Abstract

Sediments in basins couId record the ascending and descending difference of the earth crust. The sediments of the Late Cenozoic in the Jiuxi basin,Iocated in the northern margin of the Tibetan pIateau,have sensitiveIy and com-pIeteIy recorded the upIifting process of northern pIateau. The heavy mineraIs of sediments have the reguIatory variety in the Laojunmiao section of Jiuxi basin since 13 MaBP；detaiIed study of the heavy mineraI has reveaIed four heavy mineraI stages of sedimentary evoIution. they are： ①stabIe heavy mineraI associations before 12.18 Ma BP, ②reIativeIy stabIe heavy mineraI associations between 12.18 and 8.26 Ma BP, ③ unstabIe heavy mineraI associations between 8.26 and 4. 9 Ma BP,and ④ the very unstabIe heavy mineraI associations since 3.66 Ma BP. The associated mountain erosion and u-pIift are suggested having experienced three phases on the upIifting process of the northern Tibetan PIateau,that is,tec-tonic stabIe （13 ~ 8.26 Ma BP） ,graduaI staggered upIift （8.26 ~ < 4.96 Ma BP） ,and rapid intense intermittent mass upIift（ > 3.66 ~ 0 Ma BP）.
