| Abstract: | The applications of the Re\|Os isotope system to geochronology and geological tracing are introduced, based on a summary of the main papers published since the 1960's on geoscience. The principle of Re\|Os dating, experimental techniques and problems in geochronology are clearly interpreted. The abundance and distribution and the evolution characteristics of the Re\|Os system in different reservoirs including continental crust, meteorites and mantle are discussed in detail. Recent developments in research on the Re\|Os isotope system, as a tracer of the mantle geochemistry and crust\|mantle evolution and the extraterrestrial impact events, are also introduced in the present paper. |
