概论这里所研究的热液体系是指受热的水与岩石或岩浆相互作用中的任何体系,可能有火成岩或岩浆的直接或间接参预,但并不一定包含热液一词的意义。水热溶液中REE的分布将是被溶液与岩石相之间REE的分离控制的。但是,溶液/矿物或溶液/熔体的分离系数(Partition Coefficient)不适用于大部分水热体系中的普遍条件。此外,大部分硫化物和氧化物矿物都不是REE的好寄主,所以REE的分析通常是限于非硫化物的脉石矿物。
Introduction The hydrothermal system studied here refers to any system of interaction between heated water and rock or magma, with the possible direct or indirect involvement of igneous or magmatic rocks, but does not necessarily imply the meaning of the word hydrothermal. The distribution of REE in a hydrothermal solution will be controlled by the separation of the REE between the solution and the rock phase. However, the solution / mineral or solution / melt partition coefficient (Partition Coefficient) does not apply to most conditions in the hydrothermal system. In addition, most of the sulfide and oxide minerals are not good hosts for REE, so REE analysis is usually limited to non-sulfide gangue minerals.
