1.
Based on research results at home and abroad, this paper studies the geochemical characteristics of trace elements of mantle domains such as DMM, HIMU, EM1 and EM2 defined by isotopic geochemistry, and discusses the genesis of those end-member components.
结合国内外研究现状，对利用同位素地球化学所确定的地幔端元组分DMM、HIMU、EM1和EM2在微量元素地球化学上的特征进行了综述，并对其成因进行了讨论。

补充资料：地幔
| 地幔 earth mantle 地壳和地核之间的中间层。平均厚度为2800余千米 。1914 年 B. 古登堡根据地震波走时测定地核的深度为2900千米，比现代精密测量的结果只差15千米。因此，地核-地幔边界又称古登堡不连续面。 见地球内部构造。 |
