英文摘要	Nanmulin district is, located at the south of Gangdese tarrane and the research samples were collected from volcanic stratata in Cenozoic. This work reports the new achievement in tectonics from apatite fission track studies. The apatite fission track results of total 5 samples have been obtained. Three samples of the results exhibit that the individual grain ages belong to a single population with a single mean age and have central ages of 5.9 +/- 0.7Ma, 5. 2 +/- 0. 6Ma and 8. 7 +/- 1.0Ma. Their mean track lengths are 13. 0 - 13. 2 +/- 2. 2 mu m with a single peak. These characterize the recent thermal event. The other two samples give spread individual grain ages and incluse 4. 9Ma and 29Ma, and 8.0Ma, 50Ma and 87Ma respectively. These group of ages resulted from pre-collision, syn-collision, post-collision and intracontinental rapid uplift separately. As a whole, there are two stages of goelogical thermal histories since the northwordly collision of the India into Asia. It is shown that main cooling-uplifting events occurred during 6 -0Ma and caused a cooling rate 11.3 degrees C - 16. 7 degrees C/Ma, an uplifting rate of 0. 85 - 0. 99mm/a and total uplifting scale of about 5100 - 5940m in this period.
