forming material was derived mainly from deep position of the earths crust. REE patterns characterized of altered rocks can be regarded as the sign of looking for blind ore body |
