| 英文摘要 | Apatite fission track dating of five samples from Cenozoic volcanic strata in the Nimu District in the southern Gangdese Terrane exhibits single population grain ages with a single mean age and associated central ages ranging from 6.8 +/- 0.6 Ma to 9.7 +/- 1.2 Ma. Mean track lengths are between 12.9 +/- 1.7 mu m and 14.2 +/- 2.3 mu m with a single peak characteristic of a single thermal event. The newly documented ages coincide well with the age of high sedimentation rates in the North Tibet Basin that resulted from a 9-5 Ma compressional event. Track length modeling allows three stages to be identified in the sample cooling. The first stage (12-8 Ma) records a period of relative stability with little, if any, cooling at temperatures of 120-110 degrees C suggesting this region had low relief. The second stage (8-2 Ma) reflects rapid cooling with temperatures decreasing from similar to 110 degrees C to surface temperatures of similar to 15 degrees C. This stage can be related to far-field effects of the Himalayan collision, which probably generated the surface uplift and relief that defines the present-day Gangdese Mountains. The mean uplift rate of this period is estimated to be 1.41-0.95 mm/y with total uplift reaching similar to 5900 m. The final stage is related to surface evolution since the Pliocene. |
