| Abstract: | The studies on dating of 40Ar-39Ar showed that the dating results were 69.2 Ma, 1.00 Ma, 0.37 Ma and 44 Ma for the volcanic rocks at Tongtianqiao, Ashikule-Alukekule and Bangdacuo respectively. Based on them as well as other data, the time of the volcanic action and space-time evolution of the Cenozoic volcanism in northern Tibet were discussed. |
