Mastersizer2000 laser particle size analyzer was used in the grain-size analysis of quaternary sediments of a drill hole in the south of Shenzhou, Hebei. The measured data were used to plot frequency curves,cumulative frequency curves on probability scale, and granularity plural curve using the SigmaPlot software. On the basis of the grain size data from sediments of bore cores, geology background, and lithology in Shenzhou city, the analysis of quaternary sedimentary environment was performed according to the curve changes. Our study indicates that laser particle size analysis could give sequential grain-size information for the drawing of grain-size curves easier and reflect sedimentary environment and its imperceptible hydrodynamic condition changes.
