摘要	We study the Neogene sedimentary environment of the Longgugou section in the Gyirong-Oma Basin, Xizang (Tibet) by means of paleomagnetic chronology. Analogy shows that Cenozoic fault-bounded basin on the north slope of Himalayas formed by 7.2MaB.P. And it shrank and died 3.2 MaB.P. It marked that the region around the Himalayas had experienced intensified uplift covering the interval from 7.2 to 3.2MaB.P. The age of Hipparion fossils localitied in the Longgugou section is about 7.0similar to6.7 MaB.P. In comparison with Hipparion fauna in North China, they should have similar geographic and climatic environment. Since the continual rise of the Himalayas, the fault-bounded basin subsided and the lake-basins attainted the biggest area during the period of 5.9similar to3.6 MaB.P. With the uplift of the Qinghai-Xizang Plateau and the subsidence of plain of North China I the topography of the west became higher than that of the east, and there had occurred great change in climatic environment between these two regions. For the reason of continually intensified uplift of Qinghai-Xizang 3.6MaB.P. the rivers in the west region cut through the ancient lake-basins and the lake basin of Gyirong-Oma contracted 3.2 MaB.P., died out 1.7 MaB.P., and then stepped into the stage of erosion and dissection.; We study the Neogene sedimentary environment of the Longgugou section in the Gyirong-Oma Basin, Xizang (Tibet) by means of paleomagnetic chronology.
