Comparative analysis of the Yecheng section at north piedmont of theKunlun Mountain, and the Surai Khola section at south piedmont of theHimalayan Mountain, suggests that the Qinghai-Tibet plateau is dominatedby continuous uplift over the past 10 million years, and the effectivetime scale for dividing the uplift stages is one million years. Theuplift processes of the plateau can be divided into three major stages,namely slow uplift of the entire plateau between 10.0-6.0 Ma.BP;transitional uplift stage between 6.0-2.5 Ma.BP(including medium-velocityuplift of the south part of the plateau and low-velocity uplift of thenorth part of the plateau during 6.0-4.6 Ma.BP; medium-velocity uplift ofthe entire plateau during 4.6-3.5 Ma.BP; and rapid uplift of the northpart of the plateau and medium-velocity uplift of the south part of theplateau during 3.5-2.5 Ma.BP). The entire plateau has been upliftingrapidly since 2.5 Ma.BP. The uplift elevation of the entire plateauexceeded 2000m above sea level by 4.6 Ma.BP and exceeded 3000m above sea level by 2.5 Ma.BP.
