Poorly sorted rock
WebFor example, wind-blown sands are typically extremely well sorted, while glacial deposits are typically poorly sorted. These characteristics help identify the type of erosion process that occurred. Coarse-grained sediment and poorly sorted rocks are usually found nearer to the source of sediment, while fine sediments are carried http://www.columbia.edu/~vjd1/sed_rx.htm

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. WebSome rocks will be made up of grains that are all the same size (or very close), while others will have a variety of grain sizes. In sedimentary rocks, we refer to uniform grain sizes as …
