几种沉积物图解法与矩值法粒度参数的对比研究及其意义

Comparison and its significance of grain-size parameters of several sediments with graphic method and moment method

通过几种沉积物图解法与矩值法粒度参数的对比,发现不同的沉积环境具有不同的粒度参数特征,这种特征的差异可以用来判别沉积环境。每一种沉积物的2种方法对比的粒度参数不同,说明针对同一样品粒度参数的2种计算方法结果具有一定的差异性,所以在参考前人的研究成果时需要特别加以注意。研究成果可供今后从事该项研究时参考。

By studying the grain-size parameters of several sediments with graphic method and moment method, it is found that different sedimentary environments have different grain-size parameters features, which could be used to discriminate sedimentary environment. The different results of these two methods show that they could cause difference in grain-size parameters of the same sample. Therefore, those previous researches should be used with caution. This paper could provide reference for future relevant research.
