| Abstract: | Grain size analysis of the sediments is very important to differentiate sedimentary environments,determinate the ways of sediments transporting,estimate hydrodynamic conditions and to analyse grain size trends. The authors introduced the methods and advance of grain size analysis technique,including direct measurement,sieving analysis,setting method and the laser grain-size analyzer;and evaluated the classification method,sediment naming and its applications. The authors pointed out that the classification of the sediments played an important role in grain size trends analysis and concluded that along with the development of the computer technique,the grain size analysis will be more automatic and diversified in both operation processes and the testing contents,and will be applied more widely. |
