%X 210Pb in carbonate sediments is derived from granule adsorption through the water cycle in soil and atmosphere.Moreover,different granules have different capabilities for the adsorption of 210Pb.The processes can be analyzed according to the 210Pb content.Using the 210Pb technique,the authors studied different modern carbonate sediments in different karst areas.The results show that the 210Pb technique can be reliably used to determine the velocity of carbonate sedimentation and calculate the time and velocity of carbonate sedimentation in the last 100 years through the study of the relationship between the depth of sediments and the ratio of 210Pb.It is concluded that the 210Pb technique can not only provide a means for studying carbonate sediments but also supply important information for modern karst development.
