Poorly sorted sediment
WebSeveral factors can affect porosity. In sedimentary rock and sediments, controls on porosity include sorting, cementation, overburden stress (related to burial depth), and grain shape. Poorly sorted sedimentary deposits, in which there is a wide distribution of grain sizes, typically have lower porosity than well-sorted ones (Figure 11). WebAssociated with the wood fossils are abundant ammonites which, together with the ferruginous nature of the sediment, point to offshore sediment starvation. ... (Brachyphyllum, Podozamites), possible bennettitalean flowers (?Williamsonia), and abundant wood debris in a poorly sorted muddy sandstone with scattered coarse quartz grains.

Various types of clasts are shown in Figure 5.12 and in Exercise 5.3. The smaller ones tend to be composed of a single mineral crystal, and the larger ones are typically composed of pieces of rock.
