| The research and exploration about Tibetan Plateau have gradually gravitated towards the north of Tibetan Plateau and Geologists take the long-distance effect of two plate's collision as main aims since 1990s. At the same time, they think the key issue resolving the whole-uplift of Tibetan Plateau lay in the north of it. Liupan Shan connects with the Qilian Shan orogen through Haiyuan-Liupan faults and joins the Altyn Tagh strike-slip faults at last. They together form the tectonic border of the NE Tibetan Plateau. So the deformation and uplift histories of Liupan Shan hold the key to understand mechanisms of uplift of and testify current uplift models of the Tibetan Plateau. In addition to, Liupan Shan is an important boundary of current and ancient environment between the east and west in China. The Loess Plateau is set off by it. Opposite sides of it, strata age and cause of formation about the red clay as well as the enormous environmental difference between them have become hot spots of environmental effect of Tibetan Plateau in recent years. Hence, the research about the uplift process of Liupan Shan will further show the environmental effect of Tibetan Plateau uplift and bring the great scientific significance.Through the high-resolution magnetostratigraphy research about section of Longde and Jingyuan lying in the foreland basin west and east of Liupanshan mountain, we get the Tertiary sedimentary stratigraphic age, such as the underlying Sikouzi Formation with magnetostratigraphic ages from 32.2 Ma to 30.2Ma, the underlying Qingshuiying Formation from 30.2 Ma to 23.3Ma, and the underlying Gansu Group from 23.14 Ma to <16.2Ma respectively.Based on the ages of palaeomagnetism, we measure the magnetic susceptibility of Tertiary sedimentary stratum in Liupanshan areas( Jingyuan section, Longde section, Fenghuangdan section, Hejiakouzi section and Dingjiaergou section), the magnetic susceptibilities generally could be divided into four parts:①About 31.42～31.87MaB.P: The mean value of magnetic susceptibility is relatively high (14.2×10-8m3/kg) and frequency magnetic susceptibility is relatively low(5.5%);②About 31.42～23MaB.P, the mean value of magnetic susceptibility is relatively low (6×10-8m3/kg) with small amplitude and high frequency wave; and the mean value of frequency magnetic susceptibility is relatively high (13.33%) with big amplitude and high frequency wave;③About 23～15MaB.P. the mean value of magnetic susceptibility is relatively high with small amplitude wave (17.2×10-8m3/kg), and the mean value of frequency magnetic susceptibility is relatively low (6.77%) with big amplitude and high frequency wave;④Aboutl57.7MaB.P. the mean value of magnetic susceptibility is relatively high (17.2×10-8m3 /kg) with big amplitude and high frequency wave, and frequency magnetic susceptibility (7.8%) trends larger.We combine with lithology, lithofacies and sedimentary rates, referring to the deep-seaδ18O record; believing magnetic susceptibility and frequency magnetic susceptibility should be influenced by palaeoclimate, especially stable tectonic periods. Such as lacustrine facies of the Qingshuiying Format and Gansu Group, it could better record the global warming coming about 25.8MaB.P, and onset of the Asian Monsoon about 22.8MaB.P. Moreover, it could also indicate the enhancement of the Asian Monsoon about 15MaB.P.About 32.2～31.42MaB.P, several evidence such as mass coarse clastic grains close to sources depositing and turbulence of paleocurrents, and 31.87～31.42MaB.P, magnetic susceptibility increasing with opposite trendence of frequence magnetic susceptibility, in addition, the fluctuation of deep-seaδ18O record was not obvious during this period indicate that there was an intensive tectonic uplift in the Liupanshan mountain at that time. About 10～8MaB.P, several magnetic susceptibility increase with opposite trendence of frequence magnetic susceptibility, and accumulation of the gravel; especially, mass coarse clastic grains close to sources depositing and turbulence of paleocurrents at about 8Ma can prove that there could be several tectionic movements in the area during 10～8MaB.P and a rapid tectionic uplift at about 8Ma.
