| Abstract: | The paper firstly introduces the development of mantle isotopic
geochemistry and summarizes the achievements of applying Sr Nd Hf Pb,Os,He Ar and He
isotopes to tracing rock sources and distinguishing their geneses.Recent major studies
show that the isotopic information is very important and effective to investigate mantle
derived rocks.Then,some main methods determining mantle compositions and the
significance of globally uniform ratios such as Nb/U,Y/Ho and Ce/Pb are presented.At
the same time,it is pointed out that the backward of analytical technique and the
nonbreakthrough of fundamental theories affect seriously the application and development
of isotopes and minor elements to mantle researches. |
