| 摘 要： | On the basis of mineralogical ,geochemical and micro-textural studies of the typical sections of the red weathering crust of carbonate rocks in the subtropical karst areas of Guizhou Province and Guangxi Autonomous Region,we have found,either on a microscopic or on a mac-roscopical scale and in different positions of the sections,the most direct and most important mineralogical and micro-textural evidence for the development of metasomatism in the process of weathering-pedogenesis of numerous carbonate rocks.This paper also has expounded for the first time and systematically the mechanism of metasomatism involved in the process of weathering-pedogenesis of carbonate rocks and proposed the sequence of mineral metasomatic evolution in the process of weathering-pedogenesis of carbonate rocks.

| Abstract: | On the basis of mineralogical, geochemical and micro-textural studies of the typical sections of the red weathering crust
of carbonate rocks in the subtropical karst areas of Guizhou Province and Guangxi Autonomous Region, we have found, either
on a microscopic or on a macroscopical scale and in different positions of the sections, the most direct and most important
mineralogical and micro-textural evidence for the development of metasomatism in the process of weathering-pedogenesis of
numerous carbonate rocks. This paper also has expounded for the first time and systematically the mechanism of metasomatism
involved in the process of weathering-pedogenesis of carbonate rocks and proposed the sequence of mineral metasomatic evolution
in the process of weathering-pedogenesis of carbonate rocks.
This research project was financially supported by both National Natural Science Foundation of China (Grant No. 4980003 )
