通过对目前国际上诸多有关地幔氧逸度的研究结果的系统分析和总结 ,提出了地幔中自由氧对地幔物质的性质、状态及运动过程产生影响的基本作用方式 ;介绍了目前地幔氧逸度研究的主要研究手段 ,包括本征氧逸度的实验室测量、模拟氧逸度的实验室测量、地幔氧逸度计及理论计算等及其优缺点 ;定性探讨了地幔氧逸度的时空分布规律 ,获得了地幔随时间的推移变得愈来愈氧化 ,随深度的增加变得愈来愈还原 ,以及在横向上不同大地构造部位的地幔区域具有不同的氧逸度等诸多结论。
The ore-forming materials are mainly derived from the earth core constrained by deep processes and moved up to surface with multi-stages of mantle plume evolution and is contaminated with earth crust materials.
认为峪耳崖矿区成矿物质应主要来自地核,受深部过程的约束,成矿物质随地幔热柱多级演化向地表迁移,在其上升过程中,与壳源物质发生部分混染,使所测同位素数据往往表现出以深源为主、并混有少量壳源物质的特征。

因此,地幔底层既是全地幔对流的起点,又是全地幔对流的终点。
In east pacific, however, the subduction direction of the subducting plate is the same as that of the flow of the mantle, so the current dip angle of the Benioff zone will be larger than the initial dip angle.
对地幔而言 ,则是地幔相对于地壳的东向流动。
