The general characteristics of the grain - size distribution of different sedimentary facies , es pecially the variations of the parameters mz ( mean particle diameter ) and o ( standard deviation ) clearly show that the fluvio - lacustrine facies and palaeosols usually become finer in particles and worse in sorting than the aeolian sands 该剖面不同沉积相粒度的一般分布特征尤其是粒度参数? mz 、的变化明显表现出,河湖相或古土壤通常要较风成砂颗粒细化,分选相对较差。
