Rather, substrates are characterized and identified by sediment grain-size composition (the sediment class); the distribution,The intrusive rocks shown in Figure 3.13 are all phaneritic, as are those shown in Exercise 3.6. In general, the size of crystals is proportional to the rate of cooling. The longer it takes for a body of magma to cool, the larger the crystals will be. It is not uncommon to see an intrusive igneous rock with crystals up to a centimetre long.The USCS has three major classification groups: (1) coarse-grained soils (e.g. sands and gravels ); (2) fine-grained soils (e.g. silts and clays ); and (3) highly organic soils (referred to as "peat").
