WebSome 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 Webis poorly sorted with well-rounded clast s that are larger than sand (cobble or pebble-sized) within a cementing fine-grained matrix. In a conglomerate, the rock fragments within are sub-rounded to rounded, implying that they traveled along a high energy water source such as a steep stream or river.
