| Abstract: | Existing four tectonic events for early evolution of the Altun structural belt,the age is separat-ly 2790 2590, 1883 1704,575 and 470 420Ma. This conclution results from U-Pb,Sm-Nd,Rb-Sr,(40)Ar/(39)Ar,(18)O/(16)O iSotopic system studies. Four data respectively represent basement forma-tion,cratonization,accretion and collision of the plate located Altun mountain in. |
