WebApr 8, 2024 · The grains are poorly rounded as well as less sorted as compared to pure quartz sandstone rock. If we talk about its colour, it is grey to reddish. The grains are usually fine to very coarse but end towards the coarser side in the scale. If we talk about fossils in these type of sandstones, they are considered rare. WebSedimentary rocks generally have porosities in the range of 10% to 30%, some of which may be secondary (fracture) porosity. The grain size, sorting, compaction, and degree of cementation of the rocks all influence primary porosity. For example, poorly sorted and well-cemented sandstone and well-compressed mudstone can have very low porosity.
WebAug 20, 2024 · Geologists have also categorized sediment as well sorted and very poorly sorted. How do poorly sorted sediments differ from well sorted sediments? 1. n. [Geology] Well-sorted sediments are of similar size (such as desert sand), while poorly-sorted sediments have a wide range of grain sizes (as in a glacial till). A well-sorted sandstone …
