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.
WebIf all the grains are the same size, they are well sorted. Some sandstones are well sorted, and some are not. Most conglomerates are poorly sorted, and consist of a mixture of grain sizes ranging from sand to pebble. The schematic diagrams below represent poorly-sorted, moderately-sorted, and well-sorted sediments. Other Aspects of Texture WebSep 10, 2024 · Poorly-sorted sediments display a variety of sizes including cobbles, pebbles, and sand.

WebApr 14, 2024 · In the sandy-gravel Gobi, the sediments on the railway track had the smallest sorting coefficient (0.62), followed by the sediments on the west slope of the railway (0.69), and the sediments on the east slope foot of the railway (1.41) had the largest sorting coefficient, indicating that sorting of the east slope foot of the railway was the worst. WebMar 1, 2016 · The sorting index indicates that the Sandy Lake sediments are very poorly sorted from 43 cal ka B.P. to 24 cal ka B.P. after which the sediment texture is poorly sorted (Fig. 3). This is because the sediments deposited during the last glacial period have a mixed population of sediments that have been transported by both wind and glacio-fluvial …
WebGenerally, the flume experiments have been performed on well sorted sediments with unimodal grain size distribution, in order to understand relationship between grain size and flow velocity.
