摘要

A paleosol dated for about 500-700 kaBP and developed on a glacial deposit at ～ 3 000 m a . s. l. In the Yulong Mountains is studied using soil chemical, morphological and Mineralogical methods. The analytical results indicate that This soil was formed under tropical and humid conditions And can be classified as red soil, which cannot be formed in The present alpine environment at studied site. This im- Plies that the southeast margin of the Tibetan Plateau has Experienced intense uplift since the formation of the paleosol. According to the necessary conditions for the formation of The modern red soil in China, we estimate that the uplift Height of the Plateau since 500-700 kaBP would have ex- Ceeded 800 m.
