摘要
Taking a karst region of western Hunan Province as research area, and selecting four weathering profiles(of which, two are underlain by limestones, and other two by clastic rocks) as research object, through contrasting and surveying of characteristics of grain size distribution of quartz, this paper makes effort to unveil the formation of weathering crusts in the area. The parameters as standard deviation, skewness, kurtosis, etc. revealed by scatter diagram of quartz grain size indicate that each profile basically plots in different area. oft-com:office:office" />
