| 摘 要： | 本文用ＩＣＰ－ＭＳ测定了辽宁四道沟金矿矿脉中石英及其中流体包裹体中的稀土元素含量，发现石英的稀土元素配分模式类似于其中流体包裹体的稀土元素配分模式，推断石英中的稀土元素主要赋存于注流体包裹体中，流体包裹体中的稀土元素了石英的稀土元素配分模式，原生包裹中的流体是和石英同源的，其稀土元素指示的是石英形成过程中流体的信息。而次生包裹体中的流体是石英形成后的流体活动产物，其稀土元素指示的是后期流体活动的信

| Abstract: | The rare earth elements in quartz and fluid inclusions from the Sidaogou Gold Deposit, Liaoning were determined by Inductively Coupled Plasma Mass Spectrometry (ICP MS). The result shows that the REE pattern of quartz is similar to that of fluid inclusions. The REE in quartz are concentrated in fluid inclusions, and the REE pattern of the fluid inclusions shapes the REE pattern of the quartz in which it occurs. The primary inclusions are affinal to quartz, and the characteristics of REE in them should represent the characteristics of quartz forming fluid. Whereas the formation of the secondary inclusions is later than the crystallizing of quartz, and the REE in them will give out the information of late stage hydrothermal solution. Careful examination of fluid inclusion in gold bearing quartz vein of Sidaogou gold deposit reveals that the primary pseudo secondary inclusions in quartz vein are dominant, therefore, the REE parttern of gold bearing quartz veins represents the REE pattern of ore forming fluid of Sidaogou gold deposit. |
