| 摘 要： | 东秦岭造山带核部杂岩，在高温高压环境下曾出现大量流体，由溶解作用产生的流体在变形分解带内运移，形成古水热循环系统，该水热系统使岩石中如铀等大离子富集成矿，水岩相互作用造成秦岭杂岩中稀土元素四重分布效应．

| Abstract: | A lot of fluid was formed in the core complex of the eastern Qinling orogenic belt under the high temperature and pressure. The fluid caused by the dissolution was transfered in the deformation partitioning belts.As a result, an old hydrothermal circulation system was developed, large ions such as uranium were then enriched in such kind of system and relative uranium deposits are formed in Qinling complex. The rare earth elements distribution of the Qinling complex shows a typical tetradic effect, which is caused by the interaction of water and complex. |
