On the basis of geological observation and laboratory analysis of some samples of rock and soil from four typical profiles of the weathering crust in Central Himalayas, southern Xizang, the auther of this paper has come to the following conclusions:1. The different types of weathering crust are distributed on various level of the Himalayas on account of the uplift of Himalayas and climatic change during Quaternary.2. Each typical profile of the weathering crust has clearly zonal feature and each zone both in chemical components and in minor element contents differs from each other.3. The distribution and enrichment of chemical elements are closely related to rock types and mineral assemblages of the related weathering crust as well as to the climatic conditions. Under the sub-tropical climatic condition for southern slope of Himalayas, SiO2 was partly lost from the weathering crust in the early stage of its development. The contents of SiO2, Fe2O3 and Al2O3 are higher than those for other three profiles of weathering crust.4. In this four profiles of weathering crust the contents of minor elements appear to be lower. The most strongly concentrated are Ti and Ba. The less enrichment are Zr and V. Moreover, an evident indication of increase of Ti and B from south to north slopes of Himalayas is observed.5. According to the features of distribution of chemical elements, the weathering crust can be divided into two distinct large types, i.e. progressive and retrogressive. In upper profile of retrogressive type of weathering crust Fe+++ is reduced into Fe++ and a great amount of Illite mineral is herein found.6. Under the influence of climatic and environmental changes the different geo-chemical process of weathering is related to different alpine superficial zone.
