| 摘 要： | 由于Ｒｅ，Ｏｓ独特的地球化学性质，Ｒｅ－Ｏｓ同位素体系可以用来确定特定矿床的形成年龄，特别为金属矿床形成时代的研究开辟了新的途径，同时，由于Ｒｅ，Ｏｓ的元素相容性不同，导致不同地球化学储源库具有不同的Ｏｓ同位素特征，特别是地壳和地幔具有截然不同的Ｏｓ同位素特征，据此可以用来讨论不同类型矿产质和岩浆的来源。

| Abstract: | Re-Os isotopic system is a widely used method in earth science researches since 1990's,the u-nique characteristics of Re-Os isotope make it possible to determine the age of some special kinds of ore de-posits,especially the age of metallic ore deposit. At the same time,the different incompatibilities of Re and Os result in the variation of diffcrent geochemical reservoirs,for example,the evident Os isotopic difference between the crust and the mantle,which can be used to discussing the origin of different ore deposits and magmas. The studies show that the lithosphcre plays an important role in the generation of continental flood basalt(CFB),and the mantle plume is related to the evolution of core-mantle evolution. |
