Is Sandstone well sorted or poorly sorted? - Our Planet Today

WebA rock must meet all of these requirements to be considered breccia: Clastic Sedimentary – Formed from the cementing together of rock and mineral fragments; Coarse-grained – A significant portion of the rock consists of large (over 2 mm) grains; Poorly Sorted – Highly variable grain sizes, ranging from sand to pebbles or cobbles WebFigure \(\PageIndex{1}\): Well-sorted sediment (left) and Poorly-sorted sediment (right). When reading the story told by rocks, geologists use sorting to interpret erosion or transport processes, as well as deposition energy.
