Poorly sorted sedimentary rocks
WebNov 9, 2024 · Glacial sedimentation is very diverse and generally consists of the most poorly-sorted sediment deposits found in nature. The main clast type is called diamictite, which literally means two sizes, referring to the unsorted mix of large and small rock fragments found in glacial deposits [ 53 ]. WebSorting is the tendency of sedimentary rocks to have grains that are similarly sized—i.e., to have a narrow range of sizes (see Figure 2). Poorly sorted sediment displays a wide range of grain sizes and hence has …

WebJul 23, 2024 · Sorting describes the distribution of grain size of sediments either in unconsolidated deposits or in sedimentary rocks. … Very poorly sorted indicates that the sediment sizes are mixed (large variance) whereas well sorted indicates that the sediment sizes are similar (low variance). 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 …
WebSorting refers to the range of grain sizes in a sediment deposit or in a clastic sedimentary rock (Figure 5.3.5). Poorly sorted sediments contain a wide range of grain sizes. Deposits of glacial till, for example, tend to be very poorly sorted as they contain grain sizes ranging from house-sized boulders to very fine grains of clay. A deposit ... WebDetritus - the loose, fragmental debris produced by the mechanical breakdown of older rocks. Features of clastic sediments. Sorting - is the measure of range of particle size of sediments. A sediment having a wide range of particle size is said to be poorly sorted and if the range is small, the sediment is said to be well sorted.
