WebGeologists use the term “well-sorted” to describe a narrow range of grain sizes, and “poorly sorted” for a wide range of grain sizes (see figure) . It is important to note that soil … WebSorting. Sorting is the variability in grain size in a clastic sedimentary rock. This parameter measures how well a sediment has been ‘sorted’ by the process that transported it. A sediment can be: – very well sorted: nearly all grains have the same size. – well sorted: most grains fall in a single grain size class with few outliers.

Soil gradation is a classification of the particle size distribution of a soil. Coarse-grained soils, mainly gravels or sands, are graded as either well graded or poorly graded. Poorly graded soils are further divided into uniformly-graded or gap-graded soils. Fine-grained soils, mainly silts and clays, are classified according to their Atterberg limits. A well-graded soil is a soil that contains particles of a wide range of sizes and has a good repres… WebThe characteristics and distinguishing features of clastic sedimentary rocks are summarized in Table 6.2. Mudrock is composed of at least 75% silt- and clay-sized fragments. If it is dominated by clay, it is called claystone. If it shows evidence of bedding or fine laminations, it is shale; otherwise it is mudstone. diagnosis charting checklistWebDec 7, 2005 · BigH (Geotechnical) 1 Nov 05 20:59.
